Answer:

x = -2

Step-by-step explanation:

2+3x = −4(5+2x)

2+3x = (−4)(5)+(−4)(2x)(Distribute)

2+3x = −20+−8x

3x+2 = −8x−20

3x+2+8x = −8x−20+8x

11x+2 = −20

11x+2−2 = −20−2

11x = −22

11x/11  =  −22/11

therefore, x = −2

Answer:

X= -2

Step-by-step explanation:

So first distribute on the right side

2+3x=-20-8x

Now add 8x on both sides

2+11x=-20

Now subtract 2 on both sides

11x= -22

Now divde 11 on both sides

-22/11

x=-2

Step-by-step explanation: n Euclidean geometry, an isosceles trapezoid is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can be defined as a trapezoid in which both legs and both base angles are of the same measure.

Area: ½ x (sum of the lengths of the parallel sides) × height of the trapezoid

Perimeter: the sum of the top and bottom sides+2(leg of the trapezoid)

Number of vertices: 4

Number of edges: 4

Patti ran the race in 7.1 minutes. Maisha ran it in 7.01 minutes.

What is the value of the 1 in Maisha's time? ?

What is the value of the 1 in Patti's time?

Answers

Answer:

The value of 1 in Maishas time is hundredth

The value of the 1 in Pattis time tenth

Step-by-step explanation:

The place value of decimals begins at tenth and extends towards the right. Hence, the one decimal place in Pattis time has the value of tenth while the 1 in  Maishas time occurring at the second decimal place has a place value of hundredth.

Hence the place value of decimals may be tenth, hundredth, thousandth etc depending on the number of decimal places and the digit of interest.

What is the slope intercept form.

Answers

Answer:

y = -[tex]\frac{3}{7} x - 2[/tex]

Step-by-step explanation:

slope-intercept form : y = mx + b

Solve for y.

Subtract 3x on both sides. You get --> 7y = -3x - 14

Divide by 7 on both sides. You get --> y = [tex]\frac{-3x-14}{7}[/tex]

Simplfy it. -14/7 = 2 so you get y = -[tex]\frac{3}{7} x - 2[/tex]

Cot (15 degrees)
Part I: Find two common angles that differ by 15 degrees. Rewrite this problem as the cotangent of a difference of those two angles.
Part II: Evaluate the expression (Please show steps)

Answers

Answer:

Part I: cot(15 degrees) = cot(45 - 30)

Part II: Evaluation is below

Step-by-step explanation:

Everything is done in degrees

Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)

We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:

(4 + 2sqrt(3))/2 = 2 + sqrt(3)

I hope this helps! :)

y = 4x + 2


y = 2x + 2


y = 2x + 4


y = 4x -2

Answers

Answer:

y=2x + 4

Step-by-step explanation:

Y=4x+2

Plug in what they gave you to the formula y=Mx+b
The slope was given 8/2 —> simplify =4
And we don’t know what x and y is so we leave the variables like how it is
They gave us the y intercept which is B so plug in positive 2
So plug it into the equation
Now we have
y=4x+2

e. The probability of drawing an ace in a standard deck of cards is 0.08. Seven cards are drawn without replacement. The random variable represents the total number of ace cards observed.

Answers

Answer:

A & C

Step-by-step explanation:

Option A: The variable described is binomial because we have a value of n for the experiment and a probability of success 0.5 due to the fact that we have only two possible outcomes, which satisfy the condition of chances of success and failure.

Option B: The variable described is not binomial because the outcome does not fall under the criteria of chances of success or failure of due to the fact that it's possible we have more than two criteria to classify the product.

Option C: The variable described is binomial because we have a definite value of n = 6 with a probability of success = 0.3. Thus, probability of failure will be 0.7 and so it fulfills the condition of success and failure.

Option D: The variable described is not binomial because we don't know if the 2 options are independent of each other.

Option E: Variable describes is not binomial because the cards are drawn without replacement. Also, each time that king is selected, the probability of another king being selected is not the same and for thus the variable is not a a binomial

The measure of the exterior angle of the triangle is

Answers

The question is incomplete below you will find the missing part.

The measure of the exterior angle of the triangle is

The missing picture is shown below.

The measure of exterior angle of the triangle is 92°.

As we know, the measure of the exterior angle of triangle is the sum of the two interior opposite angles of the triangle. In other words, we can say that the sum of two interior angles in the triangle is equal to the exterior angle which is supplementary to the third interior angle of the triangle.

So here the exterior angle of the triangle is given by (2x-2)°

the measure of its two interior opposite angles of the triangle will be x° and 45°.

So using the above concept

the measure of exterior angle =  sum of the two interior opposite angles

⇒ 2x-2= x+45°

⇒2x-x = 45°+2°

⇒x =47°

the measure of exterior angle will be = 2x-2= (2*47°)-2 =92°

Therefore the measure of exterior angle of the triangle is 92°.

What's 10/7 divided by 3/7

Answers

Answer:

3 1/3

Step-by-step explanation:

Answer: 3-1/3.

1. Convert the second fraction into a reciprocal. 3/7 turns in 7/3.

2. Multiply the fractions; multiply the denominator with the denominator and the numerator with the numerator. 3/7 x 7/3 = 70/21.

3. Simplify the result; divide both the numerator and denominator by 7 (their common multiple). 70/7 = 10, and 21/7 = 3. So, now you have 10/3.

4. Convert the reciprocal fraction. 10/3 = 3-1/3.

This is Miss Deirdre Willis. Shes just moved here from Maryland. I know youll all welcome her. I stood at the front of my first-period class with Mr. McCurdy, the seventh-grade English teacher . . .2 I noticed that the kids in my class were checking me out like nobodys business. At first, I thought they were only gawking at my camera, but their eyes moved from my hair to my sweater, down to my shoes, then back and forth at each other.3 I shrugged and swallowed and didnt look at any of them, my heart still pounding like bongos in a band.4 Miss Willis, theres your seat, over there. Take it, wont you please. Mr. McCurdy pointed to an empty desk toward the front of the room. I sat down, cradling my camera in my lap. I carefully looked right, then left.5 Mr. McCurdy rubbed his hands together. Now listen up. Today were starting our unit on great American poets. Who can name some?6 The other kids were slow to answer, so I raised my hand. When Mr. McCurdy called on me, I cleared my throat. That lump was still resting there from before. Langston Hughes, I said softly.7 Hughes. L-a-n-g-s-t-o-n H-u-g-h-e-s. Mr. McCurdy wrote the poets name on the blackboard.8 Langston who? asked a red-haired girl sitting next to me.9 I thought everybody knew who Langston Hughes was. I sucked my teeth silently and folded my arms. Then I glanced around to get a better look at the red-haired girl.10 Hughes. A fine poet. One of our best, Mr. McCurdy was saying. Miss Willis, stand up, please, and expand on Langston Hughes. I pushed my glasses up on my nose and stood up.11 Well, sure, I said, watching the red-haired girl out of the corner of my eye. Langston Hughes was an African-American poet who got popular in the 1920s and 1930s. He wrote plays and essays too. I spoke slowly and carefully. My fidgety heart started to beat regularly again.12 And Langston Hughes helped shape what is known as the Harlem Renaissance,1 Mr. McCurdy explained.13 He spent a year in Mexico with his father after he was done with high school, I added.14 Born in Joplin, Missouri, Mr. McCurdy said.15 His poem The Weary Blues won him a prize. Mr. McCurdy and I, we were on a roll.16 The Weary Blues turned out to be the title of Hughess first book of poems, published in 1926, he said.17 Id never had a teacher go on with me like that. Mr. McCurdy knew a lot about Langston Hughes. He looked pleased that I knew almost as much as he did. In his broken-hinge voice, he said, Thatll be all for now. Your seat, Miss Willis. You may take it.18 Everybody got quiet; I guess they were waiting for me to sit down. But I didnt want to take my seat; I didnt want to take any seat. I was just getting started. Those kids were still staring, still checking me out. I wanted to tell them more about Langston Hughes, and about the other African-American poets who are my favoriteslike Gwendolyn Brooks and Nikki Giovanni.19 The red-haired girl was paying attention, listening to me and Mr. McCurdy talk about Langston Hughes. I dont think she knew what to make of me. When I caught her staring, her eyes turned away.20 When the bell rang, I let out a breath and gathered my books. The other students huddled together in groups of twos and threes, leaving me alone in the classroom with Mr. McCurdy.21 Youve got a fire for good poets, I can see that, he said, clasping my hand with a two-handed handshake. I gently pulled my hand free and adjusted my knapsack.22 Mr. McCurdy gestured toward my camera. Maybe someday youll show us all how you use that thing, he said.23 As he left, the door brushed closed quietly behind him. I looked back at the empty classroom.
