Answer:
x=-8
Step-by-step explanation:
We are solving for the variable, x, so let us isolate all terms of x. Let us start by moving the numerical value 2 to the right side, thereby isolating the term 2x on the left:
2x= -18+2
2x=-16
So close! Let us divide both sides by 2 now:
x= -8
I hope this helps! Please let me know if you have any further questions :)
Answer:
-8
Step-by-step explanation:
Hey there
steps:
2x-2=-18
add 2 to both sides:
2x-2+2= -18+2
simplfy:
2x= -16
divide both sides by 3 :
[tex]\frac{2x}{2} = \frac{-16}{2}[/tex]
simplfy :
x = -8

Write an equation that represents the line?
Answer:
An equation that represents the line is:
y = 3/4x - 9/2
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the attached graph of a line.
Taking two points from the line, such as
(2, -3)(6, 0)Determining the slope between (2, -3) and (0, 6)
[tex]\left(x_1,\:y_1\right)=\left(2,\:-3\right),\:\left(x_2,\:y_2\right)=\left(6,\:0\right)[/tex]
[tex]m=\frac{0-\left(-3\right)}{6-2}[/tex]
refine
[tex]m=\frac{3}{4}[/tex]
substituting m = 3/4 and the point (2, -3) in the slope-intercept form of the line equation
y = mx + b
[tex]\left(-3\right)=\frac{3}{4}\left(2\right)+b[/tex]
[tex]\frac{3}{2}+b=-3[/tex]
subtract 3/2 from both sides
[tex]\frac{3}{2}+b-\frac{3}{2}=-3-\frac{3}{2}[/tex]
[tex]b=-\frac{9}{2}[/tex]
now substituting b = -9/2 and m = 3/4 in the slope-intercept form of the line equation
y = mx + b
y = 3/4x + (-9/2)
Therefore, an equation that represents the line is:
y = 3/4x - 9/2
What is the probability of rolling a two or not rolling a 2 using a regular six sided number cube

What is the probability that a student selected at random takes math or drama? (round answer to 3 decimal places)
Distribution table for the question is attached below :
Answer:
0.533
Step-by-step explanation:
Let :
M = math
D = Drama
Probability that a randomly chosen student takes math or drama ; P(M u D)
Recall:
P(A u B) = p(A) + p(B) - p(A n B)
P(M u D) = p(M) + p(D) - p(M n D)
Probability = required outcome / Total possible outcomes
From the table :
P(M) = 119 / 302
P(D) = 67 / 302
P(M n D) = 25 / 302
Therefore,
P(M u D) = 119/302 + 67/302 - 25/302
P(M u D) = (119 + 67 - 25) / 302
P(M u D) = 161 / 302
P(M u D) = 0.5331125
P(M u D) = 0.533 ( 3 decimal places)

A rectangular mural has a length of $\ell$ centimeters and a width 30 centimeters less than its length. How much does it cost to border the outside of the mural using 1-centimeter square tiles that cost $2 each?
I don't no this answer so sorry
The cost to border the outside of the mural using 1-centimeter square tiles is 600 dollars.
What is Rectangle?A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.
We have been given that a rectangular mural has a length of 90 centimeters and a width of 30 centimeters less than its length.
Length = 90 cm
Width = 90 - 30 = 60 cm
The formula to calculate the perimeter of a rectangle,
Perimeter = 2(length + breadth)
Perimeter = 2(90 + 60)
Perimeter = 2(150)
Perimeter = 300
Therefore, the cost to border the outside of the mural using 1-centimeter square tiles costs $2 each.
= 300 x 2
= 600 dollar
Therefore, the cost to border the outside of the mural using 1-centimeter square tiles is 600 dollars.

Nellie's Tea Shop has caffeinated tea and decaffeinated tea. During the lunchtime rush, the tea shop served 40 teas in all, 70% of which were caffeinated. How many caffeinated teas did the tea shop serve?
Answer: 28 caffeinated teas
Step-by-step explanation:
The tea shop served 40 teas in all.
70% of this 40 were caffeinated.
The actual number that was caffeinated is therefore:
= Number of teas served * Caffeinated percentage
= 40 * 70%
= 28 caffeinated teas
1) Jayden states that based on the Congruent Supplements Theorem, if
mZ1 +mZ2 = 90° and if mZ1 +mZ3 = 90°, then 22 =23. What is
the error in Jayden's reasoning?
Answer:
The congruent supplements theorem states that 2 angles are supplementary if they add up to 180 degrees, not 90 degrees.
He should have stated the complimentary theorem instead.
Step-by-step explanation:
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.
Given:
∠1 +∠2 = 90° and if ∠1 +∠3 = 90°, then ∠2 =∠3
To find:
The error in Jayden's reasoning
Solution:
According to Congruent Supplements Theorem, the sum of supplementary angles is equal to 180°, not 90°.
[tex]\angle 1 +\angle 2 = 180^o\\\angle 1 +\angle 3 = 180^o\\\text{From this, we can conclude that}:\\\angle 2 = \angle 3[/tex]
The error in Jayden's reasoning was 90°.
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.

Choose the correct comparison for the numbers below.
0.85, 3/4, 91%
a. 3/4 > 0.85 > 91%
c. 91% > 3/4 > 0.85
d. 0.85 < 3/4 < 91%
Answer:
A
Step-by-step explanation:
In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.
The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.
Since 0.85 is already in decimal form, leave it as it is.
3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:
[tex]\frac{3}{4} * \frac{25}{25} = \frac{75}{100}[/tex]
Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.
91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.
Now that you can see the numbers, just rearrange them from least to greatest
0.75<0.85<0.91
equal to A

3. Michael says he can move ABCDE onto A"B"C"D"E" with one transformation by translating ABCDE diagonally so that it moves 8 units up and 10 units right. Is he correct? Explain why or why not.
Answer:
Michael is incorrect.
if we take the steps Michael says and move the ABCDE up 8 and right 10, not all of the points line up.
Step by step explanation:
In order to get the shapes to line up, we need to flip (reflect) ABCDE onto the 2nd Quadrant, then we can move (translate) it to the right by 10.

The solution to the product of the two figure is 1 trillion
The product of two given figuresTo know how much the product of this figures is
1000000 x 1000000 = 1 trillion
To calculate this, we can multiply 1,000,000 (1 million) by itself:
1,000,000 x 1,000,000 = 1,000,000,000,000
So 1000000 x 1000000 is equal to 1 trillion (1,000,000,000,000).
1 trillion is a very large and significant number that is often used to describe quantities on a global or macroeconomic scale.
