Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Amy drove to her Mother’s house, which is 204 miles away. If it took her 3 hours, what was her average speed mph?
Answer:
68
Step-by-step explanation:
204/3 = Avg MPH
Answer:
Speed=1/68
Step-by-step explanation:
Remember the equation speed= distance/time.
Plug in. We know the distance and we know the time. Our equation will look like this:
Speed= 3/204
Lets simplify to get 1/68.

In triangle ABC, D is the midpoint of side AC and E is the midpoint of side BC.
What is the value of x?
Answer:
14
Step-by-step explanation:
Since all sides are half of greater triangle.Then 7 × 2 = 14 is length of greater hypotenuse.
Suppose two triangles with similar conditions
1^2+1^2=2
Hypotenuse=2^1/2
We assume another triangle which is exactly double of previous triangle I.e
2^2+2^2=8
Hypotenuse=2×2^1/2
Which is exactly twice of previous triangle.
Hence proved hyootenuse is double of smaller triangle I.e 14

Answer:
65 degrees
Step-by-step explanation:
Answer:
Option B is correct 65°
Step-by-step explanation:
Apply the trigonometric identity sine
[tex]sin\ x=\frac{6.1}{6.7}\\\\sin\ x= 0.9104\\x=sin^{-1}(0.9104)\\x=65[/tex]
Do not forget to convert your calculator into degree form if it is set to radian.
Alright since you haven't studied trigonometry forget what i said here xD
The table given are the ratios of the respective angles 55, 65, 75.
First we need the adjacent side of the triangle. We have the opposite side of the triangle which is 6.1 and the hypotenuse which is 6.7 we use Pythagoras theorem
[tex]a^2+b^2=c^2\\a^2+(6.1)^2=(6.7)^2\\a^2=(6.7)^2-(6.1)^2\\a^2=7.68\\a=\sqrt{7.68}\\a=2.77 \\[/tex]
So now lets compare the ratios in table
Firstly
[tex]\frac{adjacent\ leg \ length}{hypotenuse\ leg \ length} = \frac{2.77}{6.7}=0.413\\\\\frac{opposite\ leg \ length}{hypotenuse\ leg \ length}=\frac{6.1}{6.7}=0.91 \\\\\frac{opposite\ leg \ length}{adjacent\ leg \ length}=\frac{6.1}{2.77}=2.2[/tex]
so we can see that all these values 0.413, 0.91, 2.2 correspond to the angle 65° so Option B is correct
Daniel worked for 2 hours and earned $18.20.
How much would he make if he worked for 5 hours?
Enter your answer in the box.
Answer:
$45.50
Step-by-step explanation:
First we'll need to solve for how much Daniel earns per hour.
So 18.20/2 = $ 9.10
Then we'll be multiplying this value by 5 since the question is asking how much he earns if he works for 5 hours.
$ 9.10 x 5 hours = $45.50

Answer:
2nd option
Step-by-step explanation:
solve for x
step 1: add 1 to both sides to get
2x ≥ 1
Step 2: divide both sides by 2 to get
x ≥ 1/2
so any number greater than or equal to 1/2
Answer:
B or 2x - 1 ≥ 0
Step-by-step explanation:
Here are the steps:
2x -1 ≥ 0
+1 +1 =
2x ≥ 1
÷2 ÷2 =
0.5 so
x ≥ 0.5

You draw one card from a standard 52-card
deck. In how many ways could the card be a
face card or a red card?
Answer:
23%
Step-by-step explanation:
There are 52 cards in a deck… 12 of these are Face Cards (the J - Q - K of all four suits). The probability of getting one of these is therefore 12 out of 52 — or 12/52, which is 23%.

Answer:
x=27.8
Step-by-step explanation:
first, you need to find y. 2y-5=65. 65+5 is 60 and you are left with 2y=70. to get the 2 off of the y you divide everything by 2. 70/2 is 35 therefor y=35. Now you plug that into the other equation (2x+y) and get 2x+35 which is equal to segment 90.6 so 2x+35=90.6. subtract 35 on both sides and you have 2x=55.6. To get the 2 off the x, we divide everything by 2. all of that divided by 2 is x=27.8
17.Becky has a large bag of M&Ms that she knows she should share with Jaeyun.
Jaeyun has a packet of Starburst candy. Becky tells Jaeyun that for every

Two hot air balloons are flying above a park. One balloon started at a height of 3,000 feet above the ground and is decreasing in height at a rate of 40 feet per minute. The second balloon is rising at a rate of 50 feet per minute after beginning from a height of 1,200 feet above the ground.
Given that h is the height of the balloons after m minutes, determine which system of equations represents this situation.
A.
h = 3,000 + 40m
h = 1,200 - 50m
B.
m = 3,000 - 40h
m = 1,200 + 50h
C.
h = 3,000 - 40m
h = 1,200 + 50m
D.
h = 3,000m - 40
h = 1,200m + 50
Answer:
C
Step-by-step explanation:
Because c has the variables in the right spot and the other ones don't make scene
Answer:
h = 3,000 - 40m
h = 1,200 + 50m c.

Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex.
Coordinates: (4,-4) (-1,-6). (6,-8)
Answer:
(1,-8)
Step-by-step explanation:
We were given three vertices of a parallelogram to be:
(3,-2), (-1,-4), (5,-6).
After plotting the points as shown in the attachment, we realize (3,-2) and (-1,-4) form a diagonal.
The midpoint of this diagonal using the midpoint formula is
is
Recall that, the midpoint of both diagonals are the same.
Let the fourth point have coordinates (x,y).
Then using the midpoint formula again with (3,-2), we have:
This implies that:
and
and
x=1 and y=-8
The coordinates of the fourth point are:
(1,-8)
Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.4)(1.8)(−3.25) (-49)(-34)(-12)(-12) −1(3.5−7) How many expressions will have a product that is positive?
Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.
