A system of two equations is shown below. What will you need to multiply the

1 answer:

6 0

In order to solve this equation you must eliminate one of the variables.

By multiplying by -3 you eliminate the y variable, making A the correct answer.
-6x-3y=-66
5x+3y=29
-x=-37
x=37

If you would like further explanation let me know. :)

Calculate the area of each shape below. Figures are not drawn to scale.

Answer:

The area of the triangle is 168 meters

Step-by-step explanation:

Formula to find the area of a triangle:

Area = 1/2 Base x Height

So, first you need to identify the base and the height. The base is 16m + 8m, and the height is 14m. All you have to do is plug in the numbers:

Area = 1/2 (16 + 8) x 14

Then, you solve:

Area = 1/2 (16 + 8) x 14

Area = 1/2 24 x 14

Area = 1/2 336

Area = 168 meters

So, the area of the triangle is 168 meters

Kyle has a storage box that is 2 ft. long, 3 ft. high, and has a volume of 12 ft.3

Eva8 [605]

Alright, let get started.

Kyle has a storage box having dimensions 2 ft long, 3 ft high and volume 12 cubic feet.

The formula for volume is = $length * width * height$

Suppose the width is w so,

$12 = 2 * 3 * w$

$12 = 6w$

Dividing by 6 in both sides

w = 2 feet

Myla has a storage box that is 4 ft high and 2 feet long and volume 16 cubic feet.

Suppose the width is w hence

$16 = 4 * 2 * w$

$16 = 8 w$

Dividing 8 in both sides

w = 2 feet

Hence the width of Kyle and Myla's boxes, both are 2 feet. : Answer

Hope it will help :)

Find the slope of the line through these pair of points. (12,-18) (-15,-18)

zysi [14]

The slope, m, is given by the equation m = (y2-y1)/(x2-x1), where (x1, y1) and (x2, y2) are points on the graph. Thus:
m = (-18-(-18))/(-15-12)
= (-18+18)/-27
= 0/27 = 0
Therefor the slope is 0

Answer:

$x = -105$

Step-by-step explanation:

What number divided by -7 is equal to -15

∨ ∨ ∨ ∨ ∨

x ÷ -7 = -15

Multiply -7 to both sides:

$\frac{x}{-7}=15$

$x = -105$
