Answer:

-3

Step-by-step explanation:

1) first combine all the like terms(terms with same variables or terms without any variable) together

1-7=-6

-6-7x=15

add 6 on both sides to remove it

-7x=21

divide both sides by -7

x=-3

Hope this helps

Answer:

Step-by-step explanation:

So first we combine like terms on the left

1-7=-6

then we have

-7x-6=15

next we add 6 both sides

-7x-6=15

+6 +6

-7x=21

then we divide -7 each side

we get

x=-3

Answer/Step-by-step explanation:

Recall: $x^{-a} = \frac{1}{x^a}$

a. $4^{-3} = \frac{1}{4^3} = \frac{1}{64}$

b. $13^{-2} = \frac{1}{13^2} = \frac{1}{169}$

What is the surface area of the cylinder with height 2 yd and radius 3 yd? Round your answer to the nearest thousandth.

olasank [31]

<h2>Given :</h2>

height (h) = 2 yd

radius (r) = 3 yd

<h2>Solution :</h2>

$\boxed{ \mathrm{Surface \: Area = 2\pi r(h +r )}}$

$2 \times 3.14 \times 3 \times (3 + 2)$

$18.84 \times 5$

$\boxed{\mathrm{94.2 \: yd {}^{2} }}$
