Salutations!

First, add -2y to both sides.
-3x + 2y + -2y = 12 + -2y
-3x = -y + 12

Second, divide by -3 on both sides.

\frac{-3x}{-3} =   \frac{-2y + 12}{-3} 

x =  \frac{2}{3} y - 4

Hope This Helps!!!

Answer:

188.49

Step-by-step explanation:

use the diameter to find the circumference..

C = d pi          or C = 2r pi

when you plug in 20, you get 62.83

now take that, and multiply it by 3, because the wheels went around three times.

62.83 * 3 = 188.49  inches

Brian has 16 yards of chain measured and cut at the. Hardware store. The chain will cost him 47.52$ how much is that per food? _
mojhsa [17]
3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot. 

Find the unit rate. 

49.50/50= 0.99

No, it wouldn't. It would be the <em>same price 

0.99=0.99
It doesn't matter which one Brian chose. </em>

I hope this helps!
