Answer:

4 : 1

Step-by-step explanation:

To convert 2/20 : 1/40 to unit rate, we simplify the left side. So.

2/20 : 1/40 = 1/10 : 1/40

We now multiply both sides by 40.

So, 1/10 : 1/40 = 40 × 1/10 : 40 × 1/40 = 4 : 1

So, our unit rate is 4 : 1

2x - 3y = 8 // <br><br> Find y

konstantin123 [22]

Answer:

$y = -\frac{2}{3} x - \frac{8}{3}$

Step-by-step explanation:

$2x - 3y = 8\\$

Isolate y

$-3y = 8-2x\\-3y = -2x+8$

Divide both sides of the equation by -3

$\frac{-3y}{-3} = \frac{2x}{-3} +\frac{8}{-3} \\\\y = -\frac{2}{3} x - \frac{8}{3}$

This is really simple i just need help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Svetach [21]

It will stay the same.

$\frac{2(4)}{4} = 2$
$\frac{2(3)}{3} = 2$
$\frac{2(2)}{2} = 2$
$\frac{2(1)}{1} = 2$
No matter what you multiply 2 by, dividing it by the same number cancels it out, always leaving you with 2.
