Write an equation for the total amount y after the given rate of increase is added to the original amount x. 20%

y = 1.2x

Step-by-step explanation:

The given original amount is x.

Increase = 20%

Increase =

Increase = 0.2

Amount of increment = 0.2x

Total amount = Original amount + Amount of increment

y = x + 0.2x

y = 1.2x

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
