1) find 25% of 80. 2) 13 is 11% of what number? 3) 27 is what percent of 9? 4) what percent of 350 is 290? 5) 1 is 4% of what number?

1 = 20

2 = 15

3 = 3

4= 15

5 = 2-

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

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!
