Estimate. then choose a method to find the product. 31x43

120

Step-by-step explanation:

first round both numbers because we're estimating

31 is about 30

43 is about 40

these numbers are easier to multiply

30 x 40

=120

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!
