Rewriting 0.4(x - 2) = 3.4 -0.2x in problem 3-120 gave you at least one new, equivalent equation that was much easier to solve. Two equations are equivalent if all of their solutions are the same. There are several ways to change one equation into a different, equivalent equation. Common ways include: adding or subtracting the same number from both sides, or multiplying or dividing both sides by the same (non-zero) number.

Rewrite an equivalent equation for each equation below. Be sure your equivalent equation has no fractions or decimals. Then solve the new equation and check your answer in the original equation.

a. -7.5.2 - 4.82 0.3 = 2.5c? + 10.02 - 1022

b. 2000(23 - 24) + 5000 = 18,000

1. 34

2. 268

3. x=14.4

step-by-step explanation:

are you an artist's daughter? cuz dang you a fine piece of art, girl.

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is 2

no you have to divide

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
