Step-by-step explanation:

texaschic101 is correct for all of them expect for the last one (question 6) she needed to finish the problem by multiplying 360 by 80%

step-by-step explanation:

x=0.8x+72

x=0.8x-0.8x+72 (move like terms to the same side)

0.8x-x=72 (collect like terms)

0.8x-x=0.2x

0.2x=72 (divide both sides by 0.2)

x=360

now because it said 80% of members were 30-40 and wants to know how many members joined between the age of 30 and 40 we need to multiply 360 and 80%

360 x 80%= 288

x=288

A 2.4 + n = 30 ; n = 27.6

Step-by-step explanation:

3x / 2

5x/9 + 10

6x - 4

x = 3y + 8

Associative Pr

operty of addition

3H + 4D + 5C = 85

(6 + t) / 3x

n + 7 <= 13

1 =< x <= 10

x = 6 or x = 1
