# A rectangle has a length of 7 and a width of 5. Which of the following equations represents a way to find the perimeter of the rectangle

Answer from: comeonmanim

(x + 16) / 3 = 3xx + 16 = 3 * 3xx + 16 = 9x16 = 9x - x16 = 8x16/8 = x2 = x < 3(x + 1) = -2(x - 1)3x + 3 = -2x + 23x + 2x = 2 - 35x = -1x = -1/55x + 2 = 4x - 95x - 4x = -9 - 2x = - 11p = 2(l + w)125 = 2(l + 5)125 = 2l + as 2x + 10 = 125125 - 10 = 2l115 = 2l115/2 = l57.5 = is 57.53/4x + 5/8 = everything by 86x + 5 = 32x5 = 32x - 6x5 = 26x5/26 = xx = 0.8x + 72x - 0.8x = 720.2x = 72x = 72/0.2x = 360

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

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
