The length of a rectangle is two more than three times its width. If the perimeter of the rectangle is 92 meters, find the dimensions.
Let x = width, let 3x + 2 = length
2(x) + 2(3x+ 2) = 92
2x + 6x + 4 = 92
8x = 88

Solve Multistep Absolute Value
|3 - 6p| = -9
-5
p = {-7, 8}
(-5)|3 - 6p| / -5 = -9 (-5)
|3 - 6p| = 45 |3 - 6p| = -45
3 - 6p (-3) = 45 -3 3 - 6p (-3) = -45 -3
-6p = 42, p = -7 -6p = -48, p = 8
5(2x+6)=-4(-5-2x)+3x
What is x=10
10x + 30 = 20 + 8x + 3x,
10x + 30 = 20 + 11x
10 = x
Find two consecutive ODD numbers such that the sum of the larger number and twice the smaller number is 27 less tan four times the smaller number.
What is 29, 31
Let x = 1st Odd Consecutive Number, Let x + 2 = 2nd Consecutive Odd Number
x + 2 + 2(x) = 4(x) -27
3x + 2 = 4x - 27, 2 = x - 27, 29 = x, 31 = x + 2
Solve V = 1/3*pi *r2*h for h

Maria and Tim sold candy bars for a fundraiser. Maria sold seven less than twice the number of candy bars that Tim sold. In total Tim sold 137 candy bars. How many candy bars did Maria sell?
What is ... 89 Candy Bars.
Let x = Tim's sales, let 2x - 7 = Maria's sales
x + 2x - 7 = 137
3x = 144, x = 48, 2(48) -7 = 89
