X - Linda's speed
(x+8 )- Colleen's speed
8x - Linda's distance for 8 h
8(x+8) = 8x+64 - Colleen's distance for 8 h
8x + 8x + 64 = 176 - distance between Colleen and Linda after 8 h
8x + 8x + 64 = 176
16x +64 = 176
16x = 176 - 64
16x = 112
x= 7 mph Linda's speed
x+8 = 7+8 = 15 mph Colleen's speed
13 lbs shared between 3 batches . . .
13/3 = 4 1/3 lbs each
The two whole numbers would be 4 and 5
w + 15 since increased by 15 means add on
12y + 11 since product of 12 and y means multiply 12 and y = 12y
one half n - 16 since one half of n and decreased by 1 6 , subtract 16
2b - 6 since Corinne is 6 years younger represented by b - 6
sum of their ages = b + b - 6 = 2b - 6
9h + 40
$ 9 per hour for h hours = 9 × h = 9h plus the $ 40 from carpool

Triangles are 180 total so just add 118 and 22 then subtract it from 180 for your answer
