8. The drama club had a car wash as a fundraiser. Members washed x cars at $5
each and y trucks at $8 each. They made
$250. Find the number of each type of
vehicle they washed using the system of
equations:
(x - y = 11
5x + 8y = 250
A 15 cars and 26 trucks
B 22 cars and 33 trucks
C 26 cars and 15 trucks

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
