rafael counted a total of 40 white cars and yellow cars. There were 9 times as many white cars as yellow cars. how many white cars did rafael count?
x- yellow cars
9x- white cars
x + 9x=40
10x = 40 / divided by 10
X= 4
there were 4 yellow cards and 36 white cars . hope this help you .
If x= Number of yellow cars then. White cars =9x
X +9x=40
10x=40
X=40/4=4
Number of yellow cars is 4
Number of white cars is 94 =36
