Answer:
b) -5
Step-by-step explanation:
-5 x/x
We can cancel the x/x because it equals 1
-5 (1)
-5
30 red cars
3x + 5x = 240
8x = 240
x = 30
red:blue = 3:5
30
the solution of the equation.
33.92
40 x .2= 8
40-8= 32
32x.06=1.92
32+1.92= 33.92
4:3 total is 7
8:6 total is 14
12:9 total is 21
So there are 9 girls.
