Answer: 28
Explanation: 40% of 80 is 32. 32+20 = 52. 80-52=28
So 32 cars are silver, 20 cars are red, and 28 cars are white
We have a pair of vertical angles here. So they would equal each other.
3x+50=6x-10
Subtract 3x to 6x:
50=3x-10
Add 10 to 50:
60=3x
Divide 3 to both sides:
x=30
The length would be 16, the width would be 9
8 x 6 = 48 because you just add a 1
