Answer:
420 cars were tested
Step-by-step explanation:
55/100=231/x
55x= 23100
x=420
In order for the equation to be true, one of the factors on the left has to equal zero
So, 2x-3=0 or x-4=0 (the 3 on the left for multiplication doesn’t affect the possible answers for x)
Once you solve them, you conclude that x has to be 4 or 3/2.

Answer:
Simplify 2x - 4) + 7(x + 2).
9x + 6
9x - 4
09x - 6
= 9x+10
