Step-by-step explanation:
2x + 1 = 16
2x = 15 (subtract 1 on both sides)
x = 7.5 (divide 2 om both sides)
Since 7.5 is not an integer, (a) is No.
However 7.5 is rational, therefore (b) is Yes.
I think what you are looking for is 5x=300 therefore x=60 so at 60cars he would start to make more.
Answer:
x
Step-by-step explanation:
The answer to

= x
Just solve the square roots and compare all four to see which one is the normalest
