It takes esther 12 minutes to ride a roller
coaster four times. write an equation to represent
the proportional relationship between the number
of rides and the total amount of time.

7p=14 so then you would divide by p=2

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
