A park fountain sprayed 20 gallons of water in 1/2 an hour, then was turned off for awhile. When it was turned back on, it sprayed 30 gallons in 3/4 of an hour. Explain how you know that the fountain sprayed water at the same rate both times it was on.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

the answer is $42.96

step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
