The water temperature at the beach started at 82 degrees, and it is rising 0.6 degrees each hour. if the water temperature is now 85 degrees, write and solve an equation to find h, the number of hours that have passed.

5 hours

Step-by-step explanation:

The initial temperature is

The rate at which it is rising is each hour.

For h hours, the temperature at the beach is modeled by:

if the temperature is 85 degrees, then we substitute ans solve for h

Therefore 5 hours have passed

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.
