The two numbers are 80 and 4.
The quotient of 80 and 4 is 20: 80 ÷ 4 = 20
The sum of 80 and 4 is 84: 80 + 4 = 84
Step-by-step explanation:
Unit rate = 68 ÷ 8.5 = 8
8 1/2 = 8.5 hours

<h3>What is a linear equation?</h3>
A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
- An example of linear equation is y=mx + b. A polynomial equation of the first degree (such as x = 2y - 7)
- A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.
