t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
If a number in parenthesis is directly next to a number without, then the two numbers need multiplied.
-12(5/6)(-2/15) is an example of a double multiplication. But we'll multiply -12 and 5/6 first, then multiply the product by -2/15.
-12x5/6=14 2/5
14 2/5x-2/15=-1 23/25

Answer:
"The Quadratic Equation, Formula, & Discriminant. If ax² + bx + c = 0 then x = . The first equation is called the general form of a quadratic equation. The second equation is called the Quadratic Formula because it states the solution -- provides a formula for computing the simplified answer(s) by using the values of the first equation."
