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.
Answer:
-4x+8-15/x+2
Step-by-step explanation:
divide
-4x+8x+1/x+2
divide that
-4x+8+-15/x+2
simplify
-4x+8-15/x+2

<u>formula: </u>
(a+b)^2
= a^2+2ab+b^2
Here, we have x^2 (as in a^2)
and -6x (as in 2ab), which, we're missing the b^2
(I'm not really sure how to describe this but bare with me)
-6/2 (-6 is from the -6x) = -3 (the b)
-3^2 = -3*-3 which is equal to 9 (positive 9)
Writing it out -
x^2-6x+9 = -5
- Addition of inequality -
Since we add 9 to the left side, we have to add 9 to the right side; which gives us:
x^2-6x+9=4
Next, lets put the x^2-6x+9 as in (a+b)^2:
(x-3)^2 = 4
<em>Then let's do the square root of equality (square rooting both sides) :</em>
<u>x-3 = 2</u>
<em>Finally lets add 3 to both sides</em>
<u>x = 5</u>
THE ANSWER IS <u><em>x=5</em></u>
