Using a system of equations, it is found that Debbie worked 45 hours during the week.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount of hours worked by Juan.
- Variable y: Amount of hours worked by Debbie.
Juan and Debbie each earn 9 per hour at their "jobs", and earned a total of 765 for the week, hence:
9x + 9y = 765
Simplifying the expression by 9:
x + y = 85 -> x = 85 - y.
Debbie worked five hours more than juan during the week, hence:
y = x + 5.
Since x = 85 - y, we replace in the expression:
y = 85 - y + 5.
2y = 90.
y = 45.
Debbie worked 45 hours during the week.

ANSWER
3438
EXPLANATION:
<em>PARENTHESIS FIRST</em>
32 x 8 = 256
17 x 4 = 68
256 - 68 = 188
(<u>now the equation is, 6³ ÷ 4 + 2 x 9 (188))</u>
<u />
<em>EXPONENTS NEXT</em>
6³= 216
(<u>now the equation is, 216 ÷ 4 + 2 x 9 (188))</u>
<u />
<em>MULTIPLICATION AND DIVISION NEXT (left to right)</em>
216 ÷ 4 = 54
2 x 9 = 18
18 x 188 = 84
(<u>now the equation is, 54 + 3384)</u>
<u />
<em>LASTLY ADDITION AND SUBTRACTION (left to right)</em>
54 + 3384 = 3438
Ta-da!
