Answer: see below
Step-by-step explanation:
|2x+5|=7
2x+5=±7 ⇔ since the absolutely value of any number is all positive, so the value in side can be either positive or negative
2x+5=7 or 2x+5=-7
2x=2 2x=-12
x=1 or x=-6
----------------------------------------
The product of the two solutions
1 × -6=-6

Answer:
$101.85
Step-by-step explanation:
Think of the two days as separate equations. They are added together to get a sum of the pay she will receive after the two days.
Equation
(4.5*10.5) + (5.2*10.5) = x (This just represents the unknown value)
Solve Through
(47.25) + (54.60) = x
47.25 + 54.60 = x
101.85 = x
