let's firstly convert the mixed fractions to improper fractions and then add up all four days.

Answer:
125 feet below sea level or -125
Step-by-step explanation:
The answer would be
x² + 18x + 81 = 44 + 81
To complete the square, we look at the value of b (the coefficient of x). We take half of it, then square it; this is the number that gets added to both sides.
18/2 = 9; 9²=81
Therefore we add 81 to both sides.

<u>Answer:</u>
Donovan babysat for 7 hours on Saturday in order to earn $31.50.
Step-by-step explanation:
In order for you to answer your question, you'll need to use the cross product method:
$9 → 2 hours
$31.50 → X hours
<u>(2 × 31.50)</u> ÷ 9 = X hours
<u>63 ÷ 9</u> = X hours
<u>7 = X hours</u>
There you go! I really hope this helped, if there's anything just let me know! :)
