Answer:
Number of hours= 48 hours
Step-by-step explanation:
Giving the following information:
Hourly rate= $7.25
Total earned= $348
<u>To calculate the number of hours worked, we need to use the following formula:</u>
Total earned= hourly rate*number of hours
number of hours= total earned / hourly rate
number of hours= 348 / 7.25
number of hours= 48 hours

Answer:
x = 14 is an extraneous solution
Step-by-step explanation:
Divide both sides by 4.
Square both sides.
Since we squared both sides, we much check for extraneous solutions because the process of squaring both sides can introduce extraneous solutions.
Check x = 14:
16 = -16 is a false statement, so the solution we found, x = 14, is an extraneous solution.
Answer:
8 44/45
Step-by-step explanation:
Find the LCM of 9 and 5, which is 45.
Then, set 7/9 with a denominator as 45, so it's 35/45.
Do the same for 1/5, so it's 9/45.
Add 3 + 5 + 35/45 + 9/45 to get 8 44/45.
