<h3>
Answer: 7t + 12(86-t)</h3>
==========================================================
Explanation:
- t = number of hours she worked as a tutor
- 86-t = number of hours she worked as a waitress
The two expressions mentioned add to 86, to indicate the total number of hours for both jobs combined.
- 7t = amount earned as a tutor
- 12(86-t) = amount earned as a waitress
We multiply the number of hours by the wage per hour to get the amount earned per job.
Lastly, we add those two subtotals to get the grand total earned
7t + 12(86-t)
Optionally you can distribute the 12 through and combine like terms. I'll leave it like this because I think it's more descriptive to show the two amounts earned from each job.
If you wanted to simplify 7t+12(86-t), then you would get 1032-5t or -5t+1032

Answer:
If the perimeter is 200feet (two lengths and two widths) then one width+one length equals 100feet.
If the length is 10 feet longer than the width, then length = 55 feet, and width =45 feet
Therefore the area of the rectangle is 45x55 feet, which equals 2475 sq.ft
