Answer:
Good job they are all right!
Step-by-step explanation:
Hello,
I hope so far you and your family are staying safe and healthy!
We need to solve this step by step.
The college student has $700 in their account. But then she spends $165 on books from that money. So we need to Subtract that.
700 - 165 =535
However, later on, she deposits $190 to the same account. So we need to take the remain we had and add it to the new amount.
535 + 190 = 725
Thus,
There are $725 in the account.
I wish you all the best!

Step-by-step explanation:
im sorry if its wrong,its been a while since i did percentages
The formula for a rectangle's perimeter is
P = 2l + 2w
We know the length is 2 ft greater than thrice the width, so 2l becomes:
3w + 2ft + 3w + 2ft
Substitute.
P = 3w + 2ft + 3w + 2ft + 2w
Add like terms.
P = 8w + 4ft
Substitute P.
84 ft = 8w + 4ft
Subtract 4 ft from both sides to eliminate. (Property of equality)
84 ft - 4ft = 8w + 4ft - 4ft
80 ft = 8w
Divide 8 on both sides to isolate w.
80 ft / 8 = 8w / 8
10 ft = w
We have the value of w, now look for the l which we know is 2 feet more than thrice the value of w.
l = 10 ft × 3 + 2 ft
l = 30 ft + 2 ft
l = 32 ft
Therefore, the length and the width of the rectangle is 10 ft (w) and 32 ft (l).
Check:
84 ft = (2) (10 ft) + (2) (32 ft)
84 ft = 20 ft + 64 ft
84 ft = 84 ft ✔
