Answer:
3
Step-by-step explanation:
(2x +1)/8 - (x-1)/3 = 5/24
multiple the 2x+1/8 by 3 and multiple (x-1)/3 by 8 then add them up
6x+3/24 - 8x-8/24 ➡ 6x-8x+11/24 = 5/24
➡ -2x+11 = 5
➡ -2x = 5-11
➡ x = 3

To find the area of all of the figures, all you need to do is base x height or the length x width.
Your answers for 1-6 are all correct.
For 7-9, remember that the area is the length times the width.
7) length x width, 42 x 30=1260
8) 17 x 22= 374
9) Since the length and width are the same in a square just multiply the side by itself. 2.7 x 2.7= 7.29
Hope this helps.
Answer:
Step-by-step explanation:
If all were dimes, the total would be $1.30. It is $0.75 more than that.

$0.75/$0.15 = 5
quarters.
Kevin has 8 dimes and 5 quarters in change.

To do this you have to round the 3. It is the same things as asking to round to the ones place.
To the right of the 3, is a 1. Since this digit is not bigger than a 5, the 3 stays the same.
Your answer is 3
