You can pack up to 10 1/5 pounds more stuff without going over
Area of one piece is 26.24cm ^2 or just 13.12cm
It would be answer choice A (10^5) because there are 5 10s in the problem
When you expand the equation, you will have
9x + 9=25 + x
Next you have to collect like terms
+x will go over the equality sign to become -x. The same applies to +9
9x - x=23 - 9
9x minus x is 8x
8x=14
Divide both sides by 8
x=14/8
You will have 1 6/8
6 is the remainder while 1 is the number of times 8 divided 14.
In decimal, it will be 1.75
Hope that helped. Good luck
