(10n-5)/(5)= 2n-1

10/5 = 2 and -5/5 =-1
and you get the answer
2n-1= 2n-1
The sum of 3 fifteens and 4 twos will be 45 +8 = 53

Answer:
8 units squared.
Step-by-step explanation:
Assuming the numbers are the length and width, we can use the formula for finding the area of the rectangle.
The area should be eight units squared.

Just do this 550+450=1000-120=880=750=1630 Now I assume that what you meant to say was what percent of the new balance was the last deposit made. So thats what Im going to be answering off of. We would need to take 1630-750=880 then 880/1630=.54 (rounded to the nearest hundredth) then we need to subtract 54 from one hundread because .54 is how much that the account overgoes the latest deposit making are final answer. That the last deposit that she mad accounted for 46% of the entire account. Enjoy!=)
