Answer:
D
Step-by-step explanation:
First, remove parenthesis:
8(x + 30) = 8*x + 8*30 = 8x + 240
Then, add the 5 at the end:
8x + 240 + 5 = 8x + 245

Answer:
Each binder costs 30 cents or $0.30
Step-by-step explanation:
If Sarah's total was $9.05 and the binder costs 7.25 then in order to find the price of the folders you must subtract the cost of the binder (7.25) from the total (9.05) which leaves $1.80 as the amount she paid in total for 6 folders. Next, to find the amount spent per folder divide 1.80 by the number of folders which is 6 and your final answer should be 0.30.
9.25= 7.25+6x (next subtract 7.25 on both sides)
1.80=6x (next divide by six on both sides)
0.30=x
I believe C/12=pi which means the answer would be B.
