4^x=2×2^x=2×7=14
4^x-1=14-1=13
Answer:
C
Step-by-step explanation:
Step 1: Translate word to math
"Five" = 5
"times" means multiplication
"a number" = <em>n</em>
"plus" means addition
"3" = 3
"is" means equal
"12" = 12
Step 2: Set up equation (combine)
5n + 3 = 12
It would be 7.5/60 which equals .125
11.05 inches.
EXPLANATION:
Firstly, lets see the unit rate for how many inches per minute.
5.2 divided by 8 is 0.65 inches every minute.
Now since there is 17 mins, simply do 0.65 inches per min x 17 mins.
11.05 inches.
Hope this helps!
