That's correct, because I learned it in math already
Part A
Distribute the one-half.
1.24g + 0.87m + 0.98z
Part B
(29.68 - x) + 14.45
Or simplified to 44.13 - x
Part C
a = number of times at the store
b = gloves' price
c = hat's price
This is applying the formula

We have a slight problem, though, because we are measuring rate in miles per hour, and we are measuring time in minutes. To make this problem solvable, we need to convert to either miles per minute or convert the time to hours. I'm going to convert the 15 minutes into hours:

Now that all of the units match, we have:

You can finish from there I'm sure.
Answer:
-n-10
Step-by-step explanation:
(n-8)-(2n+2)
n-8-(2n+2)
n-8-2n-2
-n-8-2
-n-10
