Answer:
4:29
Step-by-step explanation:
First we need to make the time an easier number to work with
so we subtract 14 from 45. That is how we get 31.
Next, we know there are 60 minutes in a hour so we do 60-31 to get 29.

24,717.
What you have to do is subtract 38,773-14,056 and then the answer would be 24,717. So all together 24,717 must be added to result in the sum of 38,773.
14,056+24,717=38,773.
Answer:
7c^2
Step-by-step explanation:
I'm assuming you meant "9c^2 - 4c^2 + 2c^2." This comes to:
(9 - 4 + 2)*c^2, or 7c^2.
10 times a number y
3 subtracted from a number x
12 times a number n

So first, just calculate how much more she needs to save to get the guitar.
253.77 - 136.27 = 117.5
And now just find how many weeks she needs to save up for.
117.5 / 23.5 = 5
So she needs to save up for 5 more weeks.
