Answer:
A) 
Step-by-step explanation:
We are trying to find how long it will take Carlos to have $500 TOTAL, so we need to subtract what he already has ($150) to get the value we want to divide by $25 to figure out how many months it will take him to save up the rest. The given answer above is just a simplified way of writing 
, if that makes more sense.
The answer is B. 3
It is the only value not attached to a variable, thus remaining constant.
I think you multiply length times width if not I am sorry. I think the answer is 30. Sorry if it isn’t
3/8=.375
.375 move the decimal two times to the right to make it a percent so it would be 37.5%
Since the x value can be changed to anything other than 4 (because then you would be dividing by 0 in x-4), the answer is: All real numbers except 4.
