Answer:
The answer is 1 1/4 or a.
Step-by-step explanation:
Basicallly percents are based of 100% so there is a 100% which would be a whole then there is only 25% and if you take 4 quarters and each quarter is 25 cents and there is 4 quarters in a whole that would be 1/4. You add the 1 whole and the 1/4 to get 1 1/4.

11.8
Step-by-step explanation:
I think it is subtracting fractions.
First you turn the fractions into decimals then subtract it. After, you turn the decimal to a fraction but i am having a hard time doing that... the decimals by the way is 12.5 and 0.7 according to converters
Multiply both sides of the second equation by 4. That will give you -4x in the second equation which when added to 4x of the first equation will eliminate x.
Second equation:
-x + 3y = 6
Multiply the second equation by 4 on both sides:
-4x + 12y = 26
