(PLEASE ANSWER ASAP I NEED HELP IM FR SO BAD AT FRACTIONS BUT PLEASE EXPLAIN ASWELL

1 1/4

Step-by-step explanation:

okay so to make 1 blanket she needs 4 1/2 yards of wool

the goal here is to add the fractions then subtract from the 4 1/2 to see how much more she needs.

STEP 1:

turn the fractions into mixed numbers

STEP 2:

next you have to find the least common multiple.(in this case 4) now we convert them(3x2 and 2x2)6/4 and since the second one is already 4 it stays as 9/4.

STEP 3: add 6/4 and 9/4= 15/4 then turn it into an improper fraction, 4 goes into 15 3 times with 1 left over so 3 1/4

STEP 4: subtract 4 1/2 and 3 1/4

once again convert to mixed numbers, subtract the numerators then change it back to an Improper fraction.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
