I found that because i divided 130.50 by 4.5. =)
Hope that helped
Rewritten: 4(5.75 + 4.25)
solved: 4(10) = 40
explanation: it was easier this way because we did not have to work with decimals
Answer:
4 vests
Step-by-step explanation:
Larry has 9 yards of fabric, in which 2 are needed to make a vest.
Divide 9 with 2: 9/2 = 4.5
However, note that you cannot have half a vest, so you must round down.
4.5 becomes 4.
4 vests is the maximum Larry can make with 9 yards of fabric.

14x+2y=6 (1)
-7x-2y= -13 (2)
Multiply (2) by 2, we have:
-14x-4y= -26 (3)
Take (1)+(3), we can solve and get x= -1, y= 10~
