Answer:
6
Step-by-step explanation:
2 ft = 24in so 4 to 24 is times 6
3ft=36 in and 6 to 46 is times 6
x+y =27 sum of two numbers is 27
x=y+3 One of the numbers is three more than the other
substitute x=y+3 into the first equation
(y+3) + y = 27
combine like terms
2y + 3 = 27
subtract 3 from each side
2y = 24
divide by 2
y =12
x = y+3
x = 12+3
x =15
the two numbers are 12 and 15
![\frac{5}{8} y = -1](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B8%7D%20y%20%3D%20-1)
First, change
![\frac{5}{8} y](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B8%7D%20y)
to
![\frac{5y}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5y%7D%7B8%7D%20)
/ Your problem should look like:
Second, multiply both sides by 8. / Your problem should look like:
Third, divide both sides by 5. / Your problem should look like:
![y = -\frac{8}{5}](https://tex.z-dn.net/?f=y%20%3D%20%20-%5Cfrac%7B8%7D%7B5%7D%20)
Answer as fraction: y =
![- \frac{8}{5}](https://tex.z-dn.net/?f=-%20%5Cfrac%7B8%7D%7B5%7D%20)
Answer as decimal: -1.6
