We have: 2/25= 24/?
Cross multiply:
2*?= 25*24
⇒ 2*?= 600
⇒ ?= 600/2
⇒ ?= 300
The length of the window is 300 ft~
You will need to use the distributive property of multiplication over addition to solve this problem.
2w+10+4w=12+w
combine like terms using the associative property
6w+10=12+w
solve the equation
6w+10-10=12-10+w
6w÷6=2+w÷6
w=2+w/6
