Answer:
27
Step-by-step explanation:
3/1=x/9
cross multiply, or its just a ratio actually. 1:3 is equal to 9:27
So first we would convert 4 1/2 foot lengths into a decimal.
4.5 feet
Now we divide 25 by 4.5
25 ÷ 4.5 = 5.5
So Yancy can cut the board into five 4 1/2 foot lengths because the question says how many can he cut.
7+ 3x= -8
-8-7=-15
-15 divided by 3= -5
-5 is the answer
I believe that the answer is 25
