Yancy has a board 25 feet long. He wants to cut the board into 4 1/2 foot lengths. Into how many 4 1/2 foot lengths can he cut i

seropon [69]

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.

What is the solution to this system of equations?

maksim [4K]

Answer:x=3 y=1/2

Step-by-step explanation:

x+2y=4

2x-2y=5

Add both equations together

x+2x+2y-2y=4+5

3x+0=9

3x=9

Divide both sides by 3

3x/3=9/3

x=3

Substitute x=3 in x+2y=4

x+2y=4

3+2y=4

Collect like terms

2y=4-3

2y=1

Divide both sides by 2

2y/2=1/2

y=1/2
