Stephen makes wooden shelves for his room he starts with a board that is 20 feet long.Stephen wants to make the shelves 3/4 foot

jek_recluse [69]

The number of shelves stephen can make is approximately 27

<h3><u>Solution:</u></h3>

Given that Stephen makes wooden shelves for his room

Stephen wants to make the shelves 3/4 foot long

He starts with a board that is 20 feet long

To find: number of shelves he can make

So the number of shelves stephen can make can make is found out by dividing 20 feet long board by 3/4 foot long

$\text {number of shelves }=\frac{\text { total length of board stephen has }}{\text { length of each board }}$

$\text {number of shelves }=\frac{20}{3 / 4}=\frac{20}{0.75}=26.6$

So the number of shelves stephen can make is approximately 27

If x=3m-4 and y=6-m, which of the following expresses y in terms of x

coldgirl [10]

Answer:

What you want to do is solve for m in whichever equation it's easier to so in, then substitute that in to the other equation. For instance:

X=3m-4

Y=6-m

Solve the 2nd equation to get m=6-y

Plug that into the first equation to get x=3(6-y)-4

X=18-3y-4

X-14=-3y

14-x=3y

Y=(14-x)/3
