7th grade math plz help

mina [271]

Answer:

x = 3

y = 3/2

Step-by-step explanation:

look at the hangers to form an equation:

x + x + x + 3 + 3 + 3 = x + x + y + y + y + y

simplify

3x + 3 = 2x + 4y

x + 3 = 4y

x = 4y - 3

you also know that

x + x = y + y + y + y

2x = 4y

substitute x = 4y - 3 into this equation ^

2x = 4y

2(4y - 3) = 4y

8y - 6 = 4y

4y = 6

y = 6/4

y = 3/2

2x = 4y

2x = 12/2

2x = 6

x = 3

pishuonlain [190]

Answer:

It would get <u>20</u> complete turns.

Step-by-step explanation:

Given:

The lead of a screw is the distance that the screw advances in a straight line when the screw is turned 1 complete turn. If a screw is 2 1/2 inches long and has a lead of 1/8 inch,

Now, to find complete turns.

Length of screw = $2\frac{1}{2}=\frac{5}{2}=2.5\ inch$

Lead of screw = $\frac{1}{8} =0.125\ inch.$

As, given the screw advances in a straight line when the screw is turned 1 complete turn.

Now, to get the number of complete turns it would divide length of screw by lead of screw:

$2.5\div 0.125\\\\=\frac{2.5}{0.125}\\\\=20.$

Therefore, it would get 20 complete turns.
