7-5.5=1.5

2×1.5=3
so 7 when both drop leafs are up
7-3=4
There's your answer

The length of the table when both leaves are folded up is 7 ft.

The length of the table when one of the leaves are folded up is 5.5 ft.


So if you do:

7 - 5.5 = 1.5

1.5 ft is the length of one of the leaves (remember the two drop leaves are the same size)


How long is the table when no leaves are folded up?

One leaf is 1.5 ft.

Since there are two leaves, the total length of the leaves is 3 ft.


7 - 3 = 4  

[7 is the length of the table when both of the leaves are folded up, 3 is the length of both of the leaves]

4 ft is the length of the table when no leaves are folded up

Express in the form n:1 give n as a decimal 21:12
Makovka662 [10]

1.75:1 which is similar to n:1 where n=1.75

<u>Step-by-step explanation:</u>

Here we have to Express in the form n:1 give n as a decimal 21:12 . Let's find out:

Given ratio as 21:12 . Let's convert it into n:1 , where n is decimal

⇒ 21:12

⇒ \frac{21}{12}

⇒ \frac{3(7)}{3(4)}

⇒ \frac{7}{4}

⇒ \frac{\frac{7}{4}}{\frac{4}{4}}                      { dividing denominator & numerator by 4 }

⇒ \frac{\frac{7}{4}}{1}

⇒ \frac{1.75}{1}

⇒ 1.75:1 which is similar to n:1 where n=1.75

Can you please help for 10 points
VARVARA [1.3K]

Hello!

First of all, we can see that our y-intercept is 0. As you can see, for every 1 x value, we have 3 y values. We divide, giving us a slope of 3.

Therefore, our equation is y=3x.

I hope this helps!
