The ratio 20/10=5/n. What does n equal?
DIA [1.3K]
N is equal to 2.5

I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5

Or we can do this solution.

20          5
----  =    ----  ; do cross multiplication.  20n = 10(5)
10          n

20n = 50 ; to get n, divide both sides by 20.    20n / 20 = 50 / 20 = n = 2.50

Whichever way: 20/10 = 5/2.5

Cookies are on sale! Today each cookie costs $0.75 less than the normal price. Right now if you buy 7 of them it will only cost
Anestetic [448]
Let's say that the price of each normal cookie is n.
The equation would then be 7(n - .75)=2.80.
Use distributive property, getting 7n - 5.25=2.80.
Add 5.25 to each side of the equation, getting 7n=8.05. 
Divide 7 from both sides of the equation, getting n=1.15.
