Answer:
Kayla sold 90 boxes of cookies.
Step-by-step explanation:
let's have X be the number of boxes Kayla sold.
x⇒100%

Find x,
x=100/20 × 18
x=90
We can’t answer this question without more info. It’s clearly a multiple choice question, so you need to provide the answers.
Well if you write the statement as an equation then that will get you
3*x^2 = 12x
Now we just solve. You can divide both sides by 3x and that gives you x = 4
She can use 12 jewels for each pair of jeans. In fact, using 12 jewels per jeans implies that she will use jewels. The two remaining jewels can't be used on any pair of jeans, otherwise she wouldn't use the same number of jewels for each jeans.
This derives from the fact that, if you divide 50 by 4, you get a result of 12 with a remainder of 2.
Set up a proportion.
3/6 = 5.5 / x Cross multiply
3x = 6*5.5
3x = 33 Divide by 3
x = 33/3
x = 11
The length of x is 11.
