Jess needs 4 ounces of cheese for every 10 ounces of meat in a recipe if she uses 30 ounces of meat how much cheese will she need? PLEASE ANSWER!

12 ounces of cheese

Step-by-step explanation:

Set the ratio of the ounces of cheese : meat (which is 4 : 10). If Jess uses 30 ounces of meat, all we need to do is compare the amounts to each other, using the variable x:

4 : 10

x : 30

We can see that there is 3 times the amount of meat required than there was in the original recipe. Because of this, all we need to do is multiply the ounces of cheese by 3. This leaves:

(4 : 10) * 3 = 12 : 30

When we look at the ratio we made (x : 30), we can see that x = 12.

Don't forget the units when answering the question!

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
