Answer:
Step-by-step explanation:
Note that one equation has -2y and the other has +2y. The fastest solution is to add the equations together. The two terms will cancel out, eliminating the y terms.
A and C are complementary
B is supplementary
Step one. create a common denominator.
ex. 15
walnuts = 10/15 dried fruit= 9/15
so if you had 15/15 pounds of dried fruit you would need 16/15 pounds of walnuts
which is 1 1/15 pounds of walnuts
As soon as I see the word "Which ...", I know that there's a list of choices that
goes along with this question, but you decided not to share them. So there's
no way for me to help you choose the correct one.
In order to form a proportion with 3/4, you need another fraction (or ratio) that's
equal to 3/4 . Look for a fraction whose numerator is 3/4 of its denominator.
Here are a few examples:
-- 6 / 8
-- 24 / 32
-- 300 / 400
-- 12 million / 16 million
-- 3x / 4x
-- 15abc / 20abc
-- 3(x+y+z) / 4(x+y+z)
