Answer : C (24 - 6) ÷ 3
(almost 100% sure this is correct lol)
Answer is A because x+x+70=180 subtract 70 in 180 so 2x=110 110 divided by 2 is 55 so x=55
Answer: 4 cups of milk
=============================
Work Shown:
2 & 1/2 = 2 + 1/2 = 2+0.5 = 2.5
2.5 cups of milk makes 5 servings
x cups of milk makes 8 servings
Divide the cups of milk over the servings to get this proportion
2.5/5 = x/8
Cross multiply and solve for x
2.5/5 = x/8
2.5*8 = 5*x
20 = 5*x
5*x = 20
x = 20/5
x = 4
You need 4 cups of milk to make 8 servings
The sum of the polynomials will be:
(6s^2t-2st^2)+(4s^2t-3st^2)
=(6s^2t+4s^2t)+(-2st^2-3st^2)
=10s^2t-5st^2
Thus the answer is:10s^2t-5st^2
