Answer:
whole milk 4 ---------------- 32 ounces
skim milk 0 ---------------- x ounces
Mixture 2.5 ---------------- 32 + x ounces
4*32+0x =2.5(32 +x)
128+0x= 80+2.5 x
0 x + -2.5 x = 80 - -128
-2.5 x = -48
/ -2.5
x = 19.2
19.2 ounces of 0 % fat skim milk
Answer: They won 60 games and lost 100 games
Explanation: To find this, first, we need to keep in mind that for every 8 games they played, they won 3, and lost 5. With this, we need to do 160/8 and we will get 20. Finally, to find # of games won, we will do 3(20) which is 60, and to find # of games lost, we will do 5(20) which is 100. Hope this helped!
