The answer seems to be D!!
Answer:
x = 30
Step-by-step explanation:
10% fat = 0.1x
x = the solution, what we want to find
120 grams of 20% fat = 0.2 * 120
What we want is mixture of 18%
So....
0.1x + 0.2 * 120 = 0.18 (x + 120)
Solve:
0.1x + 24 = 0.18 (x +120)
0.1x + 24 = 0.18x + 21.6
24 = 0.08x + 21.6
x = 30
Answer:
mean is 25.6
Step-by-step explanation:
add all numbers and divide by amount of numbers
Multiply 7 1/2 by 5 1/2 and get 41 and 1/4
now divide 41 1/4 by 1/2 and get 83..
83 would be your answer(I got a little confused so this might be wrong D:)
