This is a typical mixture problem where using a table is the best thing.
pints juice % juice = total % juice
juice A x .70 = .70x
juice B 60-x .95 = .95(60-x)
total 60 .75 = 60(.75)
The last row gives you a total that you need to use, so do that multiplication to get 45. You now to need to add the last columns together for rows 1 and 2 and set them equal to 45: .7x +.95(60-x) = 45. When you do that math, you'll get that x = 48. This means that you need 48 pints of juice A and 60-48 pints of juice B, which is 12 pints.
Answer:
x = 4
Step-by-step explanation:
divide both sides by 5- 2x + 5 = 13 subtract 5 from both sides
- 2x = 8 divide both sides by 2
- x = 4

Answer:
B. 37
Step-by-step explanation:
You first find the median of the entire set which is 46. Then find the median of the lower half of the set which is 27. Then find the median of higher part of the data set which is 64. Then you do 64-27=37.
Hope that helped a little bit :)
(a+10)+44=2a
a+54=2a
