Answer:
24 and 48
Today, the son is 24 years old, and the father is 48 years old.
Step-by-step explanation:
(x - 10) + (2x - 10) = 52
3x + 20 = 52
3x = 72
x = 24
The father is 2 times his son's age.
2x
= 2(24)
= 48
So, the son is 24 and the father is 48.
10 years ago, son was 14 and father was 38, if added, this adds up to 52, so we know our calculations are correct.
Selection B is the best choice.

Answer:
70.69
Step-by-step explanation:
46 2/3 divided by 2/3
46.66 divided by 0.66
The anwser is 70.69
If the cook makes twice as much beef then the number of hamburgers would be two times larger which would be 141.39.
Half as much beef would be 70.69 divided by two which is 35.34.
s = 2(lw + lh + wh)
Divide each side by 2 : s/2 = lw + lh + wh
Subtract 'lh' from each side: s/2 - lh = lw + wh
Combine the 'w' terms: s/2 - lh = w(l + h)
Divide each side by (l + h): (s/2 - lh) / (l + h) = w
