Answer:
1:4:12
Step-by-step explanation:
George = x
Alex = 12 + x
Carl = 3(12 + x) = 36 + 3x
x + 12 + x + 36 + 3x = 68
5x + 48 = 68
5x = 20
x = 4
George = x = 4
Alex = 12 + x = 12 + 4 = 16
Carl = 36 + 3x = 36 + 3(4) = 48
4:16:48 = 1:4:12
The ratio is 1:4:12.
Answer:
Step-by-step explanation:
a. 29/8 + 2(19/4) + 3(27/8) = 29/8 + 38/4 + 81/8 = 29/8 + 76/8 + 81/8 = 186/8 in.
b. 186/8 times 2 = 372/8 in
c. the shortest plane would be 27/8 and the largest would be 19/4 or 38/8.
If you subtract the two, you get 11/8. The difference is 11/8 in.
