Answer:
By giving reasons to the statements
Answer:
The answer to your question is the third choice 4 / (3d - 12)
Step-by-step explanation:
Data
length = (d -2 ) / (3d - 9)
width = 4/(d - 4)
height = (2d - 6)/(2d - 4)
Process
1.- Multiply the numerators
(d - 2)(4)(2d - 6) = 8(d - 2)(d - 3)
2.- Multiply the denominators
(3d - 9)(d - 4)(2d - 4) = 6(d - 2)(d - 4)(d - 3)
3.- Simplify
8(d - 2)(d - 3) / 6(d - 2)(d - 4)(d - 3)
8 / 6(d - 4)
Simplify 8/3 = 4/3
4/3(d - 4)
A.) 135 miles in 3 hours = 45 miles per hr
B.) 22 miles in 1 hour= 22 miles per hr
C.) 7.5 miles in 1/4 hour = 30 miles per hr
D.) 100/3 in 2/3 hour = About 49.9 mph
E.) 97.5 in 1.5 hours = 65 miles per hr
Simplified: 102/25
Mixed number: 4 2/25
