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)
Answer:

Using proportions, it is found that 66 people in the survey worked on election day.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
For this problem, the amounts of people who worked are:
Hence the total amount is given by:
0.64 x 50 + 0.4 x 85 = 66.
66 people in the survey worked on election day.
