ANSWER
C. 35 men
EXPLANATION
Let m represent the number of men needed and d represent the number of days.
From the question,the number of men needed varies inversely to the time needed to complete the project.
We can write the inverse variation equation.
where k is the constant of variation.
When m=28, d =90.
We substitute these values into the variation equation to determine the value of k.
Now the equation becomes:
When d=72,
Therefore he needs to have 35 men working.
To find the average, find the mean: add all the numbers together and divide by the number there is.
First add all the numbers together:
39 + 43 + 28 + 36 + 29 = 175
Next, divide 175 (the total) by 5 (because there are 5 numbers)
175/5 = 35
35 is your average.
hope this helps

Answer:
x =29
x+6 =35
4x = 116
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+ (4x) + (x+6) = 180
Combine like terms
6x+6 = 180
Subtract 6 from each side
6x+6-6 = 180-8
6x = 174
Divide each side by 6
6x/6 = 174/6
x =29
x+6 = 29+6 = 35
4x = 29*4 =116
