By using the principles of inverse variation, it is determined that it would take 20 workers 38 days to build a similar house.
The problem is an example of inverse variation, where the amount of time (days) to build a house decreases if the number of workers increases. In this specific scenario, one house was built in 76 days by 10 workers. We can represent the inverse variation relationship with the equation: days * workers = constant.
Using the given data, the constant can be calculated by multiplying the days by the number of workers, hence:
constant = 76 days * 10 workers = 760
To find the number of days it would take for 20 workers to build the house, we divide the constant by the number of workers:
days = constant / workers = 760 / 20 = 38 days
This means that it would take 20 workers 38 days to build a similar house.

B. 7.5
C. 10.8
D 12.4
Answer:
7.5
Step-by-step explanation:
0.2(6r-5) =8 Distribute.
0.2(6r)-0.2 (5) =8 Simplify.
1.2r−1 =8 Add 1 to each side.
1.2r =9 Divide each side by 1.2.
1.2r/1.2 =9/1.2 Simplify.
r =7.5

A.x = 10
B. x = 9
C.x = 11
D.x = 8
You can find the value of x in the function f(x) = 3x - 7 when f(x) = 20 by isolating x in the equation. This process leads to an answer of x = 9.
To solve this problem, you need to substitute the given function's value f(x)=20 into the equation and solve for x.
So, you have the equation 3x-7=20. In the next step, you add 7 to both sides to isolate 3x on one side, which gives you 3x=27.
Finally, divide both sides by 3 to find the value of x. Doing so, you get x = 27/3, which simplifies to x = 9.
Therefore, when f(x) = 20, the value of x is 9, which matches answer option B.
