I am guessing cindy is standing inside the shadow of the flagpole. So the answer would be 12.5. To answer the question you have to set up proportions. 12.5/5=x/5, so you would cross multiply 12.5 and 5 then 5 and x so 62.5=5x then divide by 5 for 12.5.

I don't want to give you the answer so here is a thorough explanation and an answer if you want it. Set this up as a proportion. Set it up as 5/5=x/12.5. Then multiply 5 by x to get 5x and 12.5 by 5. Once you have this answer, divide it by five to isolate the x. Once you have finished this, you have your answer.

I got the answer 12.5. Make sure you check this so you understand how to solve these kinds of problems.

The sum of two numbers is x. If one of the numbers is 12, what is the other ?

Vlad1618 [11]

If the sum of two numbers is x

Then the equation is like this:

a+b = x

Then it says one of the number is 12. Change either a or b into 12

12 + b =x

If we want to find the other number, we need the make it into the subject

b = x - 12

Hope that help.

A rancher wants to fence in an area of 1000000 square feet in a rectangular field and then divide it in half with a fence down t

frosja888 [35]

The shortest length of the fence used by the rancher in a rectangular field of 1000000 square feet is 4899 ft.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle is a region enclosed in four corners where two opposite sides are equal. The area of the rectangle is mathematically expressed as:

Area of a rectangle = length(x) × breath(y)

1000000 sq.ft = (x) × (y) ---- (1)

However, to determine the fencing, we have:

Length of fencing = 2x + 2y
