Question

7,200 / 80 = (7,200 / x) / x

What is the missing value of x in the equation?

A) 2
B) 4
C) √20
D) 2√20

Answer 1

To find the missing value of x in the equation 7200 / 80 = (7200 / x) / x, we can solve for x algebraically. By cross multiplying, we get 7200 = 90x. Solve for x by dividing 7200 by 90, resulting in x = 80.

Step-by-step explanation:

To find the missing value of x in the equation 7200 / 80 = (7200 / x) / x, we can solve for x algebraically.

First, simplify the left side of the equation by dividing 7200 by 80, which equals 90.

Next, simplify the right side of the equation by dividing 7200 by x, which gives us (7200 / x).

Finally, set up an equation by dividing (7200 / x) by x. So, the equation becomes (7200 / x) / x = 90 / x. By cross multiplying, we get 7200 = 90x. Solve for x by dividing 7200 by 90, resulting in x = 80.
