Question

Why is X−8 a solution to the proportion 1922−22?

A. Because 192 divided by 32 is equal to 6.
B. Because 192 divided by 36 is equal to 6.
C. Because if you substitute 6 into the equation for x and cross multiply, you get 1,152−1,152.
D. Because if you substitute 6 into the equation for x and cross multiply, you get 1,298−1,298.

Answer 1

The original question is not clear, and seems to contain typos. However, by applying the correct method to solve a proportion through cross multiplication, as shown in a clear example, we can demonstrate how to find the solution to a proportional equation.

Step-by-step explanation:

The question seems to misunderstand the calculations involved in determining whether X-8 is a solution to a proportion. However, using the information provided, we can deduce a correct approach to solving a proportion. If we consider the proportion 1922-22, which seems to be a typo, and try to interpret it as a coefficient question, we still encounter issues because it's not properly formatted as a proportion.

Using given information about variables, one correct way to solve a proportion is demonstrated in an example. First, set up a proportion such as 1 foot/12 inches = 12 feet/x inches. Next, cross multiply to solve for x. This gives us 1*x = 12*12. By solving this, we find that x = 144 inches. Such a step-by-step approach helps to clarify how to cross multiply and solve proportional relationships correctly.
