Final answer:

The given problem seems to have a typo, but using the proportion (4/3 = x/10), cross multiplication yields x approximately equal to 13.33, which does not match the provided answer choices. Clarification is necessary to provide an accurate solution.

Step-by-step explanation:

The given proportion is ( 43 = x10 ), and we need to find the equation that can be used to solve for x. To do this, we set up a proportion where 43 is equal to 10 times the unknown value x. We can then cross multiply to solve for x as follows: 43 = 10x, which can be rearranged to x = 43/10. If we simplify this, we get x = 4.3. However, the options provided appear to be a typo as they do not include 4.3. Therefore, assuming that the correct proportion was supposed to be ( 4/3 = x/10 ), we would cross multiply to get 4*10 = 3x, which results in 40 = 3x. We can then divide both sides by 3 to solve for x, which would give us x = 40/3 or approximately 13.33, not matching exactly with any of the options provided in the question. Further clarification on the initial proportion is needed to provide a conclusive answer.
