B. Set the sum of 7 and 24 equal to the sum of 8 and x, and then solve for x.
C. Set the product of 7 and 8 equal to the product of 24 and x, and then solve for x. D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Respuesta :

answer Choice D this is what is known as cross multiply

Answer:

Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Step-by-step explanation:

We have to determine how we can solve for x in the proportion:

7/8=x/24

Multiplying both sides by 8×24,we get

[tex]\dfrac{7}{8}\times 8\times 24=\dfrac{x}{24}\times 8\times 24[/tex]

i.e. 7×24=x×8

As we can see, we have to set the product of 7 and 24 equal to the product of 8 and x and then solve for x

Hence, Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.
