If 3(c + d) = 5, what is the value of c + d ?


Question

If 3(c + d) = 5, what is the value of c + d ?

Options

A)
\(\frac{3}{5}\)
B)
\(\frac{5}{3}\)
C)
3
D)
5

The correct answer is B.

Explanation:

Choice B is correct. The value of c + d can be found by dividing both sides of the given equation by 3. This yields c + d = \(\frac{5}{3}\). 

Choice A is incorrect. If the value of c + d is \(\frac{3}{5}\), then 3 × \(\frac{3}{5}\) = 5; however, \(\frac{9}{5}\) is not equal to 5. Choice C is incorrect. If the value of c + d is 3, then 3 × 3 = 5; however, 9 is not equal to 5. Choice D is incorrect. If the value of c + d is 5, then 3 × 5 = 5; however, 15 is not equal to 5.
