Answer 1

D is the answer because all you have to do is solve

Answer 2

Answer:

Option A is correct.

The expression which is equivalent to $\frac{1}{3}(5x+3y)+\frac{2}{5}y +7$ is, $\frac{5}{3}x + \frac{7}{5}y + 7$

Step-by-step explanation:

Given the expression: $\frac{1}{3}(5x+3y)+\frac{2}{5}y +7$

The distributive says that:

$a\cdot(b+c) = a\cdot b+ a\cdot c$

Apply distributive property on [1] we have;

$\frac{5}{3}x + y + \frac{2}{5}y + 7$

Like terms are those terms which have same variables to the same power.

Combine like terms, we have;

$\frac{5}{3}x + \frac{7}{5}y + 7$

Therefore, the expression which is equivalent to $\frac{1}{3}(5x+3y)+\frac{2}{5}y +7$ is, $\frac{5}{3}x + \frac{7}{5}y + 7$
