w=5+l

336=l*(5+l)

MAVERICK [17]

Use distributive property: a(b + c) = ab + ac

1/3(9a + b) - 1/2(4a + 2b) = 3a + 1/3b - 2a - b = a - 2/3b

zzz [600]

Answer:

Mary is 8 and that Zane and Chase are both 4 years old.

Step-by-step explanation:

For this equation, we will say Mary = M, Zane = Z, and Chase = C.

We will now convert the word problem into equations.

$2m = z, 2c - 4 = z, c = 4$

Now I will solve the equations by putting C into the equation.

$2(4) = 8, 2(4) - 4 = 4, c = 4$

So we can see that Mary is 8 and that Zane and Chase are both 4 years old.
