Answer:

Joe is 9 years old

Step-by-step explanation:

We can start by creating two different equations, one for each fact that we know about their ages.

Say that J is Joe's age

Say that T is Tim's age

Our first equation would then be:

4J + 2T = 50

J - 2 = T

Now that we know that T is J - 2, we can plug that in to the first equation.

4J + 2(J - 2) = 50

We can simplify this equation to solve for J

4J + 2J - 4 = 50

6J = 54

J = 9

Joe is 9 years old

Kipish [7]

We are given

edge of cube =x

we know that formula for volume of cube

V=x^3

we are given

V=\frac{1}{8} cm^3

we can plug value

x^3=\frac{1}{8} cm^3

now, we can solve for x

\sqrt[3]{x^3} =\sqrt[3]{\frac{1}{8} cm^3 }

x=\frac{1}{2} cm............Answer
