Let y represent Tim's age and let x represent Chris's age.
y=3x
y=x+14
Set the two equations equal to each other:
3x=x+14
Subtract the x from the one side to get it on the other side.
2x=14
Divide by 2 on both sides
14/2=7
x=7
Plug it back in and see if it works:
y=3(7)=21
Other equation:
7+14=21
x=7
y=21

Answer:
(a) Theorem 9
Step-by-step explanation:
Any of the given theorems can be used to prove lines are parallel. We need to find the one that is applicable to the given geometry.
<h3>Analysis</h3>
The marked angles are between the parallel lines (interior) and on opposite sides of the transversal (alternate).
Theorem 9 applies to congruent alternate interior angles.
The formula to solve for the volume (V) of a rectangular prism is,
V = L x W x H
where L is the length, W is width, and H the height or depth.
Substituting the known dimensions on the equation above,
V = (4 in) x (9 in) x (2.2 in) = 79.2 in^3
Thus, the volume of the cake pan is 79.2 in^3.
