Answer: 4
<u>Step-by-step explanation:</u>
Let P represent Pete's age today. Let C represent Claire's age today.
2 years ago: P - 2 = 3(C - 2) ⇒ P - 2 = 3C - 6 ⇒ P = 3C - 4
4 years ago: P - 4 = 4(C - 4) ⇒ P - 4 = 4C - 16 ⇒ P = 4C - 12
Use substitution to solve the system above:
3C - 4 = 4C - 12
- 4 = C - 12
8 = C
Plug in the C-value above into one of the equations to solve for P:
P = 3C - 4
= 3(8) - 4
= 24 - 4
= 20
So, Pete is 20 yrs old today and Claire is 8 years old today
When will Pete be twice as old as Claire?
20 + x = 2(8 + x)
20 + x = 16 + 2x
20 = 16 + x
4 = x
Their ages will have a 2:1 ratio in 4 years.
In a trapezoid, two opposite sides are parallel and are called bases.
In this trapezoid, the top and bottom sides are parallel and are the bases.
The right side that intersects both bases is a transversal.
When parallel lines are cut by a transversal, same-side interior angles are supplementary. The measures of supplementary angles add to 180 deg.
x + 72 = 180
x = 180 - 72
x = 108 deg
Answer:
C.
Step-by-step explanation:
because it is x-8, it will shift to the right because it is always the opposite of the symbol. +3 refers to the points going up
