Answer:
12
Step-by-step explanation:
Since they are parallel then
(7x - 8) + (11x - 28) = 180
18x - 36 = 180
18x = 216
x = 12
Answer:
14 years old
Explanation:
Use this system of equations if G=George and J=Jeannie:
G-12=J
50=(G+5)+(J+5)
So, change second equation becomes
40-G=J
Then use substitution:
G-12=40-G
2G=52
G=26
Then, to find Jeannie’s age, go back to one of the equations and substitute G.
26-12=J
So, J=14
Jeannie is currently 14 years old.
Answer:
16 and 32
Step-by-step explanation:
Answer:
41
Step-by-step explanation:
By transversal parallel lines theorem, x=41
P(-2) and P(3) is telling you to substitute the “x” in the equation for those two.
So P(-2)=(-2)^3 - (-2)^5 =24
and
P(3)= (3)^3 - (3)^5 = -216
hope this helps !
