Answer:
Lines m and n are parallel because of the corresponding angles postulate.
Step-by-step explanation:
Corresponding Angles Postulate. The Corresponding Angles Postulate states that, when two parallel lines are cut by a transversal , the resulting corresponding angles are congruent .
For ADC you just add those two numbers. your answer would be D) 131
Hello there! :)
The Distributive property states:
a(b+c)=ab+ac
So, we know what a is. It's 5.
b=3
c=0.4
5(3+0.4)
5*3+5*0.4
15+0.2
15.2
Hope it helps!

Answer:
$60
Step-by-step explanation:
2 T-shirts = $15
Longer version
15/2 = $7.50
1 T- shirt = $7.50
7.50*8 = $60
Short version
2 T-shirts = $15
bought 8 so 8/2 = 4
4*15= 60
We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too
