5x+3x=90+30
8x=120
(1/8) (8x) = (1/8) (120)
x=15
m<JAH= 3(15)=45
m<HAG= 5(15)=75
and the first one is
<KAE and <EAF are adjacent angles whose measurements are equal to
<KAF; <KAF and <JAG are vertical angles and are of equal measurement.

Answer:
(C) (2, -2)
Step-by-step explanation:
Given the linear equation: 
A second linear equation is given by the table:

Clearly, this is a graph of y=-x as each y-value is a negative of its x-value.
Therefore if:

Recall: y=-x
Therefore: y= -2
Therefore, a solution to the system of equations is (2, -2)
Answer:
$21
Step-by-step explanation:
multiply 1.75 times 4, which is 7
then multiply 7 times 3, which is 21
