Answer: 7x + 4 y = 2
9x - 4y= 30
-------------------
16x / = 32
x= 32:16
x=2
Step-by-step explanation: 7x+4y=2
7*2 + 4y=2
14 +4y=2
4y= 2-14
4y= -12
y= -12 : 4
y= - 3
So you have 5/2
you are trying to figure out how many times you can make a whole out of 5/2
so your answer is 2.5 or 2 1/2 which is 2 wholes and 1/2
The lines are parallel.
Theorem: If two parallel lines are cut by a transversal, then same side interior angles are supplementary.
The angles measuring 16x + 4 and 80 are supplementary, so thjeir measures add to 180.
16x + 4 + 80 = 180
16x + 84 = 180
16x = 96
x = 6
Answer: A - 6
