Answer:
x = 23
Step-by-step explanation:
2x + 19 + 5x = 180
I say this because it is an angle that is equivalent to the one adjacent to 2x+19, which is on a straight line. That means it is equal to 180.
7x + 19 = 180
180 - 19 = 7x
161/7 = x
x = 23
The answer would be
4
5

Yes
A) 27, 81
b) -30,-15
c) -3, 1
d) -320, 1280
Well, if you just divide 4000 by 50, you can see that the answer will come out as:
<em><u>80
</u></em>~TO check: 80 multiplied by 50 would come out to the answer of 4,000.
