Answer:
-11
Step-by-step explanation:
Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104
The measure of angles are 76 and 104
It is easy try to figure it.
If you did not figure it out the answer is
A. I think is 24 not sure.
B. I think it is 18 not sure.
16 model airplanes on his shelf
4 times as many model airplanes as model trains
let's denote the number of model trains as m
So,
m=16×4
m=64
Therefore,there are 64 model trains.
