Answer:
Step-by-step explanation:
There's really nothing to solve here. Rather, you should describe what x≤100 represents.
To draw an appropriate graph, draw an x-axis, mark x=100 with a black dot, and then draw an arrow to the left from this dot. That's it. "All x less than or equal to 100."

Answer:
59
Step-by-step explanation:
We know that all the angles must add up to 180
so we have
38+2b-20+b-15=180
solve for b
3b+3=180
3b=177
b=59
(12+8)\ 5 + 15=19... this solution works because 12+8=20.. 20/5=4 and then 4+15=19
