Answer:
x=5
Step-by-step explanation:
cross multiply
45=9x
solve for x by dividing 9 to get x alone
5=x

Answer:
r=20
Step-by-step explanation:
since the angle and sum of a straight line is equal to 180, you structure an equation:
180=105+(4r-5)
solve for r
180=100+4r
80=4r
20=r
check answer
4r-5 4(20)-5
80-5
75+105=180
Well if you know what a -X graph looks like (a diagonal line that goes from the top left to the bottom right, reading the graph from left to right). The answer is simply everything under that line. However, in this case, it also includes the space that the line is in itself. This is because it's less than OR equal to -x
