Instead of using an = sign we use

becuase its less than or equal to 100 dollars.
The equation of the line is y=10x+7
sub in 100 for y and the inequallity sign
10x+7

100
solve so x is isolated
10x

93
x

9.3
technically the answer is 9 because you cant buy a fraction of a CD
Answer:
If it's a straight line it's linear, if it curves it's non-linear.
Step-by-step explanation:
Assuming that a “circle graph” is a pie chart, the way of solving is this:
The degree of the angle of that pie section is relative to the entire circle just as the number of pyramids are to the number of total building blocks.
The number of pyramids out of the total is 30/150, or 1/5 (20%). This means that the angle of the section will be 1/5 the total angle measurement of the circle.
There are 360 degrees in a circle, and one fifth of this is 72 (360/5). Your answer is C.
