Answer:
108
Step-by-step explanation:
65+110+87=252
360(Total angle of quadrilaterals)-252=108
Is there a grid that came with the problem?
A linear equation can be represented by:
y = mx + b
Where m = slope, and b = y intercept.
The slope is a rate of change, so our slope is $150.
The y intercept is the point where the equation crosses the y axis, or the "initial amount" in this case $500.
So our equation will be:
y = 150x + 500.

2(5+c)=3(5-c)
solve for c
10+2c=15-3c
5c=5
c=1</span>
