Can someone give me the answers? : ))

X / 20 = 12/16

x / 20 = 3/4

4x = 60

x = 15

b. x/20 = 6/8

x/20 = 3/4  

as above x = 15

c.
They are the same because the ratios of all corresponding size of ssimilar triangles are the same.

You would have 15$ left

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
