Answer:
$75
Step-by-step explanation:
To find out how much George's mom paid for the 6 tickets, first find the unit rate, that is cost per ticket.
The unit rate/constant of proportionality between cost of tickets (y) and number of tickets (x) can be calculated using the coordinates of any points on the graph.
Using (4, 50), this means that 4 tickets cost $50.
Unit rate/constant of proportionality = y/x = 50/4 = 12.5
This means a ticket costs $12.5.
Therefore, 6 tickets would cost:
6 tickets × $12.5 = $75.
George's mom paid $75 for the tickets?
-(1.5, -3)
think of the y axis intercepting the x axis at coordinates (0,0)
-they then said their point is 1.5 left of the y axis
-now all you have to do is to find another x value of that same distance (x,y)
Answer:
he is correct because 20% is the same thing as 1/5 amd 1/5 is the same thing as dividing by 5
Step-by-step explanation:
I’m not 100% sure but I think it’s -2
Answer:
16
Step-by-step explanation:
Use a special rule: BD^2=AD*DC (the squared height in right triangle drawn to hypotenuse is equal to the product of the parts of hypotenuse on which height divides the hypotenuse) 12^2=9*DC
DC=16
