Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice
substitution, elimination, matrices, etc
Answer:
B). 37.68 feet.
Step-by-step explanation:
Circumference = diameter * π
= 12 * π
= 37.68 feet.
Answer: The point (0,0)
This point is also known as the origin
The reason why is because every direct variation equation is of the form y = k*x
where k is some fixed number
If we plugged in x = 0 it leads to y = k*x = k*0 = 0. So (x,y) = (0,0)
4.50 is 450 percent
because it is greater than 1, we know it is more than 100%
