Yes 678.05 is greater than 67.805 (because obviously 678 is greater than 67 right? ^ - ^)
Answer:
75 mins or 1 hour 15 min :)
Step-by-step explanation:
The answer would be 10. Im not quite sure if thats the answer, im sorry if i get it wrong. Otherwise i hope this helped you! :)
Easiest way is if you substitute each point (x,y) into each set of equations and both points work for both equations in the system of equations, then it is the correct answer
Otherwise substitute one equation for y in the other equation:
2x + 6 = x^2 + 5x + 6
-2x - 6. -2x -6
0 = x^2 + 3x. Factor
0 = x (x + 3)
Solve: x = 0. x + 3 = 0. ——> x = -3. Substitute into one original equation to get y value for
y = 2x + 6.
y = 2(0) + 6. y = 2(-3) + 6
y = 6. y = -6 + 6 —-> y = 0
(0 , 6) And. (-3 , 0)
For this you divide the total spent by the total number of pizzas...
16.50/ 3 = $5.50 per pizza.
