Step-by-step explanation:
3pizzas=7*3=21
he have 15 so
21-15=6$ will be needed
40% of 315 miles is 315 x 0.40 = 126 miles.
This means he drove 126 miles to get to the event.
He drove at 60 miles per hour, so divide the miles by the speed:

Answer:
<h2>
B. x = 9, y = 2</h2>
Step-by-step explanation:
You can just check the values:
A. x = 2, y = 8
x + 3y = 2 + 3×8 = 26 not <16 ⇒ NOT these values
B. x = 9, y = 2
x + 3y = 9 + 3×2 = 15 <16
x + y = 9 + 2 = 11 >10
YES, x = 9, y = 2 are solutions of the system of inequalities
C. x = 1, y = 5
x + 3y = 1 + 3×5 = 16 not <16 ⇒ NOT these values
D. x = 7, y = 2
x + 3y = 7 + 3×2 = 13 <16
x + y = 7 + 2 = 9 not >10 ⇒ NOT these values
