Super Bowl Math Question!?!?
Last week your favorite football team ran a total of 108 offensive plays. There were twice as many running plays as passing plays. Write a system of equations to represent this information given that "x" is the number of running plays as passing plays. football and math fans.. I dare you to answer this. ( Im not asking for the "answer" which is 36 and 72 im asking for the equation that gives you the answer, and you must use "y" and "x")
.

Answer 1

2x+y=108.



x=running plays

y=passing plays

Answer 2

B= Buccaneers R= Raiders Rush B= R+ninety B+R= 560 Problem: B+R=560 (R+ninety)+ R= 560 (installed new equation for B) 2R +ninety= 560 2R= 470 R= 235 So the Raiders Rushed for 235 yards.

Answer 3

x + y = 36 and 72 - but I'm guessing

Answer 4

no way..i'll get a headache before the game if i do that.
