that has been investigated is wether injuries of football players tend to be more serious on artificial turf instead of grass. A study followed 24 NCAA division 1A college teams over 3 seasons.
In total, there were 1,050 injuries that occurred on field turf. Of the field turf injuries, 83.3333% were minor, and 10.857% were substantial. 77.972% of grass injuries were minor. 4.26% of injuries occurred on grass and were severe. How many injuries were severe and occurred on field turf? How many injuries were severe?

Answer:
Option (A)
Step-by-step explanation:
Te given equation is,
-qx + p = r
Toe find the value of x,
By subtracting p from both the sides of the equation.
-qx + p - q = r - q
-qx = r - q
By dividing the whole equation by (-q),
x =
x =
Therefore, Option (A) will be the answer.

Answer:
A. (4, 12)
Step-by-step explanation:
Adding the second equation to twice the first will eliminate y.
2(10x +2y) +(3x -4y) = 2(64) +(-36)
23x = 92 . . . . . . . . simplify
x = 4 . . . . . . . . . divide by 23
This value matches choice A: (4, 12).
