Question

Write a system of two linear equations to represent deshauns performacnce. Let x and y have the same representation as they did in kelly's system of linear equations in part A.

Answer 1

ANSWER

equation 1: x + y = 12

equation 2: 4x + 7y = 72

EXPLANATION

The variables represent:

• x: number of arrows that landed in the ring surrounding the bull's eye

,

• y: number of arrows that landed in the bull's eye

The total arrows that Deshaun has is 12, so the sum of all the arrows is 12:

$x+y=12$

Then it is said that he scored 72 points. If each arrow that lands in the ring worths 4 points and each arrow that lands in the bull's eye worths 7 points then the total points is:

$4x+7y=72$
