For each of the following questions, choose the correct answer. Anita and Joelle bowl together and their combined total score for one game was 425 points. Anita’s score was 40 less than twice Joelle’s. What were their scores? Write a system of equations to model the problem if x represents Joelle’s score and y represents Anita’s score. A. x + y = 425 y = 2x + 40 B. x + y = 425 y = 2x – 40 C. x + y = 40 y = 2x – 425 D. x – y = 425 y = 2x – 40 @Directrix
brb @Directrix look at the question while i am away please
The first step is the assignment of variables.
x represents Joelle’s score y represents Anita’s score
x + y = ?
x=y=425
sorry if i don't reply back fast I am eating while working
Is that how this happened? --> x=y=425 x + y + ?
sorry messed up x+y=425
To avoid confusion, first code the equations with the letters of the participants' names; Anita’s score was 40 less than twice Joelle’s.
Anita’s score was 40 less than twice Joelle’s. A = 2*J - 40
B is my guess
We are not doing answers yet. We are doing equations.
ok ok sorry
A = 2*J - 40 -------------- Is Anita x or y? ---?
y
Yes, so the equation goes to y = 2x - 40 Great news: It is time to pick the correct option.
B
Yes, that is what I think.
Close and post.
