Question

I WILL MEDAL!!!!!!!!!!!!!
Anita and joelle bowl together and there combined total score for one game was 425 points. Anita's score was 40 less than twice joelle's. what were there scores?
A. joelle: 155 , Anita: 270
B. joelle: 180 , Anita: 245
C. joelle: 270 , Anita: 155
D. joelle: 140 , Anita: 240

Answer 1

x + y = 425 --> x = 425 - y
now sub 425 - y in for x
y = 2x - 40
y = 2(425 - y) - 40 -- distribute through the parenthesis
y = 850 - 2y - 40
2y + y = 850 - 40
3y = 810
y = 810/3
y = 270
now sub 270 in for y in either of the equations to find x
x + y = 425
x + 270 = 425
x = 425 - 270
x = 155

anita's score (y) = 270
joelle's score (x) = 155

Answer 2

does this help a little

Answer 3

its c

Answer 4

correct?

Answer 5

x + y = 425 --> x = 425 - y
now sub 425 - y in for x
y = 2x - 40
y = 2(425 - y) - 40 -- distribute through the parenthesis
y = 850 - 2y - 40
2y + y = 850 - 40
3y = 810
y = 810/3
y = 270
now sub 270 in for y in either of the equations to find x
x + y = 425
x + 270 = 425
x = 425 - 270
x = 155

anita's score (y) = 270
joelle's score (x) = 155
