Answer:
Joelle:155,Anita:270
Step-by-step explanation:
Hello, I think i can help you with this.
Step 1
define
Let
A, Anita's score
J, Joelle’s score
According to the question data
their combined total score for one game was 425 points.in mathematics terms it is: A+J=425,equation (1)
Anita’s score was 40 less than twice Joelle’s: it means that you can take twice joelle's score and subtract 40 to obtain Anita's scor 2J-40=A,equation (2)
,
Step 2
find the values A and J
replace A from equation (2) into equation (1)
A+J=425
(2J-40)+J=425
solve for J
2J-40+J=425
3J=425+40
J=465/3
J=155
Now, put the value of J in equation (1) or equation (2) to find A
A+J=425
A+155=425
A=425-155
A=270
Hence, Joelle:155,Anita:270
Have a good day
It would be the last choice Joelle: 155, Anita: 270
