Call Anita's score "y" and Joelle's score "x".

1) "<span>their combined total score for one game was 425 points"
</span>Therefore x+y=425

2)"Anita’s score was 40 less than twice Joelle’s." 
Therefore y=2x-40

Substitute:
x+2x-40=425

Solve:
3x=465
x=155

Backsubstitute:
y=2x-40
y=2(155)-40
y=270

tresset_1 [31]

Answer:

Step-by-step explanation:

) Nth term = F + (N - 1) x D, where F=First term, N=Number of terms, D=Common difference

6th row = 23 + (6 - 1) x -3

            = 23 + (5) x -3

            = 23 + (-15)

            = 8 - number of boxes in the top row.

 

b) Sum = N/2[2F + (N - 1) x D]

            = 6/2[2*23 + (6 - 1) x -3]

             = 3  [46  +    (5) x -3 ]

             = 3  [46  +      -15 ]

             = 3  [ 31 ]

             = 93 - total number of boxes in the entire display.
