60, 75, 90, 105, 120
Step-by-step explanation:
No she did the Division wrong because she got 5 1/2 for her multiplication it so she should recheck and try the multiplication over to get the answer right
The total of her first six quizzes is 75*6 = 450
Let her seventh score be x
The total of her seven quizzes be 450+x
Then, (450+x)/7 = 77
x = (77*7) - 450 = 89
Her seventh score is 89
x =
Answer:
x=-11
Step-by-step explanation:
the (x+14) line is half of the (17+x) line, so in order to solve this we would have to set it up like this:
2(x+14)=17+x
distribute
2x+28=17+x
x=-11
