Answer:Question
Please help?
(I learned this way back so I kind forgot)
1 Which model represents 2(-3)
figure c represents 2(-3)
Answer. 25 , 26 and 27 are the three consecutive integers.
this sum must be even, so 3 consecutive even integers would be n, n+2 & n+4 whose sum is 3n + 6.
Set that to either 78 or 7878, whichever is intended, & solve for n. If 78 is their grand total, then those 3 consecutive even numbers have to be 24, 26 & 28.
I believe it would just be y-15 because if there aren't anymore numbers then that is all you can do
7. 0.4
8. 0.55
9. 0.125
10. 3.5
11. 11.8
12. 7.625
13. 0.556 rounded nearest 10th = 0.6
14. 0.455 rounded nearest 10th = 0.5
15. 6.714 rounded nearest 10th = 6.7
Hope this helps :)
