Question

The ones with red are the ones I have not done and the ones that I need help with! Due tomorrow plz help!

Answer 1

5 is 60, 4 plus 7= 11. 11+ 7=18. 18+7= 25 annnddd all the way to the nineth which is 53 +7 = 60

Answer 2

3 is wrong. It is 105,000
4) 13/60=0.21666 0.21666*360=78 so 78 degrees
5)sequential difference is 7 and the first term is 4 so 7n-3
6)4x-4=2x-10,2x=-6,x=-3
7)5(4)(5)+4^2=100+16=116
8)(-3,7)
11)a=180-70=110 b=a=110 c=70
12)Sum or angles of a hexagon=(6-2)(180)=720. 720/6=120
13)3/51 because there are only 3 aces in the deck and 51 cards in total
You did 14 wrong. It should be 9/12*144=108
17)First and third. Plug in 0 for x
18)72/9*2=16 72/9*7=56 so 16:56
19)2*3+2*3/2=9
