I would say the answer is 7, since 21 divided by 3 is 7 and there are 1/3 as many of them
(2-7i)(9+5i)
18+10i-81i-35i^2
The answer is 35i^2 - 71i +18
5/10=1/2
4/12=1/3
3/9=1/3
6/9=2/3
2/16=1/8
10/40=1/4
2/4=1/2
6/18=1/3
4/20=1/5
9/27=1/3
7/27---- something wrong with this
8/36=2/9
Answer:2.24
Step-by-step explanation:
Answer:
M = 6
N= 7
Step-by-step explanation:
M + 7 = 3
M= 6
6 + 7 = 13, so we get 3 and carry 1
Now 1 + 4 + N = 12
1 + 4 + 7 = 12
So N = 7
Therefore,
46 + 77 = 123
