A. The hexagon as the series is adding a side each time. So you started with 3, 4, 5...
You would do 2^2 and will come out to 4. Your mixed number is 4. Then you will do 3/4^2 and will come out to 9/12 Your answer is 4 9/12
The fraction he added is 6/30, or 1/5.
I'm not 100% sure about the equation you want me to use but I did the work this way:
5/6+x/30=31/30 (the denominator has to equal 30 because you are adding. You need a common denominator which is why you need to change 5/6. We can label the numerator as a hidden value x)
25/30+x=31/30
You can then work backwards and basically subtract 25 from 31 and get 6; so x=6
A. 515
b. 43
c. 3510
d. 1.9705
Answer:
12.5
Step-by-step explanation:
First, we look at the multiplication. 0.5*5 would equal 2.5. Then we would subtract that from 15. 12.5!
