2
Step-by-step explanation:
(2 7/6) - 7/6= 2
2 7/6 is just 2+7/6 then subtract 7/6 and get 2.
Answer:
assuming you're asking whats g(2+3) the answer is 40
Step-by-step explanation:
8(2+3)
8(5)
8 x 5 = 40

This is a pretty easy half life problaem.
There are formulas for calculating this using "e" but I have a simpler formula which you can find here:
http://www.1728.org/halflife.htm
Ending Amt = Beginning amount / 2^n
where n is the number of half-lives
n = 1
Ending Amt = Beginning amount / 2^1
Ending Amt = 1,000 / 2
Ending Amt = 500 grams
Two digit means it'll have two numbers, and we already know that one of them is 8, and the other is half of 8. Well half of 8 is 4. So know we know the two digits (8 and 4) so that could be 84 or 48. Well we also know that the number has to be divisible by 8. 84/8=10.5 so that's not it, 48/8=6 that one works perfectly. So the answer is 48 :)
His model is incorrect because 20 x 7 is not 14, it is 140. If he had 140 instead of 14, he would have been correct.
I haven't done division like that in a long time, so this is what I think it will look like. I didn't add other work (multiplying 4 with #'s) but you can if you have to
