Answer:
10 more packs
Step-by-step explanation:
400 sweets bought 25 such packs = 400*25=10000
2000 each one gets 7 = 2000*7=14000
14000-10000=4000
4000/400 is 10.
So 10 more packs.

We use negatives to show it is below sea level

means to say that for any given
, we can find
such that anytime
(i.e. the whenever
is "close enough" to 5), we can guarantee that
(i.e. the value of
is "close enough" to the limit value).
What we want to end up with is

Dividing both sides by 3 gives

which suggests
is a sufficient threshold.
The proof itself is essentially the reverse of this analysis: Let
be given. Then if

and so the limit is 7. QED
Answer: 72 units^2
Explanation:
Triangle to the left, you do 5(6) and get 30, but since it's a triangle, you divide by 2 and get 15. Middle rectangle, 6(8) is 48. Right triangle, 3(6) is 18, 18/2 is 9. Add them all up 15+48+9 and you get 72. Hope this helped!
