I put C cause idk
OpenStudy (maddy1251):
A.19 and 20
B.17 and 18
C.18 and 19
D.16 and 17
We will add these.
OpenStudy (markchernioglo):
So try all your pairs:
16+17 = 33
17+18 = 35
18+19 = 37
19+20 = 39
So The first two ones don't add up to 36, so they are out.
Next you are left with 18+19=37 and 19+20=39 So 37<39
That means 18+19 < 19+20
So the smallest pair of integers that add up to at least 36 is 18+19.

Not greater, but clsoer to 36 as we could get.
OpenStudy (markchernioglo):
no what added to 36
OpenStudy (markchernioglo):
yup maddy is correct
OpenStudy (maddy1251):
None added to 36, but we did have 37, which is close enough, because the rest where greater than 36.
OpenStudy (markchernioglo):
lol good job everyone

In math, we don't always get handed easy situations, like this, so we gotta find what works BEST. Not a problem. :)
