Answer 1

How many of those pairs add up to at least 36? If more than one does, which one is the smallest?

Answer 2

i say B

Answer 3

Try them all out if you have doubts.

Answer 4

Does 17 + 18 = at least 36?

Answer 5

@Luis_Rivera, they have to be integers.

Answer 6

@Luis_Rivera check your arithmetic

Answer 7

im confused

Answer 8

@pinkpearl12000 you have 4 pairs of numbers. you're looking for the smallest pair that adds up to at least 36. Add up each pair, pick the smallest one that adds up to at least 36. what is confusing?

Answer 9

@Luis_Rivera Dude, you aren't reading the problem statement correctly.

Answer 10

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.

Answer 11

Ohhhh,but that adds up to 37

Answer 12

37 is at least 36, isn't it?

Answer 13

No, you didn't execute any of your methods correctly.

Answer 14

And only the first one would give you the right answer.

Answer 15
