Question

The sum of two consecutive integers is at least 36. What is the least possible pair of integers?
A. 17 and 18
B. 19 and 20
C. 18 and 19
D. 16 and 17

Answer 1

"Sum" means 'add'. 'Consecutive' means they are in order without skipping one.
2,3 are consecutive numbers. 2,4 are not consecutive.
Add each set of two numbers to see which ones are 36 or higher.
Of all the ones that do add to 36 or more, they want the smallest pair of numbers as the answer.

Answer 2

so then would it be c?

Answer 3

A. 17 + 18 = 35
B. 19 + 20 = 39
C. 18 + 19 = 37
D. 16 + 17 = 33
Only two sets are equal to 36 or more.
Yes C is the answer.

Answer 4

Yes. C. is correct.

Answer 8

i have another question

Answer 9

\[5\le \frac{ x }{ -2 }\]

Answer 10

\[-7\ge13-5x\]
this is my next one too. so I need help with both.

Answer 11

both of the last two questions i put i need help with

Answer 12

nvm i got them. you took too long. jk! ;P

Answer 13

Sorry. For 5 <= x/(-2)
Did you remember to switch the direction of the inequality sign after you multiplied both sides by (-2)?

Answer 14

Answer would be x is less than or equal to -10.

Answer 15

For the next one: -7>=13-5x
Add 5x to both sides to get: -7-5x>=13
Then add 7 to both sides to get: -5x>=13+7
So -5x>=20
Next you divide both sides by -5 BUT you have to remember to switch the direction of the inequality sign!
So x<=-4

Answer 16

ok thank you! I got it before you typed the answer! xD you took to long! lol! jk
