Question

Write an inequality for this sentence. Then solve the inequality. Fifteen less than a number is at most 6.

Answer 1

@iGreen. @silverr

Answer 2

fifteen less than a # is at most 6.
y - 15 < 6

think you can try from here?

Answer 3

y = 21?

Answer 4

the sign is not =
what do you think it is? did you divide? should it be flipped?

Answer 5

@OpenStudyRocks5* ?

Answer 6

@silverr Thinking. Im not very good at inequality's. :(

Answer 7

okay :)
it is only flipped when you divide by a negative. you're not dividing at all in this one, and not doing anything with a negative. therefore ?

Answer 8

I feel like an idoit :|

Answer 9

@iGreen.

Answer 10

no, your not ! you just need practice is all :)

Answer 11

the sign stays the same because you are doing nothing.

Answer 12

@iGreen.

Answer 13

The inequality is wrong..

I believe it's:

\(y - 15 \le 6\)

Our first step is to add 15 to both sides, what do you get?

Answer 14

Now when you say both sides what do you mean? 15 and 6? I haven't got that yet.

Answer 15

Yeah, we are adding 6 + 15

Answer 16

6 + 15 = 21

Answer 17

Yes, so we have:

\(y \le 21\)

Answer 18

But the answers are longer than that so it cant be that... here ill give some of the answers.... @iGreen.

Answer 19

x + 15 ≤ 6; x ≤ 21. Which is probally right cause of what you just said (y ≤ 21)

Answer 20

Yep, you got it..but the first equation is wrong..it's not:

\(x + 15 \le 6\)

It's:

\(x - 15 \le 6\)

Answer 21

so x - 15 ≤ 6; x ≤ 21

Answer 22

Yep, you got it.
