Question

I have a work sheet from my algebra 2 class involving greater than and less than signs and im confused can anyone help?

Answer 1

\[-12\le d +7\]

Answer 2

You need to isolate the variable. So, subtract 7 from both sides.

Answer 3

What do you get

Answer 4

i forgot the steps and the special tricks that are specificaly used when it involves a greater than or less than signs @twistnflip

Answer 5

The only thing you really have to remember is that when multiplying or dividing by a negative number, the sign flips.

JK nevermind, I need to check my work. You are correct, sorry about that

Answer 19

If you divide by a negative, you flip the sign.

You had the correct answer, the sign just needed to be flipped.

Answer 24

yes

Answer 28

\[\frac{-2 }{ 3 }r \le \frac{ 7 }{ 12 }\]

Answer 29

what did you get?

Answer 30

\[r \le \frac{ 21 }{ 24 }\]

Answer 31

eek ok, I actually check my work on this one and that is wrong, mind typing your steps?

Answer 32

i times both sides by the recipricole 3/-2 on both sides then i just multiplied 7/12 by 3/-2

Answer 33

ok well silly, you forgot to simplify lol. what do 21 and 24 have in common

Answer 34

3?

Answer 35

it simplifies to -7/8 (you accidentally cancelled the negative)
final answer would be \[r \ge \frac{ -7 }{ 8 }\]
