r/4 – 10 > – 11
- 8w+7>5
2< 6/5c+14
0.6 > 1.4+2.4x
5< 3- 2x/3
1/6 - 8 <8r - r/6
-6x + 3< -18
y/2+1< -3/2
9-g<4
-12 > -4x + 8
-2/5x-10>2
-6 > -2x + -10
i no its a lot but it was lk i worksheet with 60 questions!
im n 6th grade n if it is help me
with inequalities you do the same as if it was an equal sign. The ONLY difference (and this is important) is that if you multiply or divide by a NEGATIVE you have to switch the sign from < to > or vice versa.
For example on your second one:
- 8w+7>5
subtract seven from both sides = -8w > -2
then divide both sides by -8
w < 1/4
because we divided by -8 the sign switches around.
But like for your first problem, r/4 - 10 > – 11 you just add 10 to both sides, and multiply by 4. you dont need to switch signs. so you would get r > -4
