the first one

the third one

the fourth one

Step-by-step explanation:

1. x does equal 9

2. the equation would lead to x being canceled out so there would be an x in your answer

3. x does equal 30

4. x does equal 6

5. x should equal 135

your answer would be 10x - 1

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
