Two students push on a car stuck in the mud with a force of 20 Newtons,
but they are unable to move it. How much work have they done?
A) 40 Joules
B)Not enough information given to answer this question.
C)20 Joules
D)0 Joules

B.

Step-by-step explanation:

You cannot determine how much more they need to push if you dont have the number of newtons's the car weighs

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
