Answer:
B
Step-by-step explanation:
Let the number = x
2/5 (x - 1)
<
3/5 (x + 1)
2/5 (x - 1 ) < 3/5(x+ 1) Multiply both sides by 5
2(x - 1) < 3 ( x + 1) Remove the brackets.
2x - 2 < 3x + 3 Add 2 to both sides
2x < 3x + 5 Subtract 3x from both sides
2x - 3x < 5
- x < 5 Here's the tricky part . Divide by - 1
x > -5 Notice what happened. The < become > That happens because you have divided (or multiplied) by a negative number.
The original question 2/5 (x - 1 ) < 3/5(x+ 1) was graphed. The red part is every value that satisfies the inequality. You should be using a y and x together to find a more suitable answer using this program. But if you just look along the x axis, you will see that the < has been turned around.
B The second one from the top.
