The first step for solving this is to cancel equal terms on both sides of the inequality.
- \frac{x}{2} < 0
Now multiply both sides of the inequality by -2 and flip the inequality sign.
-2 × (- \frac{x}{2}) > -2 × 0
Remember that multiplying two negatives together always equals a positive,, so the expression changes to the following:
2 × \frac{x}{2} > -2 × 0
Reduce the numbers with 2.
x > -2 × 0
Any expression multiplied by 0 equals 0,, so the correct answer to your question will be:
x > 0
Let me know if you have any further questions.

The speed of boat in still water is 15km/hr if needs 4 more his to travel 63 km against the current of a river than it needs to
hram777 [196]

Answer:

\frac{63}{15  - c} - \frac{63}{15  + c} = 4

Step-by-step explanation:

The systems of equations are

Let us assume the rate of the current be c

Now actual speed against the current is (15 - c)

And, the actual speed with the current is (15 + c)

Here we applied the time formula i.e. distance by speed

Also the upstream time  - downstream time = 4

Now the equations are

\frac{63}{15  - c} - \frac{63}{15  + c} = 4
