Answer:

x=-32

Step-by-step explanation:

So we have the equation:

x-2(x+10)=12

Distribute the -2:

x-2x-20=12

Combine like terms:

-x-20=12

Add 20 to both sides:

-x=32

Divide both sides by -1:

x=-32

And we're done!

If rahul rows 16 km upstream and 24 km down steam taking 4 hours each, then the speed of the stream.
gladu [14]

The upstream speed is 4 km/hour and the down stream speed is 6 km/hour

<h3>Calculating Speed </h3>

From the question, we are to calculate the speed of each stream

From the given information,

"<em>Rahul rows 16 km upstream and 24 km down stream taking 4 hours each</em>"

For the Upstream,

Distance = 16 km

Time = 4 hours

Using the formula,

Speed = Distance/ Time

Speed = 16 km / 4 hours

Speed = 4 km/hour

For the Down stream,

Distance = 24 km

Time = 4 hours

Thus,

Speed = 24 km / 4 hours

Speed = 6 km/hour

Hence, the upstream speed is 4 km/hour and the down stream speed is 6 km/hour
