Solve for x.

2/3x=10

Question

Solve for x.

2/3x=10

iluvsoccer · Answer

2/3x basically means 2/3 * x 
so now in order to get x on one side, we have to do the opposite.
2/3 / 10/1

iluvsoccer · Answer

2/3 * 1/10

rose4825 · Answer

$$\frac{ 2 }{ 3 }x=10$$
Get x on it's own by multiplying both sides by 3/2.
$$\left( \frac{ 3 }{ 2 } \right)\frac{ 2 }{ 3 } x=\left( \frac{ 3 }{ 2 } \right)*10$$
Multiply 3/2 and 10. To make this easier, make 10 a fraction by writing 10/1
$$x=\frac{ 3 }{ 2 }*\frac{ 10 }{ 1 }$$
Multiply.
$$x = \frac{ 30 }{ 2 }$$
Simplify.
$$x=15$$

Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the other train travels at 80 mph.

How much times passes until the trains are 600 mi apart?

rose4825 · Answer

So basically the word problem contains the following equation:
$$70x*80x=600$$
Add.
$$150x=600$$
Get x on its own by dividing both sides by 150.
$$(150)\div150x=\frac{ 600 }{ 150 }$$
Simplify.
$$x=4$$

I don't know what the unit of time that the question is asking, but I would say hours based on the fact that the trains are traveling "mph" so that answer (in my opinion) would be 4 hours.
