5 : 30
5x= 125
x= 25
so
5*25 : 30*25
125 : 750
750 minutes.
12 hours 30 minutes.

You multiply the original price by .20
In equations we always want to do the same thing to both sides so the equation stays equal
in an equation with one unknown (x) we try to get the unknown on one side
so -(x-10)
this means that you multiply everything in the equation by -1 or in other words you make everything in the parenthasees the opposite sign of what it is so
6x+3x-x+10=20x
add like terms
8x+10=20x
subtract 8x from boths sides
10=12x
divide both sides by 12
10/12=x=5/6
Answer:

Step-by-step explanation:
If a parabola has its vertex on the y-axis, then its equation is

This parabola passes through the point R(3,9), then

The area of the right triangle PQR is

Find PQ and QR, if 

Now,

We get two possible points
and 
For point 

So,

For point 

So,
