6x - 17 = 7 ........ added 1x to both sides
6x = 24 ............. added 17 to both sides
x = 4 ................. divided by 6 on both sides
so x=4
x = 6
given f(x) = 310, we obtain the equation
10 + 50x = 310 ( subtract 10 from both sides )
50x = 300 ( divide both sides by 50 )
x = = 6
We know that 10% of 60 is 6.
60*.1= 6
So,
6+6= 12 or 20% of 60.
12 is the number.
I hope this helps!

Answer:
2½ h
Step-by-step explanation:
Assume the graph is like the one below.
The graph shows how Erin's distance varies with time.
To find out how long it takes Erin to cover 25 mi, find 25 mi on the vertical axis.
From there, draw a horizontal line until it hits the graph.
Then drop a vertical line to the horizontal axis.
It hits half-way between 2 and 3.
It takes Erin 2½ h to run 25 mi.
