So to run 10km, you need to run 6.25 times the trail. (Or 7 if you only accept whole numbers as answers, we need to round up).
<h3>How many times will you need to run this trail in order to run 10 kilometers?</h3>
If you run the trail x times, then you will run:
y = x*1mi
Now remember that:
1 mi = 1.6 km
Replacing that, we get the linear equation:
y = x*1.6km
Now we want to find the value of x such that:
x*1.6km = 10km
Dividing both sides by 1.6km
x = 10km/1.6km = 6.25
So to run 10km, you need to run 6.25 times the trail. (Or 7 if you only accept whole numbers as answers, we need to round up).

Answer: y = 5/2 or 2.5
Steps:
6(2y - 1) - 2(2y) = 14
12y - 6 - 4y = 14
8y - 6 = 14
8y = 20
y = 20/8
y = 5/2 or 2.5
Answer:
-11.5
Step-by-step explanation:
I just did it on the calculator :)
Answer:
This system has infinite solutions and it would be much easier to solve it by elimination but substitution it is.
Step-by-step explanation:
-3x+3y=9
-x+y=3
Isolate either x or y in any of the equations. I'll go with the second.
y = 3+x
Now substitute this for y in the first equation.
-3x+3(3+x)=9
Distribute the 3
-3x+9+3x=9
Combine like terms:
9=9
0=0
It's infinite
