Explain what exactly ? are we solving for a variable ?
7.1 is the value of Ef where cd=df
Answer:
6 miles
Step-by-step explanation:
You Can make a proportion
=
Now cross multiply
45*26/3 is 360
and 60*x is 60x
make an equation
60x=360
x=6
So 6 miles
Answer:

Step-by-step explanation:
We will use the point slope formula: 
We will start by finding the slope(
).
The formula for slope is

So if we just choose 2 random points on the line:
I choose (0,2) and (4,1), we get:

That's our slope.
Next we need to find the y-intercept(
). We can find that by looking at the graph. It is where x=0. So in this case y=2 when x=0.
So in point-slope form the equation is:

L=1.5w
P=l+w
40=2.5 w
W=16
L=1.5(16) =24
Length is 24
Width is 16
