Answer:
520 miles
Step-by-step explanation:
since 4 is half of 8, you just multiply 260 by 2.
Answer:
see graph of y=3/4 x-4
Step-by-step explanation:
Assuming you mean

Below is a graph of that one. The slope is 3/4 and the interception with the y axis is at y=-4. The equation is in its normal form y=ax+b with a=3/4 (slope) and b=-4 (y intercept), so no conversion needed.
You have to be careful on how you write these equations down. It might very well be that you meant:
or 
However, those are more complex so I'm hoping for the first one... ;-)
By replacing you get:
5*7-2*11+3*(-1) = 35-22-3= 10
so the answer is 10.

Answer:
25
Step-by-step explanation:
So the denominator can be simplified to 5⁴ →
and then the 3's cancel out and we are left with 5⁴
Now our new fraction is
which then simplifies to 25
Step-by-step explanation:
40 = 2 * 2 * 2 * 5
28 = 2* 2 * 7
So now
The GCF = 2 * 2 = 4
