First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:
Using this, we can multiply the 7 out to the 
and 3. This gives us:
Now, let's solve for :
We can see that there is one solution for this equation because is equal to one definite value after solving. Thus, our answer is A, one solution.
You divide the number of kilometers by 0.621371 to get the number of miles per hour. I hope this helped!
Answer:
6
Step-by-step explanation:
m = 3
n = 1
Equation
m(m - n) Substitute the givens
Solution
3(3 -1 ) Evaluate what is inside the brackets.
3(2) multiply
6
No, they are not equivalent.
5(2x - y) = 10x - 5y and it is not equal to 15x - 5y.
(using distribution property)
You solve for y
4y=-6x+2
y=-6/4x+2
y=-2/3x+2
Slope is -2/3, the number in front of x is the slope.
