First, multiply. 7x-14-4x+9. Now, add the like terms. 3x-5.
Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.

On the left, the 2y cancel. Simplify the right:

And we're done!
We have 26 letters and 10 digits.
So, we have 26 choices for the first letter, 25 choices for the second letter (we can't pick the one we already chose), and 10 choices per digit (we can always choose any digit, because we can repeat them).
This leads to a total of

possible car targs.
The three remaining slices would form 108 degrees.
Hope this helped (and that I was right) =P
Let p = number of pennies we need to find.
(3/10)/(4/5) = p/440
Solve for p to find your answer.
