Answer: Explained in the step-by-step
Step-by-step explanation:
We want to isolate x, and remember, what we do to one side we do to the other:
(x+3) * 3 2/5 = 15 3/10
(x+3) * 3 2/5 divided by 3 2/5 = 15 3/10 divided by 3 2/5
x + 3 = 153/10 * 5/17
x + 3 = 765/170
x + 3 = 153/34
x + 3 = 4.5
x + 3 - 3 = 4.5 - 3
x = 1.5
Check:
(1.5+3) * 3 2/5 = 15 3/10
4.5 * 3 2/5 = 15 3/10
(3 2/5 = 3.4 and 15 3/10 = 15.3)
4.5 * 3.4 = 15.3
15.3 = 15.3
The distributive property says that the following is true:
In our problem, we will consider the term outside (or 
in the first equation) to be 
and we will consider the expression inside the parentheses to be 
. To use the distributive property, we are going to apply the outside term to all terms within the second expression. This is represented as:
We can now use the distributive property again to simplify the new expression:
The answer is x³ + x² - 2x + 12.
First, you add up the non-$10 winning cars so 100+25=125.
then you take 5:125 because you want the winning 10$ against not winning. the to get 1 you divide both numbert by 5 to get 1 on the left. so you get 1:25.
hope i helped:)

Answer:
4n - 2
Step-by-step explanation:
Greater = 2n
Smaller = 2n - 2
Sum = 2n + (2n - 2)
Sum = 2n + 2n - 2
Sum = 4n - 2
