The sum of the quotients of 25x/5x and the quotient of 8x^2/x

Hey there!

In order to find the quotients of these two expressions, you first divide the numbers as you would with numbers without any unknown terms, then you divide the unknown terms. In order to divide exponents, you just need to subtract the exponent numbers from left to right. Remember that x is the same as x¹. 

25x / 5x = 5x⁰ = 5
8x² / x = 8x¹ = 8x

Finally, just put these together into an addition expression to get (8x + 5). Hope this helped you out! :-)

480 pennies dated after 2000.

Step-by-step explanation:

1. Pennies dated before 1980 (x) - 25%,

All pennies (1,200) - 100%.

Then

2. Pennies dated from 1980 to 2000 (y) - 35%,

All pennies (1,200) - 100%.

Then

3. Rest pennies are dated after 2000, then
