Answer:

The right answer is: Option C: x+5

Step-by-step explanation:

Let m1 be the miles Lukas drove on Saturday and Let m2 be the miles he drove on Sunday

$m_1 = 4x-5\\m_2 = 3x-10$

The difference can be found out by subtracting m2 from m1

minus sign will be distributed into the bracket and alike terms will be added or subtracted according to sign.

$m_1 - m_2 = 4x-5 - (3x-10)\\= 4x-5-3x+10\\= x+5$

The difference of miles driven is: x+5

Hence,

The right answer is: Option C: x+5

Answer:

a(n) = -3(-1/5)^(n - 1)

Step-by-step explanation:

From the first term, -3, we get the second term, 3/5, by multiplying -3 by -1/5.

Thus, the common ratio is -1/5.

The general formula in this case is a(n)=(first term)(common ratio)^(n - 1), or

a(n) = -3(-1/5)^(n - 1)

A discount string 5/2/1 means the following:
1) Apply 5% discount to the original price.
2) Apply 2% discount to the result of step 1).
3) Apply 1% discount to the result of step 2).
We have then that the result will be given by:
625 * (0.95) * (0.98) * (0.99) = 576.05625 $
Then, the price of each skateboard is:
(576.05625) /20=28.8028125 $
