Answer:

3 miles

Step-by-step explanation:

to find the amount of miles it is to the library you have to find how many miles it is when the minutes are zero

so when x = 0 what is y

0 + 7y = 21

7y = 21

y is 3

so that means the library is 3 miles away from his house

There were 254 tickets purchased for a major league baseball game. The lower box tickets cost ​$12.50 and the upper box tickets
Nesterboy [21]
L = Lower box tickets amount.

U = Upper box tickets amount.

we know the whole amount sold were 254 of both, thus L + U = 254.

since we know the price of L is 12.5 for each, then the amount of money sold total for all of them has to be 12.5 * L, or 12.5L.

and the U is 10, so its total amount of money for it is 10U.

we also know that the total amount for both spent was 2745, thus 12.5L + 10U = 2745.

\bf \begin{cases}
L+U=254\implies \boxed{L}=254-U\\
12.5L+10U=2745\\
---------------\\
12.5\left( \boxed{254-U} \right)+10U=2745
\end{cases}
\\\\\\
3175-12.5U+10U=2745\implies 3175-2.5U=2745
\\\\\\
3175-2745=2.5U\implies 430=2.5U\implies \cfrac{430}{2.5}=U\implies 172=U

so, 172 Upper box tickets were sold then.

how many Lower box tickets were sold?  well, L = 254 - U

A bag holds 6 green, 9 red and 4 blue marbles a marble is selected at random what is the probability of not selecting a red marb
Butoxors [25]

Answer:

The probability of not selecting a red marble, P(R)'  = 10/19

Step-by-step explanation:

The probability of an event occurring is equal to the number of ways the required event occurs divided by the number of possible outcomes

The number of ways of an event not occurring is 1 less the probability of the event occurring

The number of green marbles in the bag = 6

The number of red marbles in the bag = 9

The number of blue marbles in the bag = 4

The sum of the marbles in the bag, n = 6 + 9 + 4 = 19

The number of ways of selecting a red marble = 9 ways

The probability of selecting a red marble = 9 ways/19 marbles = 9/19

The probability of not selecting a red marble = 1 - 9/19 = 10/19 = 0.\overline{526315789473684210}

The probability of not selecting a red marble P(R)' = 10/19
