Answer:

Step-by-step explanation:

Solving simultaneously

14v + 12b = 612 .....(1)

7v + 13b = 516 ......(2)

eqn (1) - [eqn (2) x 2]

14v + 12b = 612 ...(1)

14v + 26b = 1,032 ...(3)

-14b = -420

b = 30

7v + 13(30) = 516

7v + 390 = 516

7v = 126

v = 18

therefore 1 bus carries 30 students and 1 van carries 18 students

The number of miles she cycles per day since 7 days make a week is;

  • 105/7 = 15.

Hence, it follows that the equation; (15+r) = 20 represents the daily distance covered by cycling and running.

On this note, it follows that;

  • r = 20 -15 = 5.

Hence, The solution is 5, which represents the number of miles she runs each day.

Use set notation to write the members of the following set, or state that the set has no members. Odd numbers between 2 and 82 t
adell [148]

Let the set of all Odd multiples of 9 between 2 and 82 be denoted by D, then, using set-builder notation,

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}

The odd multiples of 9, m, in the range 2\le m \le 82 form the set

\{9,27,45,63,81\}

Each member of the set is a term of the arithmetic progression

U_n=18n+9

where the values of n range from 0 to 4, or 0\le n\le 4

Putting these facts together, we get the result

D=\{ 18n+9 \mid n \in \mathbb{N}, 0\le n\le 4 \}
