Answer:
x= 2, y= 1
Step-by-step explanation:
x= 2y
2x +5y =9
substitute x
2 *2y +5y = 9
4y +5y = 9
9y = 9
y =1
x= 2*y = 2*1= 2
Answer:
Let the number be x
Given:
11 + 5x = 20 + 2x
5x - 2x = 20 - 11
3x = 9
x = 3
The number is 3.

Answer:
The question continues ; I take it is defined as a set of five white and one red number how many possible different Powerball tickets can be purchased how many possible different winning Powerball tickets are there
Step-by-step explanation:
he concept of combinatorics ( combination and permutation) is applied her
nPr = n!/(n-r)!
nCr = n!/(n-r)!r!
Hence number of possible different powerball tickets = number of ways of selection
= selecting 5 white ball from a total of 69 and selecting a red ball from a total of 26
= 69C5 x 26C1
using the formula above for combination
= 69!/(69-5)!5! x 26!/(26-1)!1!
= 292, 201, 338 ways
I believe its 765 meters.
75x15 (LxW)=255 meters
255x3=765 meters
