The probability is 1/6, 16%, or 0.16
Answer: x = 23 and y = 13
Explanation:
let x and y be the two number.
Where:
(x + y)/2 = 18 => x + y = 18 x 2 = 36
and:
x - y = 10
Thus we get:
x + y = 36 (1)
x - y = 10 (2)
Add (1) and (2):
x + y + x - y = 36 + 10
2x = 46
x = 23
If x = 23
then x - y = 10
23 - y = 10
-y = -13
y = 13
To simplify the ratio. You have to find both of these numbers Greatest common factor. Which happens to be 3 :P
So divide each number by 3
15 ÷ 3 = 5
---------------
3 ÷ 3 = 1
So this means our new simplified ratio is...
5 seconds to 1 minute.
Good Luck! :)
Answer:
Step-by-step explanation:
x = number of windows being washed
3x + 15 > = 50 (thats greater then or equal to)
3x > = 50 - 15
3x > = 35
x > = 35/3
x > = 11 2/3
so he would have to wash 12 windows to get the minimum amount.....any more window money would go to the additional accessories.
