Answer:

(3,3)

Step-by-step explanation:

x + y - 6= 0

x- y = 0

Add the two equations together

x + y - 6= 0

x- y = 0

-------------------

2x - 6 = 0

Add 6 to each side

2x-6+6 = 0

2x = 6

Divide by 2

2x/2 = 6/2

x = 3

Now find y

x-y = 0

3 - y = 0

y = 3

Given m||n, find the value of x and y

katrin2010 [14]

Answer:

x = 145, y = 35

<em>Brainliest, please!</em>

Step-by-step explanation:

y = 35 degrees because it and the original 35 degree angle are alternate interior angles. Alternate interior angles are congruent, or the same.

x is supplementary to y. x + y = 180. x + 35 = 180. x = 180 - 35. x = 145

Alex is in a hurry to get to work and is rushing to catch the bus. She knows that the bus arrives every six minutes during rush

Korvikt [17]

Answer:

0.6667 or 66.67%

Step-by-step explanation:

Since the waiting time is normally distributed between 0 and 6 minutes, for any time 'x' within the interval, the probability the waiting time is longer than 'x' is given by:

$P(t>x) = 1-\frac{x-0}{6-0}=\frac{6-x}{6}$

For x = 2 minutes:

$P(t>2)=\frac{6-2}{6}\\P(t>2)= 0.6667\ or\ 66.67\%$

The probability that she will have to wait more than two minutes 0.6667 or 66.67%
