4 / 1 = 1 / x....4 miles to 1 hr = 1 miles = x hrs
cross multiply
4x = 1
x = 1/4.....it would take 1/4 of an hr (or 15 minutes) to walk 1 mile

its c

Answer:

Step-by-step explanation:
There are 6 sides on dice, therefore the sample space would be 6 (<em>the</em><em> </em><em>sample</em><em> </em><em>space</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>denominator</em>). We were asked to find the probability of getting a 1 or a 6. Since we were given 2 options 1 or 6, it therefore means that we are trying to find the probability of the dice rolling on 2 out of the 6 sides it has. Therefore the probability would be:

A third as a decimal is

Step-by-step explanation:
4x2 - 25b2
We can solve it by the squares so
(2x - 5b) (2x + 5b)
2) x2 - 81
The same case is here so
(x - 9) (x + 9)
If put in order:
12,14,15,15,16,18,20,20,21,22
it should be 17.
