Step-by-step explanation:
x = number
3x - 15 = (x - 12)×-4 or (12-x)×-4
3x - 15 = -4x + 48 or -48 + 4x
7x = 63, x = 9 or
33 = x
If he hikes 6 miles in 2 hours, his speed is...
6/2 miles/hr
6/2 reduces to 3/1 so he is traveling 3 miles/hr.
To find how far he goes in 9 hours, multiply speed × time...
9 hours × 3 miles/hour =
27 miles
Answer:
1/15
Step-by-step explanation:
There are a total of 10 fruits, 3 of which are apples.
The probability that the first selection is an apple is 3/10.
There are now 9 fruits remaining, 2 of which are apples. So the probability that the second fruit is an apple is 2/9.
The total probability is (3/10) (2/9) = 1/15.
