For this case we have that by definition the Greast Common Factor is the biggest factor that two or more numbers have in common.

So, we look for the factors of 12, 18 and 84:

12: 1,2,3,4,6,12

18: 1,2,3,6,9,18

84: 1,2,3,4,6

Thus, we can see that the GCF of 12, 18 and 84 is 6.

Genrish500 [490]

Answer:

24 km/h

Step-by-step explanation:

The speed of the boat in the lake = x
The speed of the current = 3 km/h

<u>Required equation:</u>

54 / (x + 3) + 42 / (x - 3) = 96/x
9x(x - 3) + 7x(x + 3) = 16(x + 3)(x - 3)
9x² - 27x + 7x² + 21x = 16x² - 144
6x = 144
x = 144/6
x = 24 km/h

W are r are not valid grades. I have attached the table associated with this question

Answer:
GPA = 3.625

Explanation:
GPA stands for "Grade Point Average".
It can be easily calculated by dividing the total grade points with the total number of hours.
Taking a look at the table, we can find that:
Total grade points = 29
Total hours = 8
Therefore:
GPA = 29 / 8 = 3.625

Hope this helps :)
