X=18/0.6
x=30
Answer:
56
Step-by-step explanation:
First find how many MB in a day.
16,000 / 12 = 1333.3
Now find how many MB in one hour by dividing 1333.3 by 24 (b/c there are 24 hours in a day).
1333.3 / 24 = 55.5
Round 55.5 to 56
Let the numerator = x. Then,
The fraction is x/(3x+4).
If both the numerator and denominator are increased by 4, the fraction will be (x+4)/(3x+8), which, according to the question is equal to 9/25. So,
(x+4)/(3x+8) = 9/25
25(x+4) = 9(3x+8)
25x + 100 = 27x + 72
2x = 28
x = 14
Thus, the numerator is 14 and the denominator is (3*14 + 4), which is equal to 46. So the fraction is 14/46.
Is equal to 19 u add the 9 plus the ten so u get 19
