Write an equation y is 20% what is x

Mathematics
1 answer:
lisabon 2012 [21]2 years ago
4 0

Answer:

x + .20 = 1

Step-by-step explanation:

The equation would be x + .20= 1, or 1.00, because if you turn 20% into a decimal, it becomes .20. The total you are trying to find is 1 whole, in which this case it would simply be one as there is no other information. The x is first as if you had the .20 first, you would have to divide each side by .20, which would make x = 5, and that would not make sense.

Finding X: To find, subtract on each side by .20 due to the fact you are adding and need to do the opposite, .20-.20 cancels out and 1.00-.20 is .80, so you are left with x=.80

never [62]
Let the average of the other nine cities be x, then the population of the nine districts is 9x. The total population of the city is a + 9x. But a = 3x. Hence, the total population is 3x + 9x = 12x.
Therefore, the percent of the city's population living in district a is 3x/12x * 100 = 25%
