X + 14 + x + 14 = 17 + x + 7
2x + 28 = 24 + x
2x - x = 24 - 28
x = -4
DF = x + 14
= (-4) + 14
= 10
10
The x’s represent just the people, and because the bottom line only represents time it doesn’t affect the amount of people.

just solve it and it will come out
Infinite sets may be countable or uncountable. Some examples are: the set of all integers, {..., -1, 0, 1, 2, ...}, is a countably infinite set; and. the set of all real numbers is an uncountably infinite set.
Step-by-step explanation:
45% of number = 180
=> 100% of number = 180 * (100/45) = 400.
Hence the number is 400.
