Answer: D = 5
explanation : i used pythagorean theorem to solve it and the answer is 5
Let the numbers be 7x and 4x
According to question
7x-4x =57
3x =57
X=57/3
X=19
So the numbers are
7x=7*19=133
4x=4*19=76
The answer for this question that needs an answer is n = 5
because 18(n-1) = 9(n+7) implies that 18n - 18 = 9n + 63 which implies that n =5 for the equation to hold true.
Hello from MrBillDoesMath!
Answer:
11/ 1009 (.0109 approximately)
Discussion:
99/9081 = => as 9081 = 9 * 1009 = 3 * 3 * 1009
99/ ( 3 * 3 * 1009) =
(99/(3*3)) * (1/1009) =
(99/9) * (1/1009) =
11/ 1009 =
.0109 approximately
Thank you,

Domain of a set of ordered pairs
We know the domain is the set of all x when is represented by ordered pairs: (x, y)
In this case {(-8,-12),(4,-8), (2, -10),(-10.-16) } we can observe that there are four x (the first number of each pair):
Domain = { -8, 4, 2, -10}
<h2>Domain = {-10, -8, 2, 4}</h2>
