Answer:
D. 8.57
Step-by-step explanation:
Okay I'm not sure if I do these problems correctly, but I always get the right answer.
7/11 = 0.6363...
15/0.6363... = 23.5714...
23.5714...- 15 = 8.57
Use the distance formula!
d = square root of (x2-x1)^2 + (y2-y1)^2
=19.4165
Answer:
4 and 5
Step-by-step explanation:
Let the numbers be x and y
If their sum is 9, hence;
x + y = 9 ....1
When reversed
10y+x = 2(10x+y)
10y+x = 20x + 2y
10y - 2y = 20x - x
8y = 19x
y = 10x/8 ...2
Substitute equation 2 into 1;
From 1;
x+y = 9
x +(10x/8) = 9
18x/8 = 9
18x = 72
x = 72/18
x = 4
Since x+y =9
y = 9-x
y =9-4
y = 5
Hence the numbers are 4 and 5
