<h3>Given</h3>
Three numbers are n, 8n, and (100+n).
Their total is 690.
<h3>Find</h3>
the three numbers
<h3>Solution</h3>
n + 8n + (n+100) = 690
10n + 100 = 690 . . . . . . . simplify
10n = 590 . . . . . . . . . . . . subtract 100
n = 59
8n = 472
n +100 = 159
The three numbers are 59, 472, and 159.

Answer:
Dimensions of photo excluding border:
x = 11 inches
y = 6 inches
Step-by-step explanation:
Let the length be 'x' and width be 'y'.
The width of a photo is 5 inches less than its length, that is:
x-5 = y
let 'X' be length of photo including border and 'Y' be the width of photo including border:
Where X = x+2 and Y = y+2
Now , we have X-5 = Y
and X*Y = 104 square inches
*putting Y = X-5*
X(X-5) = 104



⇒ X-13 = 0 or X+8 = 0
Hence X = 13 or X = -8
As length can not be negative, X = 13 inches
Y = X-5 = 13-5 = 8 inches
Dimensions of photo excluding border:
x = X - 2 = 13-2 = 11 inches
y = Y-2 = 8-2 = 6 inches
