Let's call his secret number 'M' (for mystery-number).

multiplied it by 5 . . . 5M
subtracted 16 from the result . . . 5M - 16

adds 10 to the number . . . M + 10
multiplies that result by 3 . . .  3(M+10)

Both processes produce the same results:

                                             5M - 16  =  3 (M + 10)

Eliminate parentheses
on the right side:                 5M - 16  =  3M + 30

Subtract  3M 
from each side:                   2M - 16  =           30

Add  16  to each side:        2M          =           46

Divide each side by  2 :        M          =           23

The perimeter cf a rectangle i: 56 inches" the ratio of the length of the width is 6 : 1. Find the length and the width.
sergejj [24]

Answer: Length = 24; width =4

Step-by-step explanation

Since the ratio of the length to width is 6:1

Let the length  be represented as  6x

And the width be  = x

Such that that the Perimeter of the rectangle which is  

Perimeter = 2(length + width)  becomes

56 = 2(6x + x)

56/2 = 6x+x

28 = 7x

x = 4

Width = 4

Length = 6x= 6 x 4 = 24
