Question 277644
Let one number be x

The other number is 3 more than 2x = 2x+3

x+2x+3=27

3x=27-3

3x=24

x=24/3 
=8

The other number is 19


Let the width be x

the length = 3times the width = 3x


perimeter = 2x+2*3x

2x+6x=22

8x=22
x=22/8
x=2.75

Length = 3*2.75 =8.25












Let the odd number be x

The next odd number will be x+2

Their sum =92

x+x+2=92

2x+2-92

2x=92-2
2x=90

x=90/2 
=45

the other number will be 47



Let the number be x

The other number is 800 less than 3times x

3x-800

x+3x-800=1200

4x-800 =1200

4x=1200+800

4x=2000/4

x=500

The other number 1200-500 = 700
