The length of a rectangular mailing label is 2 centimeters less than twice the width. The perimeter is 68 centimeters. Find the dimensions of the label.

Width=12 cm

Length=22 cm

Step-by-step explanation:

Let the width be x

Length= 2 cm less than twice the width

=2x-2

Perimeter of a rectangle=2(length+width)

68=2{(2x-2)+x}

68=2(2x-2+x)

68=2(3x-2)

68=6x-4

68+4=6x

72=6x

Divide both sides by 6

72/6=6x/6

12=x

Width=12 cm

Length=2x-2

=2(12)-2

=24-2

=22 cm

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
