p = 2l + 2w
P=Perimeter
L=Length
W=Width

Hints given are P= 76, L=20 so 2L=40

76=40+2w
76-40=2w
36=2w
18=w

The formula of a perimeter of a rectangle:

P = 2(w + l)

We have P = 76 cm and l = 20 cm.

Substitute:

2(w + 20) = 76       <em>use distributive property</em>

(2)(w) + (2)(20) = 76

2w + 40 = 76     <em>subtract 40 from both sides</em>

2w = 36       <em>divide both sies by 2</em>

w = 18

<h3>Answer: the width = 18 cm</h3>

Answer:

1(5/16)=1.3125

7(5/16)=7.3125

26(5/16)=26.3125

Step-by-step explanation:

Given that 5/16=0.3125, the mixed fraction 1(5/16)=1+(5/16)=1+0.3125=1.3125

Also, 7(5/16)=7+(5/16)=7+0.3125=7.3125

Furthermore,

26(5/16)=26+(5/16)=26+0.3125=26.3125

In the same vein, given that 4/15=0.266

1(4/15)=1+(4/15)=1+0.266=1.266

17(4/15)=17+(4/15)=17+0.266=17.266

23(4/15)=23+(4/15)=23+0.266=23.266
