16 feet perimeter 5 feet long what is the width
miskamm [114]
P=2L+2W
L=Length
W=Width
P=Perimeter=16
So you have:
16=2×5+2w
Multiply 2 and 5 and get:
16=10+2w
Subtract 10 from both sides and get:
6=2w
Divide by 2 and get:
3=W
The width is 3.

A pet survey found that the ratio of dogs to cats is 2/5. Write and solve a proportion that shows the number of dogs
Irina18 [472]
So,

The ratio of dogs to cats:
\frac{2}{5}

The other proportion:
\frac{x}{140}

\frac{2}{5} =  \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1
\frac{2}{5} * \frac{28}{28} =  \frac{56}{140}

There are 56 dogs when the number of cats is 140.
