<span>1). 16 x 3/4 Step One- 16/1 x 3/4 Step two- 4 goes into 16 four times so cancel the 4 and change the 16 to a 4... Step three- 4 x 3=12 2). (81/16) divided by (9/14) Step one- Since its division we use (FREEZE CLAP FLIP)= Freeze (81/16) Clap the division sign and change it to a multiply sign and Flip the riprocals (9/14) The equation is now 81/16 X 14/9 Next 81 is divisible by 9 and 16 and 14 are divisible by 2 So the new formula i s 9/8 X 7/1 Solution=63/8 3). 2/3 divided by 4/3 Flip the reciprocals for the 4/3 New equation is 2/3 X 3/4 2 and 4 are divisible by 2 and the 3's cancel each other out Solution: 1/2</span>

The perimeter of a rectangle is 700 yards. What are the dimensions of the rectangle if the length is 50 yards more than the​ wid
Nataly [62]

Answer:

width = 150 yards

length = 200 yards

Step-by-step explanation:

Using the information given to us, we can make the following two equations:

2L + 2W = 700

L = W + 50

where L is the length in yards and W is the width in yards. This could treat these two equations as a system of linear equations. There are multiple ways to solve a system of linear equations, but I am going to solve this by substitution. Before doing that, I am first going to simplify the first equation, as it will make solving the system easier.

2L + 2W = 700

Divide both sides by 2.

L + W = 350

Since L = W + 50, we can substitute W + 50 for L in the equation L + W = 700.

(W + 50) + W = 350

2W + 50 = 350

2W = 300

W = 150

Now that we found what W is, we can solve for L by plugging 150 into either one of the equations. I am going to plug it into the equation L = W + 50.

L = 150 + 50

L = 200

Now we found what L is. So now we know that the width is 150 yards and the length is 200 yards.

I hope you find my answer and explanation helpful. Happy studying. :)
