Answer:

A. 1.2x = 78

B. x = 65

Step-by-step explanation:

Just informally, first:

x is the number that we don't know. 120% of that number is a number BIGGER than that number. 120% of x is 78. So 78 is BIGGER than the number that we don't know.

120% of x = 78

Change 120% to a decimal by moving the decimal two places to the left. Multiply.

1.2x = 78

To solve, divide both sides by 1.2

x = 78/1.2

x = 65

The perimeter of an ICU ward, that is rectangular in shape, is 258 feet. The width is 37 feet less than the length. Find the dim
zubka84 [21]

The dimensions of the rectangle is 83 feet x 46 feet

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P = 2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P = 2 ( Length + Width )

Given data ,

The perimeter P of the rectangle = 258 feet

Let the length of the rectangle be = L

Let the width of the rectangle be = W

And , The width is 37 feet less than the length. ,

So , W = L - 37

Perimeter P = 2 ( Length + Width )

Substituting the values of L and W in the equation , we get

Perimeter P = 2 ( L + L - 37 )

2 ( L + L - 37 ) = 258

( L + L - 37 ) = 129

2L - 37 = 129

Adding 37 on both sides , we get

2L = 166

Divide by 2 on both sides , we get

Length L of the rectangle = 83 feet

Substituting the value of L in equation ,we get

W = L - 37

Width W of the rectangle = 46 feet

Therefore , Length = 83 feet and Width = 46 feet

Hence , the dimensions of the rectangle is 83 feet x 46 feet

Annette [7]
The answer is 26.
This is because, since y is equal to 8, you would put 8 in replacement of y, which is called substituting. It would look something like this.
2 + 3y
2+ 3(8)
2+ 24
