Some rectangles have an area of 36 cm². Let the variable W represent the width of these rectangles. Which expression represents
ZanzabumX [31]

Answer:

The perimeter of the rectangle is expressed as; P = \frac{72 \ + \ 2W^2}{W}

Step-by-step explanation:

Given;

area of the rectangle, A = 36  cm²

width of the rectangle, = W

Let L represent the length of the rectangle,

A = L x W

L = \frac{A}{W} = \frac{36}{W}

The perimeter of the rectangle is calculated as;

P = 2(L + W)

Substitute the value of L into the above equation;

P = 2(L + W)\\\\P = 2 (\frac{36}{W} + W)\\\\P = 2 (\frac{36 + W^2}{W} )\\\\P = \frac{72 \ + \ 2W^2}{W}

Thus, the perimeter of the rectangle is expressed as P = \frac{72 \ + \ 2W^2}{W}

A movie theater has a seating capacity of 153. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults.
Katena32 [7]

Answer:

x (children) = 58

y (students) = 66

z (adults) = 29

Step-by-step explanation:

Step 1: Write system of equations

x + y + z = 153

5x + 7y + 12z = 1100

1/2x = z

The best way to solve the systems of equations is to use an augmented matrix:

Top row: [1 1 1 | 153]

Middle row: [5 7 12 | 1100]

Bottom row: [1/2 0 -1 | 0]

And then put it in RREF form:

Top row: [1 0 0 | 58]

Middle row: [0 1 0 | 66]

Bottom row: [0 0 1 | 29]
