Answer : $77.40

Step by step explanation:

Set up a proportion.

72 • 7.5 = $540

540 / 100 = $5.40

The tax is $5.40.

Now you add the tax to the subtotal.

5.40 + 72.00 = 77.40

The total amount is $77.40.

Complete the equation to represent finding x, the greater integer.<br><br> x(x – ) = 143
mart [117]

Answer:

x would equal -11 or 13

Step-by-step Explanation:

x(x - 2) - 143 = 0

x^2 - 2x - 143 = 0

-2x + x^2 = 143

-143 + (-2x) + x^2 = 0

(x - 13)(x + 11)

x - 13 = 0

Add 13 to both sides

x = 13

x + 11 = 0

Subtract 11 from both sides

x = -11

The perimeter of rectangle living room is 40 m the living room is 10 m wide what is the length of the living room
Yuri [45]

Answer:

Width of the room = 5 meters

Step-by-step explanation:

the rectangular living room is calculated as length * width

The area is given to be equal to 40 sq. meters (area = 40 sq. meters)

Let the width = x meters

Length = X+3 meters

Area = Length * Width

40 = X * (X+3)

40 = X^2 + 3X

We solve this quadratic equation

So x = 5 or x= -8

Width  cannot be negative, so we reject x =-8

So x = 5 is the answer
