What is the solution of 2x-y=9
Sedaia [141]
<span>Simplifying 2x + -1y = 9 Solving 2x + -1y = 9 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'y' to each side of the equation. 2x + -1y + y = 9 + y Combine like terms: -1y + y = 0 2x + 0 = 9 + y 2x = 9 + y Divide each side by '2'. x = 4.5 + 0.5y Simplifying x = 4.5 + 0.5y

Hope this helps :)

How much of the backyard is NOT being used for a vegetable garden or pet exercise area?
Nimfa-mama [501]

Area of backyard is not being used 7792 square feet.

Solution:

Length of the backyard = 181 ft

Width of the backyard = 48 ft

Area of the backyard = length × width

                                   = 181 × 48

Area of the backyard = 8688 square feet

Base of the triangle = 16 ft

Height of the triangle = 28 ft

Area of the triangle = \frac{1}{2}\times \text{base}\times \text{height}

                                 $=\frac{1}{2}\times {16}\times {28}

Area of the triangle = 224 square feet

Length of the rectangle = 32 ft

Width of the rectangle = 21 ft

Area of the rectangular vegetable garden = length × width

                                                                      = 32 × 21

Area of the rectangular vegetable garden = 672 square feet

Area of backyard not used

       = Area of backyard – Area of the triangle + Area of the rectangle

       = 8688 – 224 – 672

       = 7792 square feet

Area of backyard is not being used 7792 square feet.
