Answer:
-8x + 5y + 4
Step-by-step explanation:
- 6x + 5y - 2x + 4 Group like terms
-6x - 2x + 5y + 4
= - 8x + 5y + 4
First find the area of the whole pizza.
The formula for area of a circle is Area = PI x r^2
The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.
I will use 3.14 for PI since the problem doesn't say what value to use.
Area = PI x 65.5^2
Area = 3.14 x 4290.25
Area = 13,471.39 square feet
Divide the total area by the number of pieces:
13,471.39 / 50 = 269.43 square feet
To find the length of the crust first find the circumference of the whole pizza:
Circumference = PI x diameter
Circumference = 3.14 x 131 = 411.34 feet
Now divide the total by the number of pieces:
411.34 / 50 = 8.23 feet
Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.
Answer: D
Step-by-step explanation: Complementary angles add up to 90 degrees supplementary add up to 180 degrees and vertical angles are like CAF and DAE like how they're diagonal
Answer:
x ∈ All real numbers
Step-by-step explanation:
When the distributive property is applied to the left side, the parentheses can be eliminated and the equation becomes ...
-2x -6 = -2x -6
This is true for all possible values of x, "all real numbers".
Answer: y = 2x - 20
1. y + 18 = 2(x - 1)
2. y + 18 = 2x - 2
3. y + 20 = 2x
4. y = 2x - 20
