Answer:
57 years old
Step-by-step explanation:
- 400 - 3x = 229
- 3x = 171
- x = 57
- 400 - 171 = 229
Answer: 900
Step-by-step explanation: To answer this question it has to be assumed that it is a regular polygon ie with equal angles.
Sum of the interior angles = (7-2)*180 = 5*180 = 900 degrees
So each interior angle = 900/7 = 128.57 degrees.
Answer:
5x - y = 27
Step-by-step explanation:
Slope is the direction of line and it is calculated as,
where (x₁, y₁) is any two points on the line.
Here, we have given that
Slope = 5 and (x₁, y₁) = (5, -2)
∴
⇒ 5(x - 5) = y + 2
⇒ 5x - 25 = y + 2
⇒ 5x - y = 27
Hence, the equation of a line is: 5x - y = 27
