Answer:
52 units
Step-by-step explanation:
Perimeter = sum of it sides =
15 + 8 + 6 + 17 + 6
= 52
The answer to this question is 79 over 100.
They can buy any number of chairs fewer than four because 140-60=80
80 divide by 20 is 4
First thing to do is find out the coordinates of two points on the graph (I will use the ones that have been marked by the red dots):
Point A: (3, -1)
Point B: (1, 2)
Then we will use the slope formula to work out the slope:
y₂ - y₁ / x₂ - x₁
Substitute in our points:
2 - (-1) / 1 - 3
Then we work out the expression (remember a negative and a negative make a positive!):
3 / -2
Then we check if we can simplify this fraction, which in this case we cannot.
Therefore the slope of that line would be:
3 / -2
(remember to write it as a fraction!)
12 is indeed the correct answer to this problem
