A linear equation in the form y = mx + c has slope m Any line parallel to 3x + 9y = 5 has the same slope 3x + 9y = 5 → 9y = -3x + 5 → y = (-3/9)x + 5/9 → y = -⅓x + 5/9 & So it’s 10 and 0

Find the constant of variation
From the question, the variation is as follows



Convert variation to equation

Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t


Divide both sides by p



Substitute the values of p, r, s and t in the above equation


Divide numerator and denominator by 6

Hence, the constant of variation is; 
Answer:
42 degrees
Step-by-step explanation:
180-138 = 42
angles 1, 2, and 5 are all 139 degrees
angles 7, 3, 4, and 6 are 42 degrees
Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
