Answer:
x = 45, y = 5
Step-by-step explanation:
It is given that two lines form a linear pair with equal measures. Therefore, the angle between the two lines will be 90. Now, according to the question,
2x + 20y - 10 =90
2x+20y = 100
x + 10y = 50
And
2x = 20y-10
x = 10y -5
x - 10 y = -5
Now, adding x + 10y = 50 and x - 10y =-5, the value of x can be found. The required value will be:
x + 10y =50
x - 10y = -5
------------------
x = 45
Therefore, the value of y after substitution of the value of x in one of the equations will be:
90 = 20y - 10
20 y = 100
y = 5
Hence, the required value of x and y are 45 and 5 respectively.

Answer:
Mean: 50.8 or 51 (rounded)
Median: 51.5 or 52 (rounded)
Step-by-step explanation:
To find the mean I added all the numbers then divides my sum but the number of numbers.
To find the median I listed the numbers from least to greatest.There are two middle numbers so I added the two numbers and divided the same by 2.
The relationship being proportional means there is a value of k such that
... y = k·x
We are given the point (6 (pounds), 3 (dollars)), so we can write ...
... 3 dollars = k·6 pounds
Dividing by 6 pounds, we get
... (3/6) dollars/pound = k = $0.50/lb
Now, we can use x=1 pound to find the price (y),
... y = ($0.50/lb)·(1 lb)
... y = $0.50 . . . . the price of 1 pound of tomatoes.
