Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>

Answer: 5 feet and 7 inches
Step-by-step explanation:
"Give yourself 100 pounds for the first 5 feet plus 5 pounds for every inch over 5 feet tall"
100 pounds for 5 feet + 5 pounds/inch [over 5 feet]
We can separate 135 pounds into two parts: the first 100 pounds and the other 35 pounds: 135 = 100 + 35
100 = 5 feet
35 pounds/5 pounds/inch = 7 inches
So, the height is 5 feet and 7 inches
B. triangle ABC is isosceles. The angles add up 180 degrees.
