We have been given an equation . We are asked to find constant of proportionality from our given equation.
We know that two directly proportional equations are in form ,where y is directly proportional to x and k is constant of proportionality.
Let us rewrite our given equation by cross multiplying as:
Now we will divide both sides of equation by 2.
We can see that our equation is in form and constant of proportionality is .

Step-by-step explanation:
Answer:
The total length of Valerie’s walls is 105.75 feet:
(2.5 × 4) + (21.25 × 3) + 32 = 10 + 63.75 + 32 = 105.75 feet.
The total length of Seth’s walls is 107 feet:
3.5 + (22.75 × 2) + 58 = 3.5 + 45.5 + 58 = 107 feet.
The sum of 105.75 feet and 107 feet is 212.75 feet. The Commutative Property allows me to add numbers in any order. This is why the answers in parts D and E match.

Answer:
32.5 miles
Step-by-step explanation:
Given that:
Eastbound bus :
0.8 miles every 45 seconds
Speed per second :
0.8 / 45 = 0.0177777 miles per second
Distance after 15 minutes
(15 * 60) * 0.0177777 = 16 miles
Westbound bus:
0.55 miles every 30 seconds
Speed per second :
0.55 / 30 = 0.0183333 miles per second
Distance after 15 minutes :
(15 * 60) * 0.0183333 = 16.5 miles
Distance apart :
16 miles + 16.5 miles = 32.5 miles
METHOD 2:
Distance covered after 15 minutes :
15 minutes = 15 * 60 = 900 seconds
Distance apart after 900 seconds :
[0.8 * (900/45)] + [0.55 * (900/30)]
16 + 16.5
= 32.5 miles
