The constant of proportionality of our given tables is; 5.
<h3>How to find the constant of Proportionality?</h3>
We are given that x and y are proportional, and this means that:
y = r*x
where;
r is the constant of proportionality.
We are given the table;
x y
7 35
12 60
20 100
Now, we can replace those values in our equation and get, for the first pair: 35 = r*7
r = 35/7 = 5
For the second pair:
60 = r*12
60/12 = r
r = 5
Thus, we can conclude that the constant of proportionality is 5.

Answer:
See attached picture.
Step-by-step explanation:
Solve the inequality:
Graph the solution by placing a closed dot (or filled in dot) on 17 on the number line. This is closed or filled in since z is less than or equal to. Then for the less than part, shade to the left of 17.
1 mile/hour = 5280 feet/(60 x 60) seconds = 1.467 feet/second
25 miles/hour = 1.467 x 25 = 36.67 feet/second.
Answer:
6
Step-by-step explanation:
8x + 2 + 70 + 60 = 180 ( sum of all angles of a triangle = 180 degree )
8x + 132 = 180
8x = 180 - 132
8x = 48
x = 48 / 8
x = 6
Therefore 3 rd option is correct.
