7) A. A variable is an unknown value, and x is unknown. Constants are known values so they cannot have X in it.
8)A again for the same reason as number 7
Using the equation of the proportional relationship:
Average rate of speed = 60
Time taken to go 300 miles = 5 hrs
Distance travelled in 2.5 hrs = 150 miles
<h3>What is a Equation of a Proportional Relationship?</h3>
A equation of a proportional relationship models the relationship between two variables, x and y, that has a constant of k. It is expressed as y = kx.
Given the following:
Equation: d = 60t
d = distance in miles
t = time in hours
Average rate of speed for the bus = k = 60
Time (t) it would take to go 300 miles (d):
300 = 60(t)
300/60 = t
t = 5 hours
Distance (d) it would travel in 2.5 hours (t):
d = 60(2.5)
d = 150 miles

Answer:
the last one
Step-by-step explanation:
its the last one because 1x3 is 3 so you need one with a 3, then 4x2 is 8 and theres half a side so its the last answer with half 3/4 on one side
