Vertical angles are always Congruent.
Answer:
lol is this a test? are u cheating!!!!???
Step-by-step explanation:
First you want to collect the like terms, 2a=45 , then divide both sides of the equation by 2 which is a=2/5 , or a=0.4
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

Decimals and fractions are alike because all decimals are fractions and all fractions are decimals. As an example: 1/2, which is one-half, is the same as 0.5.
