Answer:
The average speed of Marshall is 29.7 mph
Step-by-step explanation:
Given;
distance traveled to work, d₁ = 27 miles
distance traveled back home, d₂ = 27 miles
initial time taken, t₁ = 1 hour and 20 minutes
final time taken, t₂ = 29 minutes
Total distance traveled, d = d₁ + d₂ = 27 miles + 27 miles = 54 miles
Total time taken for the journey, t = t₁ + t₂ = 1 hour + ( 20 mins + 29 mins)
t = 1 hour + 49 mins = 1 hour + 0.817 hour = 1.817 hour
The average speed is given by;
v = total distance / total time
v = 54 miles / 1.817 hour
v = 29.7 mph
Therefore, the average speed of Marshall is 29.7 mph
Each pretzel is 4.5 $
1.50 • 5 = 7.5
7.5 - 30 = 22.5
22.5 / 5 = 4.5
so in conclusion, those are some expensive a** pretzels.
Probability is defined as the <u>likelihood or the certainty</u> that an event is going to<u> occur or happen.</u>
The probability of randomly choosing a red and then a green marble is 
.
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
<u>The probability of choosing a red marble</u> = Number of red marbles / Total number of marbles
= 5/20
<u>In simplest fraction form</u> = 
We are told in the question that you keep the red marble you choose, So this means the <u>total number of marbles</u> left reduces to 19
<u>The probability of choosing a green marble is</u> = Number of green marbles / New total number of marbles
= 3/19
Therefore, <u><em>the probability of randomly choosing a red and then a green marble is </em></u>
P (Red) x P(Green)
= 1/4 x 3/19
=

Answer:
its y=-5x
Step-by-step explanation:
Why?
linear functions have only the slope, they dont include the y-intercept
Answer:
Infinite Solutions
Step-by-step explanation:
3(5x - 4) needs to be simplified
So we multiply 5x by 3
So 3 x 5x = 15x
Then we multiply -4 by 3
3 x -4 = - 12
Put those together we get 15x - 12
The same equation as the one on the right side
So since 15x - 12 = 15x - 12, the x variable can be any number
