Answer:
box 1, 4 and 5 are correct
Step-by-step explanation:
Box 1 is correct if you simplify the equation by multiplying both sides by 4. When you multiply the left side by 4 you end up with 56 + 8x since 4 times [tex]\frac{1}{4}[/tex] equals 1. The right side becomes 4 x 20 = 80. So 56 + 8X = 80. If you continue to solve for X, you first have to subtract 56 from both sides of the equal sign which looks like this: 56 - 56 + 8X = 80 - 56 which reduces down to 8X = 24. Dividing both sides by 8 then reduces that equation down to X = 3.
Box 4 is also correct. When you have an equation like [tex]\frac{1}{4}[/tex] (8x + 56), you have to multiple both numbers on the inside of the parentheses by the number on the outside of the parentheses. So the equation is ([tex]\frac{1}{4}[/tex] X 8x) + ([tex]\frac{1}{4}[/tex] X 56) which results in 2x + 14. The right side of the equal sign does not change so now you have
2x + 14 = 20. To get rid of the 14 on the left, you subtract 14 from both sides.
2x + 14 - 14 = 20 - 14. On the left, 14-14=0 so you end up with just 2x. On the right 20-14=6. So now you have the equation 2x = 6. If you continue to solve for x, you divide both sides of the equal sign by 2. This will give you x = 3. Same as what you get by solving for x in Box 1 above.
Box 5 is also correct. As you see above when you solve for X in both answers above, X = 3.

A plumber charges a $50 fee plus $100 per hour to complete a plumbing job. The total amount spent on a plumbing job can be expressed by the function T(x) = 100x + 50 where x represents the number of hours spent on the plumbing job. The maximum time spent on one job per day is 8 hours. Find a reasonable domain and range for this situation.
Answer:
Between 150 and 800
T is between 150 and 800
Step-by-step explanation:
given information
charges=$50
charges per hour=$100
let the amount of time spent be x
therefore the function for the total amount is
T(x) = 100x + 50
we want to estimate the amount for 1 hour and 8 hours
for 1 hour we have
x=1
T(x) = 100x + 50
T(1) = 100(1)+ 50
T(1) = 150
for 8 hours we have
x=8
T(x) = 100x + 50
T(8) = 100(8)+ 50
T(8) = 800+50
T(8) = 850
the domain is between 150 and 800

Your first job is to babysit a couple of times a week. You charge a flatfee of $10 for transportation back and forth to the house plus $5.50per hour. Let t be the time in hours that you babysit. Write analgebraic expression to define the amount of money you will makefor t hours of work.
Answer:
5.50t + 10
Step-by-step explanation:
Total amount of money made will sum of
transportation fees and money charged for t hours of baby siting
Given
transportation fees of back and forth to the house = $10
also given that
fees of 1 hour babysitting = $5.50
we have to find fee for t hours baby sitting ,
fees of t hours babysitting = fees of 1 hour babysitting*t
fees of t hours babysitting = 5.50t
Total amount of money made = fees of t hours babysitting + transportation fees of back and forth to the house
Total amount of money made = 5.50t + 10
Thus,
algebraic expression to define the amount of money you will make for t hours of work is 5.50t + 10

A model train is traveling at a constant rate of 0.75 meter per second when Rebecca starts a stopwatch. Select the graph that represents the relationship between t, the amount of time since Rebecca started her stopwatch, and d, the total distance the train has traveled during that time.
Answer:
See Explanation
Step-by-step explanation:
Given
Rate = 0.75m/s
d = distance
t = time
Required
Select the graph that represents the given relationship
The option showing the graphs is missing. So, I'll answer the question from scratch.
We have that.
Rate = d/t (i.e. distance/time)
Substitute 0.75 for Rate
0.75 = d/t
Make d the subject
d = 0.75t
To plot the graph, we assume values for time (t)
Take t = 1
d = 0.75 * 1
d = 0.75
Take t = 6
d = 0.75 * 6
d = 4.50
So, we'll plot the graph at points
(1,0.75) and (6,4.50)
