Step-by-step explanation:
A bus travels two different routes: the Green Route and the Blue Route. The routes are
different lengths.
• On Monday the bus traveled the Green Route 6 times and the Blue Route 5 times,
traveling a total of 52 miles.
• On Tuesday the bus traveled the Green Route 12 times and the Blue Route 13 times,
traveling a total of 119 miles.
What is the length of the Green Route in miles?
Set up a system of equations and say green route is x and blue route is y
This will give you
Monday 6x + 5y= 52
Tuesday 12x + 13y = 119
Solve by multiplying the top equation by two to get
12x + 10y= 104
Since you have 12x in both equations, these cancel out when you subtract the bottom from the top. This leaves you with
-3y=-15
Y=5
The blue route is 5 miles, but they want to know the green route. Fill in the y value in either one of your equations. Let’s use the one from Tuesday
12x + 13 (5) = 119
12x= 54
X= 4.5
This means that the answer is 4.5 miles
The length of the Green Route in miles is 4.5 miles.
Formulate an equation for Monday and Tuesday
Monday
6x + 5y= 52............Equation 1
Tuesday
12x + 13y = 119............Equation 2
Multiply the equation
12x + 10y= 104
-3y=-15
Divide both side by 3y
y=15/3
y=5
Plug in 5 into equation 2
12x + 13 (5) = 119
12x+65=119
12x=119-65
12x= 54
Divide both side by 12x
x=54/12
x= 4.5 miles
Inconclusion the length of the Green Route in miles is 4.5 miles.

I need help this is due today and i just need this one question. How can you find the unit rate or constant of proportionality for a relationship represented in a graph. I will give Brainleist.
Answer:
If the rate of change is yx , then so is the constant of proportionality. To simplify things, we set yx=k , where k represents the constant of proportionality. If you solve a yx=k equation for y, (like this: y=kx), it is called a direct variation equation.
1. The school office is now selling neon mechanical pencils. If the office pays $10.80 for a dozen pencils, how much should be charged to make a profit of 75 cents each?
2. Several cases of 16-ounce bottles of water were purchased for $252.00. If one case costs $7.00, how many cases were purchased?
3. Okolona College ordered jerseys to sell at the homecoming game. The college paid $9.25 each for 225 jerseys. Each jersey was sold for $15.75. What was the percent of markup for each jersey? How much profit was made if all of the jerseys were sold?
4. A truck traveled 654 miles on a long distance run. If the truck averaged 55 mph, how many hours did it take to reach the truck's destination? (Round to the nearest hour)
5. Della Riley borrowed $2400 for 6 months to invest in a business venture. If she agreed to pay 8% interest annually, how much will she be repaying?
6. It takes Dan an average of 45 minutes each evening to do his chemistry homework. Dan calculates that he worked a total of 3 hours on chemistry last week. Assuming that Dan worked his average time per evening consistently, how many evenings did Dan work?
7. Jon's car averages 20 mpg in town and 28 mpg on the road. What is the percent of decrease between the two driving conditions?
Answer:
1. Each pencil cost .90 cents each. So if they want to make a profit of 75 cents each they will get $9 for a dozen pencils. They must charge 75 cents.
2. Several means 4 but in this case, it means 36. When you divide 252 by 7 you get 36. Because each case is $7 and the total is 252.
3. The percent markup for each jersey was around 65%. They almost doubled the price by 6.50. They would make $3543.75 if they sold all the jerseys at the homecoming game.
4. The truck took 12 hours to reach its destination.
5. She would be repaying $ 1,152.00 in one year.

a. There are 24 hours in a day. Days = x, hours = y. 24 hours times the number of days = the total numbers of hours. I just built a table based off of that.
b. there are consistently 24 hours in a day, every day so it is constant.
c. 24 hours per day. total hours = 24 (number of days)

Patrick wants to rent a canoe and has a $15 coupon to use at Cool Canoes. The fee for canoe rental is $20.00 per hour. Which equation represents the total cost of renting a canoe, where c is the cost of renting a canoe and h is the number of hours it is rented?
h = 15 − 20c
c = 20h − 15
h = 20c + 15
c = 15h + 20
Answer:
c= 20h-15
Step-by-step explanation:
Trust me :)
Since its $20 an hour, the variable h represents the number of hours.
Then since he has a coupon for $15 off, then that needs to be subtracted because a coupon is used to save money.

Mr. Smith earns $15.50 per hour for the first 40 hours he works in a week. He earns 1 ½ times that amount per hour for each hour beyond 40 hours in a week. Last week Mr. Smith worked 48.5 hours. How much money did he earn?
Answer:
He earned $817.625
Step-by-step explanation:
It is pretty easy just 40 times 15.50 than keep that answer. than 15.50 times 1 1/2 than multiply the answer of that by 8.5 which is how much extra he worked than add the two big numbers which is 620.000 by 197.625 and you get 817.625.

The temperature was -5°F when Sally went to school on Monday. The temperature rose
20°F during the day, but fell 25°F during the night. A heat wave increased the
temperature 40°F on Tuesday, but then an arctic wind overnight decreased the
temperature 70°F! What was the temperature on Wednesday?
Answer:
-40
You start at -5 then you add 20 to get 15 . Then you subtract 25 from 15 to get -10. Then you add 40 to -10 to get 30. Then you have to subtract 70 from 30 to get -40 F.

Answer:
-40°F
