Find the value of b if the graph of the equation y = -5x + b goes through the G(4,3) point.
Answers
Answer:
The Value of b is 23
Step-by-step explanation:
substitute 4 for x, and 3 for y. Then move combine like terms.
3 = -5(4) + b
3 = -20 + b
23 = b
3 = -5(4) + b
3 = -20 + b
add 20 on both sides
23 = b
now they know I don't know math

On a round trip over the same roads, Sophia averaged 24 mi/hr going and 30 mi/hr coming back. If the whole trip took 13.5 hours, what is the distance one way? (Hint: Find the time for each part of the round trip)
Answers
Answer:
d = rt. In this problem we are looking for the distance, but we will have to go about it indirectly. If she's traveling the same exact road going and returning, then the distance traveled both ways is exactly the same. Since d = rt, and d is the same, by the substitution property, if and , then , and . So we need to rt for the trip going, rt for the trip returning and set them equal to each other and solve for t. Going is a rate of 24, and the time is t (since we don't know t), and returning is a rate of 30, and the time is 13 1/3-t. (If the whole trip takes 13 1/3 hours, and t is the time going, then the time returning is the difference between the total time and the going time. That concept is one that baffles most algebra students!). So our r1t1 is 24t, and our r2t2 is 30(13 1/3 - t). Set them equal to each other and that will look like this: That fraction of 40/3 is 13 1/3 made into an improper fraction. Distributing that we will have and 54t = 400. That means that t = 7.407. We have time, and that's great, but we need distance! Go back to one of your equations for distance and sub in t and solve for d. d = 24t, and d = 24(7.407), so d = 177.768 miles.

Question 2: 20ft
Horse a travels 32 feet per second and horse b travels 28 ft per second. To find how far they Travis’s after 5 seconds you multiply by 5 because 1 (second) x 5 is 5 seconds
Horse a: 32 x 5 = 160
Horse b: 28 x 5 = 140
To fin how much further horse a tracked subtract.
160 - 140 = 20
So horse a traveled 20 more ft
Question 3: 80 nickels, 120 dimes, and 300 quarters
For every 2 nickels there are 3 dimes and for every 2 dimes there are 5 quarters
Let the number of nickels be n. Then the number of dimes is 3/2 n. There are 5/2 as many quarters as dimes, so there are 5/2 * 3/2 = 15/4 as many quarters as nickels = 15/4 n thus the number of nickels, dimes and quarters is
n + 3/2 n + 15/4 = 4/4 n + 15/4 n = 25/4 n
25/4 n = 500
n = 500 * 4/25 = 80
d = 3/2 n = 3/2* 80 = 120
q = 15/4 n = 15/4 * 80 = 300
So
80 nickels, 120 dimes, and 300 quarters
How much are the coins in the piggy bank worth?
Nickel = 5 cents
Dime = 10 cents
Quarter = 25 cents
4 quarter make a dollar so divide the # of quarter by 4
300 divided by 4= $75
20 nickels make a dollar so divide the # of nickels by 20
80 divided by 20 = $4
10 dimes make a dollar so divide the # of dimes by 10
120 divided by 10= $12
Add
75 + 4 + 12 = $91
Do the answer to part be is $91
Question 4: $51.96
If 3 books is 12.99 we need to find out how much one is. So we divide 12/89 by 3
12.99 divided by 3 = 4.33
So one book is $4.33. Now we need to find out how much 12 books cost. So multiply 4.33 by 12.
4.33 x 12 = $51.96

To avoid a storm, a passenger-jet pilot descended 0.38 mile in 0.4 minute. What was the plane's average change of altitude per minute?
Answers
Answer:
0.55 mile / minute
Step-by-step explanation:
The average change of altitude per minute would simply be the ratio of distance descended over time. That is:
average change of altitude = distance / time
average change of altitude = 0.44 mile / 0.8 minutes
average change of altitude = 0.55 mile / minute
