HELP ASAP NOW NOW NOW NOW!!! Suppose three riders rode a total of 182 miles.
If they used a total of 13 horses, and rode each horse the same number of miles, how many miles did they ride before replacing each horse?
They rode _____ miles before replacing each horse.
Answer:
14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles / 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.

A machine can make 56 parts in 4 hours. It
can also make 70 parts in 5 hours. Write an
equation that relates the number of parts
the machine can make and the time in
hours. Predict how many parts the machine
can make in 9 hours, 30 minutes.
Answer:
133
Step-by-step explanation:
56/4=14 and 70/5=14. 14 x 9 = 126
30 mins is half of an hour which means you need to divide 14 by 2 which gives you 7.
126 + 7 = 133
133 parts the machine can make in 9 hours, 30 minutes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A machine can make 56 parts in 4 hours.
56=4x
A machine can also make 70 parts in 5 hours.
70=5x
Now we need to write an equation that relates the number of parts
the machine can make and the time in hours.
14=x
Now, we need to find parts the machine can make in 9 hours, 30 minutes.
14 x 9 = 126
As 30 minutes is half an hour, so divide 14 by 2 we get 7
126 + 7 = 133
Hence 133 parts the machine can make in 9 hours, 30 minutes.

Part A: Explain how to sketch the graph of a curve that opens downwards and has only one x-intercept at (2.5,0).
Part B: Explain how to sketch the graph of a curve that opens upwards where the minimum value of the graph is (0,1).
Part C: Explain how to sketch the graph of a curve with the following characteristics.
• The graph opens downward.
• The y-intercept is (0,6).
The z-intercepts are (-1,0) and (3, 0).
• The maximum value of the function is located at the point (1,8).
Part A:
If a quadratic has only one x-intercept, then that is where the vertex lies. being that the vertex is the highest or lowest point in the quadratic. To sketch, it will open downwards with a single x-cept
Part B:
The graph will be above the x-axis. And having the vertex being at (0,1) as it says its the minimum value. All the minimum means is that its the lowest value of this given parabola.
Part C:
Plot the points of the y-intercept and z-intercepts. Then plot the maximum value is. Connect the dots.

what is the unit rate of 1/4 kilometer in 1/3 hour
Answer:
3/4 km in 1 hour
Step-by-step explanation:
You divide to find unit rate.
1/4 divided by 1/3 is
1/4 x 3/1 = 3/4
3/4 kilometers in 1 hour
Hope this helps :)
The required rate of 1/4 kilometer in 1/3 hour is 3 / 4 Kilometer per hour.
Given that,
To determine the unit rate of 1/4 kilometer in 1/3 hour.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
What is the rate of change?The rate of change is defined as the change in value with the rest of the time is called rate of change.
Here,
The unit rate of 1/4 kilometer in 1/3 hour,
Rate = (1 / 4 kilometer) / (1 / 3 hour)
Rate = 1 / 4 / 1 / 3
Rate = 3 / 4 Kilometer per hour.
Thus, the required rate of 1/4 kilometer in 1/3 hour is 3 / 4 Kilometer per hour.

When the function y=x is changed to y=|x|, how is the graph affected?
A. All points for x 0 are reflected over the line y=x.
B. All points for x 0 are reflected over the line y=x.
D. All points for x > 0 are reflected over the x-axis.
Answer:
First, the function:
y = x
Is:
Positive if x > 0
Negative if x < 0
Now, on another hand, the function y = IxI is:
Positive if x < 0
Positive if x > 0.
Then the only part that changes is the negative side of the domain, and the thing that changes is the sign (the change of sign is equivalent to a reflection over the x-axis or the line y = 0".
Then the correct option is:
"All points for x < 0 are reflected over the x-axis"
I suppose that this is option C, the missing one.

Really hard geometry problems. Please help!
Answer: For #3 the answer is 48 degrees, #4 is 70 degrees
Step-by-step explanation:
3. CGA and BGD are verticle angles which means they are congruent, and (2x-10)+(x+4)+(x+10) is 180. Which gives you X=44, then you substitute x into x+4 which gives you 48.
4. CEB and BED are supplementary which means they make up 180. BED and CEA are verticle angles which means they are congruent. We know CEB is 110 which means BED is 70 because 180-110=70. BED and CEA are verticle angles which means CEA is also 70 degrees
Answer:
i think #3 is 93 and #4 is 70
Step-by-step explanation:
a full circle is equal to 360
for #3, i used the equation (2x-10) + (x+4) + (x+10) = 360
combine all like terms and get 4x + 4 = 360
subtract 4 from both sides
4x + 4 = 360
4x = 356
divide 4 from both sides
x = 89. from here put 89 where x is . angle BGD and angle CGA are the same so 89 + 4 = 93
for #4, use the equation 45 + 3x - 19 = 110
combine like terms and get 26 + 3x = 110
subtract 26 from both sides and then divide by 3
3x = 84
x = 28
place 28 where x is and find the matching angle which is 70.

John's phone company offers 2 cell phone plans, A and B. Both plans offer 450 free minutes per month, but plan A charges $40 per month and $0.35 for each additional minute, while plan B charges $45 per month and $0.30 for each additional minute. Which inequality shows the number of minutes, x, that John may use in a month in order to make plan B the better plan for that month?
A.
40 + 0.35(x − 450) 45 + 0.30(x − 450)
D.
40 + 0.35x > 45 + 0.30x
Answer: 45 + 0.30(x-450) > 40 + 0.35(x-450)
Step-by-step explanation:
Given: Free minutes = 450
For plan A,
Fix charge = $40
Charge per minute after free minutes = $0.35
For plan B,
Fix charge = $45
Charge per minute after free minutes = $0.30
Let x be the additional minutes.
Charges according to plan A = 40 + 0.35(x-450)
Charges according to plan B = 45 + 0.30(x-450)
If plan B is better than plan A.
45 + 0.30(x-450) > 40 + 0.35(x-450)
Required inequality : 45 + 0.30(x-450) > 40 + 0.35(x-450)
Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirrels. The total number of animals she caught is ten more than four times the number of deer caught. How many rabbits did Katniss catch? Help steps
Answer:
10 rabbits
Step-by-step explanation:
Let us represent
Number of rabbits = x
Number of squirrels = y
Number of deer = z
Katniss caught three times as many squirrels as deer.
y = 3z
She also caught five less rabbits than squirrels.
y = x - 5
The total number of animals she caught is ten more than four times the number of deer caught.
x + y + z = 4 × z + 10
x + y + z = 4z + 10
How many rabbits did Katniss catch?
Number of rabbits = x
We make x subject of the formula
x + y + z = 4z + 10
x = 4z + 10 - y - z
y = 3z
x = 4z + 10 - 3z - z
x = 4z - z - 3z + 10
x = 4z - 4z + 10
x = 0 + 10
x = 10
Therefore, the number of rabbits Katniss caught is 10 rabbits

-3(8x-2)=9-21x Original equation
8x-2=-3+7x
8x+1=7x
1=-x
-1=x
Answer:
Below in bold
Step-by-step explanation:
-3(8x - 2) = 9 - 21x
~Divide -3 to everything
8x - 2 = -3 + 7x
~Add 3 to both sides
8x + 1 = 7x
~Subtract 8x to both sides
1 = -x
~Divide -1 to both sides
-1 = x
Note that this isn't the most used way to solve equations because you would typically use distribution to simplify the left side.
Best of Luck!
