Step-by-step explanation:
The Equation is 6( x+ 8.5) = 4( 2x+ 6.5)
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Case 1:
Total Friends = 6
so, the total Cost would be 6( x+ 8.5)
Case 2:
Total Friends = 4
so, the total Cost would be 4( 2x+ 6.5)
Hence, the Equation is 6( x+ 8.5) = 4( 2x+ 6.5).

A train leaves at 14.54 and arrives at its destination at 15.47. If the train travelled 66 km, what was it's average speed in km/h? Give your answer rounded to 1 dp. step by step explanation
Answer: average speed of the train = 4,483.0 km/h
Step-by-step explanation:
Speed = Distance / Time
Distance = 66 km
Time = 15.47 cancelling 15, we have 60 sec added to 47 sec
- 14.54
= 14. 107 60 + 47
- 14. 54
53secs
53secs to hours becomes =
60 secs = 1 min
60 min= i hour
therefore 53seconds =53/3600=0.0147222hours
Speed= 66/ 0.0147222= 4,483.025
Rounding to 1 dp becomes= 4,483.0 km/h

If Stevie can swim 16 laps in 4 minutes, how many can she swim each minute?
how do i figure out prime numbers
Answer:
You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

the slope of the line through each pair of points 1) (-14,-7) , (5,-4)
Answer:
m=3/19
Step-by-step explanation:
Find the slope between 2 points:
(x1,y1)=(-14,-7)
(x2,y2)=(5,-4)
First you would use the slope Formula:
m= y2,-y1/x2,-x1
=-4--7/ 5--14
=3/19

Can someone plz help me with this and explain how to do this math problem
Answer:
greater
Step-by-step explanation:
the reason is because if you allow x to have a value that is less than 3,
[tex] \sqrt{x - 3} [/tex]
will produce a square root of a negative number, and the square root of a negative number requires the use of imaginary numbers, therefore limiting x to greater than or equal to 3 prevents this, also, consideration should be given to the fraction
[tex] \frac{3}{x + 2} [/tex]
if x has a value of -2 it causes the denominator of the fraction to be 0, the denominator should never be 0, by limiting x to greater than 3 to prevent the problem above you are already taking care of x not being able to be -2 since greater than 3 already excludes -2

mr. Murphy's Megan graph to show his class the amount of water person consumes from food and beverages over time.
a person consumes 12 gallon of water each day (i already answerd this part)
(this part is the one im asking about )
complete the equation to show the relationship between X the number of days and Y the amount of water consumed
Y = ? X
Answer:
y = 12x
Step-by-step explanation:
From the question, we are told that a person consumes 12 gallons of water each day
Now, we want to complete an equation
From the question, x is the number of days and y is the amount of water consumed
Thus, mathematically, we have the equation as;
y = 12x
since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on
So the amount of water depends on rate number of days
Answer:
12

Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa .
-Abby walks at a speed of 8 feet per second.
-Melissa walks at a speed of 9 feet per second.
Abby had been walking for BLANK seconds when both students had walked exactly the same distance. (round to the nearest whole)
please help me
Answer:
270 seconds
Step-by-step explanation:
Melissa's time = x seconds
Abby's time = (x + 30) seconds
Abby walks at a speed of 8 feet per second, and Melissa walks at a speed of 9 feet per seconds.
But, speed = [tex]\frac{distance}{time taken}[/tex]
For Abby,
8 = [tex]\frac{distance}{(x + 30)}[/tex]
distance = 8(x + 30) ................. 1
for Melissa,
9 = [tex]\frac{distance}{x}[/tex]
distance = 9x ............. 2
From equations 1 and 2, for the same distance;
8(x + 30) = 9x
8x + 240 = 9x
x = 240 seconds
Abby's time = (x + 30)
= (240 + 30)
= 270 seconds
So that Abby has been walking for 270 seconds when both students had walked exactly the same distance.
The time taken is 270 seconds.
Given that,
Two students, Abby and Melissa go for a walk. Abby begins walking 30 seconds earlier than Melissa . Abby walks at a speed of 8 feet per second. Melissa walks at a speed of 9 feet per second.Here we assume Melissa time be x and Abby time be x + 30Based on the above information, the calculation is as follows:
8(x + 30) = 9x
8x + 240 = 9x
x = 240
So Abby time should be
= 240 + 30
= 270
