Hi friends!!who gives the answer is the best!!!!
A car covers a distance 50km in 2.2 hrs what is the average distance cover it in 1 hour?
Answers
Answer:
22.73 km.
Step-by-step explanation:
To find the average distance covered by the car in 1 hour, we can use the concept of speed or velocity.
Speed is defined as the distance traveled divided by the time taken. In this case, the car covers a distance of 50 km in 2.2 hours.
To find the average speed of the car, we divide the total distance by the total time:
Average speed = Total distance / Total time
Average speed = 50 km / 2.2 hours
Simplifying this calculation, we find that the average speed of the car is approximately 22.73 km/h.
Since speed is defined as the distance covered per unit of time, we can conclude that the car covers an average distance of 22.73 km in 1 hour.
Therefore, the average distance covered by the car in 1 hour is approximately 22.73 km.

Hi there
5x+3(x-5)=6x+2x-15
Simplify both sides of the equation
5x+3(x-5)=6x+2x-15
Distribute
5x+3x-15=6x+2x-15
Combine like terms
(5x+3x)-15= (6x+2x)-15
8x-15=8x-15
Subtract 8x from both sides
8x-15-8x=8x-15-8x
-15=-15
Add 15 to both sides
-15+15=-15+15
0=0
All real numbers are solutions
To solve this equation I used " The distributive property"
I hope that's help !

The answer to your question is x = 36, y = 11
Step-by-step explanation:
Data
there are 2 numbers
their sum is 47
one is larger by 25
x is the larger
y is the smaller
Process
1.- Write two equations that help to solve this problem
x + y = 47 Equation l
x = y + 25 Equation ll
2.- Solve the system of equation by substitution. Substitute Equation ll in equation l
(y + 25) + y = 47
-Solve for y
y + 25 + y = 47
2y = 47 - 25
2y = 22
y = 22/2
y = 11
- Find x, substitute y in equation ll
x = 11 + 25
x = 36
Answer: the smaller number is 11. The larger number is 36
Step-by-step explanation:
Let x represent the larger number.
Let y represent the smaller number.
The sum of the two numbers is 47. It means that
x + y = 47- - - - - - - - - - -1
If the larger number is 25 more than the other number, the expression would be
x = y + 25
Substituting x = y + 25 into equation 1, it becomes
y + 25 + y = 47
2y + 25 = 47
2y = 47 - 25
2y = 22
y = 22/2
y = 11
x = y + 25 = 11 + 25
x = 36

The whole number are the natural numbers plus 0: 0, 1, 2, 3, . . .
The irrational numbers are the numbers which cannot be expressed in the form a/b where a and b are integers. They are usually in the form of a non recurring and non terminating decimals.
The integers complices of both the negative and the positive whole numbers.
