Answer:
- x = x+1
- 0 = x+1
- x+1 = x+1
Step-by-step explanation:
1. There will be no solution if the equation is a contradiction. Usually, it is something that can be reduced to 0 = 1.
If we choose to make our equation ...
x = x +1
Subtracting x from both sides of the equation gives ...
0 = 1
There is no value of the variable that will make this be true.
__
2. Something that reduces to x = c will have one solution. One such equation is ...
0 = x+1
x = -1 . . . . subtract 1 from both sides
__
3. Something that reduces to x = x will have an infinite number of solutions.
One such equation is ...
x+1 = x+1
Subtracting 1 from both sides gives ...
x = x . . . . true for all values of x
First, let’s figure out the total amount of money
$15 + $4 + $3 = $22
Okay, so now we know the total amount of money spent, so we can divide
22 ÷ 4 = 5.5
5.5 = $5.50
Here are the expressions:
(15 + 4 + 3) ÷ 22 = 5.5
22 ÷ 4 = 5.5 (or 5.50)
Therefore, each friend owes $5.50
Hope this helps you

Answer:
Step-by-step explanation:
GIVEN: In a 
mile race, Janet covered the first 
miles at a constant rate. She then speed up and rode her bike the last 
miles at a rate that was 
miles per minute faster. Janet's overall time would have been minutes faster had she ridden her bike the whole race at the faster pace.
TO FIND: What was Janet's average speed (in miles per minute) for the whole race?
SOLUTION:
let the speed of Janet in first 
speed of Janet's bike in last 
total time taken by Janet,
Time taken if Janet rides whole race at faster pace 
As, Janet's overall time would have been 
faster had she ridden her bike the whole race at the faster pace.
on solving we get
Average speed 
Average speed 
Therefore average speed of Janet was
