Expand
-5m + 45 = 27 - 7m
Subtract 27 from both sides
-5m + 45 - 27 = -7m
Simplify -5m + 45 - 27 to -5m + 18
-5m + 18 = -7m
Add 5m to both sides
18 = -7m + 5m
Simplify -7m + 5m to -2m
18 = -2m
Divide both sides by -2
-18/2 = m
Simplify 18/2 to 9
-9 = m
Switch sides
<u>m = -9</u>
Answer:
The difference of fifty-four and seven times a number is written as 54 - 7x.
Step-by-step explanation:
Given: expression “the difference of fifty-four and seven times a number”
We have to write the given algebraic expression represents “the difference of fifty-four and seven times a number”
Consider the given algebraic expression represents “the difference of fifty-four and seven times a number”
Let the number be x
Then, seven times a number is 7x
And the difference of fifty-four and seven times a number is written as 54 - 7x.
Thus, The difference of fifty-four and seven times a number is written as 54 - 7x.
A reasonable price for X would be $ 2.
Since a class of 30 students visits an art museum and a special exhibit while there, and the prices were as follows:
- Child (under 5) Free Free
- Student $ 8 $ x
- Regular $ 12 $ 4
- Senior $ 10 $ 3
To estimate a reasonable value for x, the following logical reasoning must be made:
- Regular 12 Senior 10 Student 8 = -2
- Regular 4 Senior 3 = -1
Therefore, a reasonable price for X would be $ 2.

The answer to your question is: the second option
Step-by-step explanation:
The slope- y-intercept is y = mx + b
b = y-intercept
In this problem b changes from + 8 to -3, then the difference is 11 units down
