In order to be fulfilled m // n we must take into account the following angle:
180-105 = 75 degrees
Therefore, we match this angle to the given expression.
We have then:
3x-18 = 75
Clearing x we have:
3x = 75 + 18
x = 93/3
x = 31 degrees
Answer:
the value of x is:
A.
31
Answer:
Step 2
Step-by-step explanation:
Michelle's step in trying to solve the equation is given below:

Michelle made a mistake in Step 2.
The right hand side of Step 1: 
Rather, the correct sum is:

Answer:
4 times 7
Step-by-step explanation:
The answer is this hopefully this helped the only thing you need to do is just put the steps so just do - 12÷3 or you can ask somebody to help you to divide.
Standard form is written Ax + By = C where A, B, and C are all integers.
In other words, no fractions.
Also, the A or the coefficient of the x term must be positive.
The only thing we need to do is add 7x to both sides to get 7x + y = -1.
So 7x + y = -1 is our answer.
