Answer:
(A) x=40
Step-by-step explanation:
Given: It is given that m is parallel to n.
To find: The value of x.
Proof: It is given that m is parallel to n, from the figure it can be seen that 105° and (3x-15)° forms alternate exterior angles which are equal in measure because m is parallel to n.
Thus, 
⇒
⇒
⇒
⇒
Thus, the value of x is 40, hence option A is correct.
Answer:
7/9 and 6
Step-by-step explanation:
Coefficients are intergers that are parted with a variable.
7/9 and 6 are the coefficients
I believe x would equal to 30.
Since 6 * 3 =18, 10 * 3 = 30.
What you do to one side, you must do to the other.
Hope I helped!
