Hello!
We are told that n and m are parallel.
The angle that measures 105 degrees is supplementary with the alternate interior angle of the angle which measures (3x - 18) degrees. Supplementary angles add to equal 180 degrees, so we can make an equation by first finding the measure of the alternate interior angle.
180 - 105 = 75
The alternate interior angle measures 75 degrees, so we can set that equal to 3x - 18 to solve for x since alternate interior angles are congruent.
75 = 3x - 18
93 = 3x
31 = x
Answer:
x = 31
Variable: a symbol for a number you don’t know yet
inequality: 60=22+8x
Answer:
I think it could be first is 5 second 12 and 13 last or in another order
Answer:
ok im not sure this is the right answer to your specific question, because i dont understand the wording to well, but here...
for 1/7 and 1/2 it would be 2/7 and 1 (whole)
for 1 and 1/7 it would be 2(whole) and 2/7
for 1 and 2/7 it would be 2(whole) and 4/7
for 4/9 it would be 8/9 and x
and for 2/9 it would be 4/9 and x
sorry if thats not the question :)
EDIT: its the second one because
2*1/7= 2/7
and 1/2*2=1
