I decided to do mental math and figured out it was -12. but you can cross multiply since both answers have to equal one another. you will still get the answer.
C. the time is between 9:00 AM and 5:00 PM, then many people are likely at work and unable to buy stamps or mail pachages
*they go to work at 8 or 9 in the morning and the usaul time to get off work is 5... but you font have to agree with me yanno*
Answer:
<1 and <3
<1 and <4
<2 and <1
<2 and <3
Step-by-step explanation:
Find the diagram attached
First know that supplementary angles are angles that sums up to 180degrees. Since the sum of angles on a straight line is also 180degrees, then the pair of supplementary angles must lie on the same straight line.
According to the given diagram, the following angles are supplementary since they lie on the same straight line;
<1 and <3
<1 and <4
<2 and <1
<2 and <3
The sum of all the pair of angles is 180 degrees
3·m - 2/3 - 2·m + 1/4 = 2/12
m - 2/3 + 1/4 = 2/12
m = 2/12 - 3/12 + 8/12
m = 7/12
