Answer:
x = 19
Step-by-step explanation:
123°+3x = 180°
3x = 180°-123°
3x = 57
x = 57/3
x = 19
The reason why we use 123° + 3x = 180° because both are adjacent angles. Adjacent angles add up to 180°

Answer:
Step-by-step explanation:
The equation that will model this situation will be of the form
where is the time in hours john has traveled since the gas station, and is the distance.
Now we know that John has already traveled 20 miles when he is at the gas station, this means at , ; or
Thus we have
.
Now we need to figure out
When John reaches home 2 hours later he notes that he has traveled 30 miles, which means he has traveled 30 - 20 = 10 miles; thus we have
Now we have the full equation:
