I think it's 1/2 × length
The answer is 81. since (-3)^2 is 9. Therefore, 9x9=81.
30 mi lead
30 mph overtake speed
=1 hr
60 miles from station
Step-by-step explanation:
The coefficients of the y terms are -3 and 2. The least common multiple of 3 and 2 is 6. So multiply the first equation by 2 and the second equation by 3, so that the y terms have a coefficient of 6.
4x − 6y = 42
-18x + 6y = 21
The signs are opposite, so add the equations together.
-14x = 63
x = -9/2
it is less then 2 because d/3 is a part of fraction
