Answer:
x=.4
Step-by-step explanation:
3y - ( 4y + 19 ) = - 13 ;
3y - 4y - 19 = - 13 ;
- y - 19 = - 13 ;
-y = 19 - 13 ;
-y = 6 ;
y = - 6 ;
Then, x = 4 * ( - 6 ) + 19 ;
x = - 24 + 19 ;
x = - 5 ;
The solution of the system is x = - 5 and y = - 6 ;

Answer:
San Francisco with average speed of 639 km/hour
Step-by-step explanation:
Phoenix 3 1,689
Minot 2 913
San Francisco 4 2,556
Phoenix average speed = distance travelled / time taken
= 1,689 km /3 hours
= 563 km/hour
Minot average speed = distance travelled / time taken
= 913 km / 2 hours
= 456.5 km/hour
San Francisco average speed = distance travelled / time taken
= 2,556 km / 4 hours
= 639 km/hour
The fastest average speed flight is San Francisco with an average speed of 639 km/hour
