Answer:
F
Step-by-step explanation:
Multiply -3 by 6.5 and you'll get your answer :)
I hope I helped!
-10x-10 = -3x+4
+3x +3x
————————
-7x-10 = 4
+10 +10
————————
-7x = 14
then divide -7 on both side of the equal sign
you’ll get x=-2
then plug in -2 as x into one of the equations ( it doesn’t matter which one)
y= -10(-2)-10 = 20-10= 10
so y=10
Car A travels 180miles in 7 hours
Car A travels 25.7 miles an hour because 180/7 = 25.7
Car B travels 350 miles in 4 hours
Car B travels 87.5 miles an hour because 350/4= 87.5
Car C travels 584 miles in 15 hours
Car C travels 38.9 miles an hour because 584/9 = 38.9
Car B has the fastest average speed
