Answer:
-3.4
Step-by-step explanation:
negative numbers are reverse counting on the line graph.
-3 1/2 is -3.5
-3.4 VS. -3.5
since it is reverse, -3.4 is greater
So car A travels Distance = 60 km/hr*(1+x)
Car B travels Distance = 75 km/hr(x)
Where x is the time in hours.
Those two equations are equal when on overtakes the other
so:
60 +60x = 75x
60=15x
x=4, but my expression is written to count from when car B commenced travel. So total time is 5 hours from the car A setting off.
Answer:Perimeter=5*2+2*(x-2)
Step-by-step explanation:
Because perimeter =2*length+2*width
72 + 74 is 146.
The angle sum of a triangle is 180.
180 - 146 is 34.
