Answer:
Step-by-step explanation:
Each tick is 0.1
So for example:
2.8 would be the eighth tick between 2 and 3.
-0.9 would be between 0 and -1 and will be the ninth tick.
we know that the multiplication comes first in the family then we start from left to right
4 x 5= 20
9-20 = -11
-11 + 6 = -5
there you go!
You are correct because the elapsed time was the shortest
hope this helps!
