When you add a negative, it’s same as subtracting therefore it’s -4-1
The answer is -5
Answer:
It is the forth one
Step-by-step explanation:
to long to explain
Given :
A squirrel climbs up a tree. She starts at 0.5 feet up the tree, then climbs at a steady pace for 7.5 seconds.
She ends 4 feet up the tree.
Solution :
Now, distance covered is :
d = 4 - 0.5 = 3.5 feet.
Time taken, t = 7.5 seconds.
Distance climbed per second is :

Therefore, distance climber per second is 0.467 feet.
Hence, this is the required solution.
A/3=7/10
21=10a
a=2.1
100a=100*2.1=210
The answer of this would be D 38.5
