If it's possible to tell, decide if a and b are positive or negative: a-3>b-3 and b>4

Answer:

a and b are positive

Step-by-step explanation:

We are given that

$a-3>b-3$

$b>4$

We have to find that a and b are positive or negative.

We have

$b>4$

It means b is positive and greater than 4.

$a-3>b-3$

Adding 3 on both sides

$a-3+3>b-3+3$

$a>b>4$

$\implies a>4$

Hence, a is positive and greater than 4.

Therefore, a and b are positive

Answer:

Adam

Step-by-step explanation:

Speed is calculated with the formula distance over time.

Convert all measurements to the same unit: ft/s.

Speed of Frank:

d/t

=11/s

Speed of Emily:

d/t

=86/10

=8.6/s

Speed of Adam:

There are 5280 feet in a mile.

d/t

=5280/388

=13.6/s

Speed of Noah:

There are 60 seconds in a minute.

d/t

=600/60

=10/s

Adam runs the fastest because 13.6 > 11 > 10 > 8.6.
