19) because 1/2 an hour is 8 miles, 1 hour will take 16 miles , multiply 8 by 2 because I️t gave half an hour so multiplying by 2 will give an hour (2 half’s make a whole)

20) 2 1/2 multiplied by 4 is 10, so his jog will be 10 minutes longer

21) 4,500 was what he earned and 4,900 was what he lost (“expenses”) so he lost $400:
$4,500 - $4,900= -$400
He lost money because the answer is negative

Someone please help me with this question
Sauron [17]

Answer:

3

Step-by-step explanation:

The 0th power is attached to the b, so this means that b = 1. Multiply 9 and (1) together to get 9.

Now you can subtract 9 from 12 to get 3 as your final answer.
