Answer:

distance = rate x time

3 and 1/5 = 3.2 and 3 and 3/5 = 3.6

distance = 3.2 x 4.5 = 14.4

14.4 = 3.6 x T

T = 14.4 / 3.6 = 4 <--- Pedro's time

What is -3 - 9n= 42 I can’t be negative
maw [93]

If you were to correctly simplify this equation, the answer would be a negative.

The answer is: n = -5

Here's how I got my answer:

Step 1: Add 3 to both sides. Which leaves us with -9n=42+3

Step 2: Simplify 42+3 to 45. Which leaves us with -9n = 45

Step 3: Divide both sides by -9. Which leaves us with n = -45/9

Step 4: Simplify -45/9, to get your answer, n = -5.
