Answer:
He can run 20 ft in 15 seconds
Step-by-step explanation:
we need to change yards to ft
3ft = 1yd
100 yds * 3ft/1yd = 300 ft
distance = rate * time
300 ft = rate * 15 seconds
divide by 15 seconds on both sides
300 ft/15 seconds = rate
20 ft/sec
He can run 20 ft in 15 seconds
Make x=0 in the second equation, giving you y=-3. If you plug that in to the top equation you would get x-3(-3)=-19, x+9=-19,x=-28.

The answer is x=-21 im absolutly positive
Hello.
Numbers with | | around them are the absolute value, meaning it is always positive.
|-1.43| and |-1.21| become 1.43 and 1.21
The equation is now 1.43 - 7.1 + 1.21
Solve.
1.43 - 7.1 + 1.21
-5.67 + 1.21
-4.46
-4.46 is the final answer.
