Answer:
x=−4
Step-by-step explanation:
Rearrange terms
20−2=−7
−2+20=−7
Subtract 20 from both sides of the equation
−2+20=−7
−2+20−20=−7−20
Subtract the numbers
−2=−7−20
Add 7 to both sides of the equation
−2=−7−20
−2+7=−7−20+7
Simplify
5=−20
Divide both sides of the equation by the same term
5x=-20
5x/5=-20/5
Simplify
x=-4
You find the pattern and keep doing it.
The correct answer of the given question above would be option d and option b. The conversion factors that should be used to convert 4km/min are 60 minutes is to 1 hour and 1 kilometer is to 1000 meters. Therefore, in 4km/min, there are 4000m in every 0.0167 min.
