2X+15= -3x how do you work this equation

Sphinxa [80]

Answer: $x=-3$

<u>Add 3x to both sides</u>

<u></u> $2x+15+3x=-3x+3x\\5x+15=0$ <u></u>

<u></u>

<u>Subtract 15 from both sides</u>

<u></u> $5x+15-15=0-15\\5x=-15$ <u></u>

<u></u>

<u>Divide both sides by 5</u>

<u></u> $5x/5=-15/5\\x=-3$ <u></u>

What is the average speed (miles/hour) for an object going 1500 feet in 1 minute. Round answer to two decimal places.

svetlana [45]

there are 3600 seconds per hour

5280 feet per mile

1 foot per second = 3600/5280 = 0.681818 Miles per Hour

60 seconds per minute

so 1500/60 = 25 feet per second

25 x 0.681818 = 17.05 miles per hour
