Answer:
60 miles
Step-by-step explanation:
If it takes 15 hours to travel 900 miles then it gives you the fraction 15/900 where the numerator(top number) is 15 and denominator(bottom number) is 900.
Then to simplify it: since 15 is a common factor of itself(15) and 900, 15/15 = 1(1 hour) and 900/15 = 60(60 miles).
Y=mx+b, m= slope, b= y intercept, plug in. Y=3x+5
3.0 x 10^8 km/s is how far light travels.
3.0 x 10^8 km/s x 60s is how far light travels in a minute
3.0 x 10^8 x 60 x 5 is how far light travels in 5 minutes, and you should get D as your answer.
<em>Answer: x = 5</em>
<em>Step-by-step explanation:</em>
<em>multiply the outside number to both numbers in parenthesis</em>
<em>3x-15 divide</em>
<em> find out how many time 3 goes into 15 and divide </em>
<em>three divided by fifteen equals five</em>
