Mr Nersin likes to ride his bike. He rode for 1/2 hour. After a short rest, he rode 1/10 hour more. He traveled 4 miles in all.
vodomira [7]
The distance traveled by Mr.Nersin = 4 miles
The time for which Mr.Nersin rode first = 1/2 hour
The time for which Mr.Nersin rode after a short rest = 1/10 hour
Then
The total time for which Mr.Nersin rode = (1/2) + (1/10) hour
                                                                = (5 + 1)/10 hour
                                                                = 6/10 hour
                                                                = 3/5 hour
So
Average speed of Mr. Nersin = Distance traveled / Time taken
                                                = 4/(3/5) miles/hour
                                                = (4 * 5)/3 miles/hour
                                               = 20/3 miles/hour
                                                = 6 2/3 miles/hour
                                                = 6.67 miles per hour
So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.

3x-6y=6 in function notation
JulijaS [17]
Subtract 3x from both sides:

-6y = -3x + 6

divide both sides by -6 to get y by itself:

y = 1/2x - 1

function notation is rewriting y as a function:

f(x) = 1/2x -1

Can someone help it’s due in 40mins!!
Lorico [155]

Answer:

Step-by-step explanation:

\frac{8}{32}  =  \frac{4}{16}  =  \frac{2}{8}  =  \frac{1}{4}

\frac{27}{54}  =  \frac{9 }{18}  =  \frac{3}{6}  =  \frac{1}{2}

\frac{36}{24}  =  \frac{18}{12}  =  \frac{9}{6}  =  \frac{3}{2}

\frac{30}{60}  =  \frac{15}{30}  =  \frac{5}{10}  =  \frac{1}{2}
