How do you solve 3y=4x-27

y=-4/3+9 if you need it in slope intercept form

To figure this question out, we simply must do a little division and multiplication. I see that you've given the conversion rate of miles to meters, so I assume that the car travels 100 METERS per 5 seconds, rather than 100 miles per 5 seconds. Now, we can take the 100 meters and divide by 5 to figure out how many meters is traveled per second. 100 divided by 5 is obviously 20, very easy division. Now, here comes the large numbers. We know that 3600 seconds is in an hour, so we can do 20 meters times 3600 seconds to find out how many meters is traveled per hour.

20 * 3600 = 72,000

Now that we have that number, we can convert the amount of meters traveled per hour (72,000) into miles. As listed above, 1 mile equals 1609 meters. So to convert, all we have to do is 72,000 divided by 1609.

72,000 / 1609 = 44.7

So there we have it, the answer is:

D. 44.7 miles per hour

I hope this cleared up any confusion you may have been having.
