If lisa can run a mile in 7 minutes. At that rate of speed, how long would it take her to run 2 kilometers?
murzikaleks [220]

Answer:

8.75

Step-by-step explanation:

1 mile = 1.6 km

So, every 7 minutes, 1.6 km is ran.

Divide 1.6 by 2 to figure out how much more she is running.

1.6 / 2 = 0.8

Divide the known pace by the extra distance to figure out the time

7 min / 0.8 km = 8.75 min

8x+5y=35 solve for y no work needed but you can show me the work if you want i will still look at it thank you in advance
solong [7]

Answer:

y=7-(8/5)x

Step-by-step explanation:

To solve for y we need to get Y on one side of the equation all by itself.  To start we can move the 8x to the side with the 35 by subtracting 8x on both sides which gets us to 5y=35-8x then we just need to get the 5 detached from the y and we will have solved for Y.  To do this we can divide by 5 on both sides to cancel out the 5 with the Y which leaves us with y=7-(8/5)x

I hope this helps and please don't hesitate to ask if there is anything still unclear!
