Answer:x in (-oo:+oo)
(7/2)*x+(1/2)*x = (5/2)*x+101/2 // - (5/2)*x+101/2
(7/2)*x+(1/2)*x-((5/2)*x)-(101/2) = 0
(7/2)*x+(1/2)*x+(-5/2)*x-101/2 = 0
3/2*x-101/2 = 0 // + 101/2
3/2*x = 101/2 // : 3/2
x = 101/2/3/2
x = 101/3
x = 101/3

Depending on the size of the track but from what I know, they are normally 400 meters for 1 lap. All you need to do is 5000 divided by 400 which is 12.5 so 5000 meters is 12 and a half laps around the track.
Answer:
<u>1.75 x 10^3</u>
Step-by-step explanation:
This is quite a simple question really, we just have to remember one thing, the exponent laws. When both exponents have the same base and are getting divided by each other, you subtract the exponents.
So in this case we have 10^8 on top divided by the 10^5 on the bottom, so now you just subtract the 5 from 8 and you get 3 as your final exponent. So your power would just be 10^3.
The final step is just dividing 7 by 4 which is 1.75
Combine the power and 1.75 together to get the correct notation
<u>1.75 x 10^3 </u>
