Answer:
9u
Step-by-step explanation:
18u³ / 9u = 2u²
45u²/9u = 5u
27u / 9u = 3
<h3>Given :-</h3>
- Pranav ran 20.3 km more than Branda
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
To find :
- No. of kilometers did Brenda run.
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
<h3>Let :</h3>
- No. of kilometers ran by Brenda be x.

<h3>Solution:</h3>

Equation formed:-
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
Total distance covered by Pravan = More distance covered by Pravan + distance covered by Brenda.
Therefore:-

![\leadsto \sf38.6 = 20.3 + x](https://tex.z-dn.net/?f=%20%5Cleadsto%20%5Csf38.6%20%3D%2020.3%20%2B%20x)
Write the equation
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
![\leadsto \sf38.6 - 20.3 =x](https://tex.z-dn.net/?f=%20%5Cleadsto%20%5Csf38.6%20-%2020.3%20%3Dx)
When we transfer 20.3 to left side the positive sign (+) will change into negative sign (–)
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
![\leadsto \sf x = 38.6 - 20.3](https://tex.z-dn.net/?f=%20%5Cleadsto%20%5Csf%20x%20%3D%2038.6%20-%2020.3)
Arrange the equation because x is always represented at left side.
![\\ \\](https://tex.z-dn.net/?f=%20%5C%5C%20%20%5C%5C%20)
![\leadsto \boxed {\pmb{\sf x = 18.3}}\star](https://tex.z-dn.net/?f=%20%5Cleadsto%20%5Cboxed%20%7B%5Cpmb%7B%5Csf%20x%20%3D%2018.3%7D%7D%5Cstar)
After subtracting 38.6 with 20.3 we will get result as 18.3 .

32.75 + 39.88 = 72.63
72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.
114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
If you were to have (3,2) and find the reflection of the y axis, it would turn y into a negative, making it (3,-2).
