X=11, set 10x+5x+15=180
15x+15=180, subtract 15 from 180= 165, then divide 165 by 15
Answer:
suman is 15 and renu is 30 anita is 24
Step-by-step explanation:
15+30+24+69
Easy peasy
just use PEMDAS and some exonential laws



also another is
![x^{\frac{m}{n}}=\sqrt[n]{x^{m}}](https://tex.z-dn.net/?f=%20x%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%5E%7Bm%7D%7D%20)
so
![[3(2a)^{\frac{3}{2}}]^{2}](https://tex.z-dn.net/?f=%20%5B3%282a%29%5E%7B%5Cfrac%7B3%7D%7B2%7D%7D%5D%5E%7B2%7D%20)

<span>As far as i know it is related to Gauss.
Write the sequences forward and backward first.
1 +2 +3 +.....+1002
1002+1001+1000+.....+1
--------------------------------------... Adding them
1003+1003+......(1002 times)
=1002x1003
But this contains the series twice.
So, the sum is = 1002x1003/2=501x1003=502503. answer</span>
Respuesta:
Sí, tienen el mismo descuento del 40%
Explicación paso a paso:
Dado :
PANTALÓN :
Precio inicial = 150
Precio con descuento = 90
Porcentaje de descuento en el precio:
(150 - 90) / 150 * 100%
60/150 * 100%
0,4 * 100
= 40%
CAMISA:
Precio inicial = 40
Precio con descuento = 24
Porcentaje de descuento en el precio:
(40-24) / 150 * 100%
16/40 * 100%
0,4 * 100
= 40%
Sí, tienen el mismo descuento del 40%
