Answer:
había 18 DVDs al principio
Step-by-step explanation:
si procedemos desde el final del problema , sabemos que :
total que le quedaba después de darle los CDs a Juan - lo que fue para la hermana = lo que le sobró
x - x/3 = 6
2/3*x = 6
x= 6 * 3/2 = 9
por lo tanto tenia x=9 DVDs después de entregarle a Juan los suyos
también sabemos que
DVDs que tenia al principio - lo que fue para Juan = 9 DVDs
y - y/2 = 9
y/2 = 9
y= 18
finalmente había y= 18 DVDs al principio
You need to simplify the expression and then you will know what the y coordinates are. I’m not good at this But you just need to solve the equation to be able to get the same coordinates by themselves. It’s sorta like geometry and algebra mixed. But first simplify the equations and then that will really help you.
Have a great day!
Answer:
James is correct because 5/5 is 1 while 9/10 is 0.9. 1 is greater than 0.9 by 0.1 and that's why James is correct.
Answer:
![\frac{\sqrt[3]{19} }{\sqrt[3]{x} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%5B3%5D%7B19%7D%20%7D%7B%5Csqrt%5B3%5D%7Bx%7D%20%7D)
So A is the answer
