Si Ana es 12 años menor que Eva y dentro de 7 años la edad de Eva es el doble que la edad de Ana, ¿qué edad tiene Eva?

Eva is 17 years old

Step-by-step explanation:

First, we know that Ana is 12 years younger than Eva.

This means that, if Eva is x years, then Ana would be (x-12) years old

Now, within 7 years Eva’s age is twice that of Ana

Mathematically, that means when we add 7 years to each of their ages, we have the result as in the statement above.

Thus;

x + 7 = 2(x -12+ 7)

x + 7 = 2(x-5)

x + 7 = 2x -10

2x-x= 10 + 7

x = 17 years

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

you answer is a
