Si camilo tiene 6 años mas que juan, juan tiene 7 años menos que andrés y andrés tiene 35 años

lidiya [134]

Answer:

Part a) Camilo is 34 years old and Juan is 28 years old

Part b) The difference between Camilo's age and Juan's age is 6 years

Part c) The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

Step-by-step explanation:

<u><em> The question in English is</em></u>

If Camilo is 6 years older than Juan, Juan is 7 years younger than Andrés and Andrés is 35 years old .

Part a) How old is Camilo and how old is Juan? raises the equation.

Part b) What's the difference between Camilo's age and Juan's age?

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Part a) How old is Camilo and how old is Juan? raises the equation.

Let

x -----> Camilo's age

y -----> Juan's age

z -----> Andres's age

we know that

$x=y+6$ -----> equation A

$y=z-7$ -----> equation B

$z=35$ -----> equation C

<em>Find the value of y</em>

substitute the value of z in the equation B

$y=35-7=28$

<em>Find the value of x</em>

substitute the value of y in the equation A

$x=28+6=34$

therefore

Camilo is 34 years old and Juan is 28 years old

Part b) What's the difference between Camilo's age and Juan's age?

Subtract Juan's age from Camilo's age

so

$x-y=34-28=6\ years$

Part c) If Andres's grandmother is 65 years old, does the sum of the ages of Camilo and Juan coincide with the age of Andres' grandmother?

Adds Camilo's age and Juan's age

$x+y=34+28=62\ years$

$62\ years\neq 65\ years$

therefore

The sum of the ages of Camilo and Juan not coincide with the age of Andres' grandmother

One solution of x^2-25=0 is 5 what is the other solution

zepelin [54]

Add 25 to both sides:

$x^2 = 25$

Square root both sides.

When you square root a perfect square, you will get a plus/minus result:

$\sqrt{25} = \pm 5$

$x = \pm 5$

$\boxed{x = -5} \land \boxed{x = 5}$

The other solution to this answer is x = -5.
