We know these two angles make a right angle.

Therefore, we can right the equation:
90 = 22 + 4x

We can then solve this algebraically...
90 = 22 + 4x
[Subtract 22 from both sides]
68 = 4x
[Divide both sides by four]
17 = x

Therefore, x = 17

90-22=68 then you divide that by 4 and your answer will be 17

La edad de juan es un año menos que la tercera parte de la edad de la madre. si dentro de 5 años, la edad de la madre sera 10 añ
koban [17]

Usando un sistema de ecuaciones, se encuentra que Juan tiene 12 años e su madre tiene 39 años.

<h3>¿Qué es un sistema de ecuaciones?</h3>

Un sistema de ecuaciones es cuando dos o más variables están relacionadas y las ecuaciones se construyen para encontrar los valores de cada variable.

En este problema, las variables son:

  • Variable x: Edad de Juan.
  • Variable y: Edad de su madre.

La edad de juan es un año menos que la tercera parte de la edad de la madre, por eso:

x = \frac{y}{3} - 1

Dentro de 5 años, la edad de la madre sera 10 años mas que el doble de juan, por eso:

y + 5 = 2(x + 5) + 10

y + 5 = 2x + 20

Como x = \frac{y}{3} - 1:

y + 5 = \frac{2y}{3} + 18

3y + 15 = 2y + 54

y = 39

x = \frac{y}{3} - 1 = \frac{39}{3} - 1 = 13 - 1 = 12

Juan tiene 12 años e su madre tiene 39 años.

A bag contains 42 red, 45
AlexFokin [52]

Answer:

31

Step-by-step explanation:

First of,

or, in probability is subtraction and not means you shouldn't use green (therefore leaving you with yellow and red)

Red = 42

Yellow = 20

P(Yellow or Not Green) = \frac{R+Y}{2}

⁘ \frac{42+20}{2} = \frac{62}{2}

Hence, 31
