Put the number as x and translate the English into math;

Then solve for x
8x+1=36
8x=35
x=4.375 or 4 3/8

Justo ayer fue el cumpleaños de Mauricio. Si a la edad e Mauricio, le sumo 13, al resultado le resto 10, luego al nuevo resultad

bezimeni [28]

Answer:

Mauricio nació en el año 2000.

Step-by-step explanation:

Supóngase que el cumpleaños se celebra en el año 2020, si $x$ es la edad actual de Mauricio, entonces la expresión matemática que traduce el enunciado del problema es:

$\frac{(x+13)-10}{23} +20 = 21$

Ahora, se desarrolla y se simplifica la ecuación:

$\frac{x+3}{23}+20 = 21$

$\frac{x+3}{23} = 1$

Se despeja $x$ :

$x +3 = 23$

$x = 20$

Mauricio tiene 20 años.

Ahora, el año de nacimiento de Mauricio es la sustracción de la edad de Mauricio del año actual:

$y = 2020-20$

$y = 2000$

Mauricio nació en el año 2000.

Michael Jordan is 6'6'' tall and could jump 4 feet of vertical distance off the ground.A basketball net's rim is 3.9 meters off

Vaselesa [24]

No. 6+4=10. Michael Jordan's head reaches 10'6" above the ground. A meter is slightly more than 3 feet, so 3.9 meters is more than 11'8".

MJ's head would not reach the rim by more than a foot.
