120+25x=45x Step 1: Simplify both sides of the equation. 25x+120=45x Step 2: Subtract 45x from both sides. 25x+120−45x=45x−45x −20x+120=0 Step 3: Subtract 120 from both sides. −20x+120−120=0−120 −20x=−120 Step 4: Divide both sides by -20. −20x −20 = −120 −20 x=6 Answer: x=6

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.

A rectangular garden has a perimeter of 172 feet. The length of the garden is 24 feet more than the width. What are the dimensio

Lilit [14]

Given width is 24 less than length.
W=L-24
Perimeter = 2(W+L)=2(L-24+L)=4L-48
But we're also given perimeter = 172'
Therefore 4L-48=172
solve for L
4L=172+48=220
L=55'
W=55-24 = 31'
Check: Perimeter = 2(W+L)=2(31+55)=2*86=172' good!

Answer: The dimensions of the garden are 31' * 55'
