Actually Welcome to the concept of Linear Equations

After solving all the Equations we get as,

I have solved the Above four equations, 1.) and no. 2.) is the horizontally adjacent to no. 1.) , hope you get it.

1.) 2x = 14 ===> x = 14/2 ===> x = 7

2.) X - 5 = 20 , X = 20+5 ===> X = 25

3.) 4 + (x +6) = 10 ==> 10 + x = 10 ==> x = 0

4.) 7(x-12) = 21 ===> x-12 = 3 ===> x = 15

9.) -8x -8 = 160 ===> -8x = 168 ===> x = -21

10.) -8k -5 = -133 ==> -8k = -128 ==> K = 16

11.) 0 = -12n+12 ===> -12n=-12 hence, n = 1

12.) -7+n/2=4 ==> -7-4 = -n/2 ==> -11 =-n/2 ==> -n=-22 ==> n = 22

13.) 7*3= n-7 ==> 21=n-7 ==> n = 28

14.) 4+m/10 = 2 ==> 4+m = 20 ==> m = 20-4 ==> m=16

The amount of $180.00 is what percent greater than $135.00
olga nikolaevna [1]
Percent change = ((new value) - (old value))/(old value) × 100%
  = (180 -135)/135 × 100%
  = 33 1/3%

180 is about 33% greater than 135.

Problemas de razonamiento división de números decimales. Ayer Susana se fue de viaje a visitar a unos familiares. Recorrió 135,7
schepotkina [342]

Usando las relaciones entre velocidad, distancia y tiempo, se encuentra que ella condujo a una velocidad media de 90,5 km/h.

--------------------------

La <u>velocidad </u><u>es la distancia dividida por el tiempo</u>, por lo que:

v = \frac{d}{t}

  • Total de 135,75 km, o sea, d = 135,75
  • Llego en 1,5 horas, o sea, t = 1,5

La velocidad es:

v = \frac{d}{t} = \frac{135,75}{1,5}

División de decimales, o sea, seguimos multiplicando los números por 10 hasta que ninguno sea decimal:

v = \frac{135,75}{1,5} = \frac{1357,5}{15} = \frac{13575}{150} = 90,5

Ella condujo a una velocidad media de 90,5 km/h.
