Solve for x: −4|x + 5| = −16
Annette [7]
-4 | x + 5 | = -16...divide both sides by -4, eliminating it on the left side
| x + 5 | = -16/-4
| x + 5 | = 4

x + 5 = 4           -(x + 5) = 4
x = 4 - 5            -x - 5 = 4
x = -1                 -x = 4 + 5
                          -x = 9
                           x = -9

solutions : x = -1 , x = -9

Son proporciones.<br> cual es el resultado de :x/2,5=y/5 si x+y=6
omeli [17]

Respuesta: x/2,5=y/5=4/5=0,8


x/2,5=y/5

Multiplicando ambos lados de la ecuación por 5:

5(x/2,5)=5(y/5)→2x=y→y=2x

Sustituyendo y por 2x en la ecuación x+y=6:

x+2x=6

Resolviendo para x: Sumando términos semejantes:

3x=6

Dividiendo ambos lados de la ecuación entre 3:

3x/3=6/3

x=2

Sustituyendo x por 2 en la formula y=2x

y=2(2)→y=4

Determinando la proporción:

x/2,5. Sustituyendo x por 2:

2/2,5

Multiplicando numerador y denominador por 2:

2*2/(2,5*2)=4/5

La proporción es 4/5=0,8

Si lo hacemos con y:

y/5

Reemplazando y por 4:

4/5=0,8 (la misma proporción)
