Mathematics
1 answer:

3 0

Answer: x = (-n/2)

Step-by-step explanation:

-3(x+n)=x      Problem:

-3x-n=x         Distributive property

-n=2x            Add 3x to both sides

2x=-n            Switch equation around to make it easier to look at

x= -n/2          Divide by 2 on each side

El productor del números es 28. Sabiendo que el primer número es 3 unidades menor que el segundo, calcula los dos número
Rasek [7]

Answer:

Tienes 3 números, "x", "y", "z"

=> El primero es 20 unidades menor que el segundo:

El primero es "x", y el segundo es "y", entonces:

x = y - 20

=> El tercero es igual a la suma de los dos primeros:

El tercero es "z", entonces:

z = x + y

z = (y - 20) + y

z =  2y - 20

=> Entre los tres suman 120

x + y + z = 120

y - 20 + y + 2y - 20 = 120

4y - 40 = 120

4y = 160

y = 40

Si y = 40, entonces:

x = y - 20

x = 20

Además, z = 2y - 20

z= 60

RPTA:

x=20

y=40

z=60

Mieko said that the difference between the longest rose and the shortest rose is 1 inch. Is she correct?
erastova [34]

Answer:

Mieko is correct

Step-by-step explanation:

Given

See attachment for complete question

Required

The length difference

Lengths with dot(s) means, there is at least 1 rose flower of that length.

So, from the attachment, we have:

Longest = 14.0

Shortest = 13.0

The difference (d) is:

d = Longest - Shortest

This gives:

d = 14.0 - 13.0

d = 1\ in

<em>Hence, Mieko is correct</em>
