Two-thirds a numer plus 4 is 7

1 answer:

8 0

Since we don't know the number yet, we'll give it a name.
That will make it easier to work with.
It can have any name. I've decided to call it ' Z '.

-- The number    Z

-- Two thirds of the number       2/3 Z

-- Two thirds of the number plus 4    2/3 Z + 4

The question says that makes 7 : 2/3 Z + 4 = 7

Subtract 4 from each side:    2/3 Z = 3

Multiply each side by 3 : 2 Z = 9

Divide each side by 2 :    Z     = 4.5

How do I write an inequality for 6x+8>2

Hatshy [7]

Answer:

The inequality is $x>-1$

Step-by-step explanation:

Given:

The inequality to solve is given as:

$6x+8>2$

Now, in order to solve it for 'x', we need to isolate 'x' on one side of the inequality.

<em>Adding -8 on both sides, we get:</em>

$6x+8-8>2-8\\\\6x>-6$

<em>Dividing both sides by 6, we get:</em>

$\frac{6x}{6}>\frac{-6}{6}\\\\x>-1$

Therefore, the inequality for 'x' is given as:

$x>-1$

So, 'x' include all the values that are greater than -1.

Answer:

The number of units sold increased by $\mathbf{11.2\%}$

Step-by-step explanation:

Vacuum dealer sold units in 2011 = 420

Vacuum dealer sold units in 2012 = 467

We need to find percent increase or decrease

Since, In 2012 units sold are greater than 2011, so there will be percent increase.

The formula used is: $Percent\:Increase=\frac{New\:Value-Original\:Value}{Original\:Value}\times 100$

We have New Value (Units sold in 2012) = 467

Original Value (Units sold in 2011) = 420

Percent increase is:

$Percent\:Increase=\frac{New\:Value-Original\:Value}{Original\:Value}\times 100\\Percent\:Increase=\frac{467-420}{420}\times 100\\Percent\:Increase=\frac{47}{420}\times 100\\Percent\:Increase=11.2\%$

So, The number of units sold increased by $\mathbf{11.2\%}$
