Gnom [1K]

Answer:

He have at the beginning inventory of 4,000.

Step-by-step explanation:

Given:

Last month robert sold three quarters of his inventory and then bought 3,000 in new inventory.

If now he has 6,000 in inventory.

Now. to find inventory he have at the beginning of last month.

Let the inventory at the beginning of last month be $x.$

The inventory he sold last month:

$\frac{3}{4}\ of\ x$

$=\frac{3}{4} \times x$

$=\frac{3x}{4}$

Then, he bought inventory 3,000 in new inventory.

Now, he has 6,000 in inventory.

So, we set an equation to solve it:

$\frac{3x}{4} +3000=6000$

Subtracting both sides by 3000 we get:

$\frac{3x}{4} =3000$

Multiplying both sides by 4 we get:

$3x=12000$

Dividing both sides by 3 we get:

$x=4000.$

Therefore, he have at the beginning inventory of 4,000.

Solve the inequality for v. -24 < 6 - 5v Simplify your answer as much as possible

user100 [1]

Answer: 3.6 > v

Step-by-step explanation:

-24 < 6 - 5v

First subtract 5 from both sides

-18 < -5v

now divide both sides by -5v

3.6 < v

Now switch the signs because you divided (you also switch signs if you multiply both sides fyi)

3.6 > v

Answer:

$x=25$

Step-by-step explanation:

Set an equation:

$x + x -5 = 45$

Combine like terms:

$2x - 5 = 45$

Add 5 to both sides:

$2x = 50$

Divide both sides by 2:

$\frac{2x}{2} = \frac{50}{2}$

$x = 25$
