Answer:

$x=-2$

Step-by-step explanation:

$-5 + 12x = 18x + 7$

Add 5 to both sides:

$-5+12x+5=18x+7+5$

$12x=18x+12$

Subtract 18x from both sides:

$12x-18x=18x+12-18x$

$-6x=12$

Divide both sides by -6:

$\frac{-6x}{-6}=\frac{12}{-6}$

$x=-2$

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.

Please help me- thank you

Answer:
(2^2)(z^7)

Explanation:
The quotient rule states that if two powers have the same base and are on opposite places of a fraction (one is on the numerator, the other on the denominator), you subtract the exponents.

First looking at the powers with the bases of 2, 2^8 is the numerator and 2^6 is the denominator. When we subtract 8-6 we get 2, so 2^8/2^6 would simplify to 2^2.

Then, we look at the powers with the base of z. z^10 is the numerator and z^3 is the denominator. When we subtract 10-3 we get 7, so z^10/z^3 would simplify to z^7.

I hope this helps! Please comment if you have any questions:)

What type of chart or graph would you use to compare individual family members’ daily water usage?

Ahat [919]

Answer:

Use a line graph with multiple lines.

Step-by-step explanation:

Since line graphs show data over time, and you have multiple people, this is a perfect choice. Put the days or however amount of time on the x axis, and the gallons or a different water amount on the y-axis. Color-code the lines to each family member.
