Hi,


Equation:

- 7 \times  (- 5)

Multiplying two negatives equals a positive.

( - ) \times ( - ) = ( + )

Now equation looks like:

What is the substitution of -6x-8y=-20 and x+6y=-6
ale4655 [162]

Substitution doesn't work for this, but elimination does.

-6x-8y=-20 +6( x+6y=-6)

-6x-8y=-20 + 6x+36y=-36

-6x and 6x cancel each other, add -8 and 36 to get 28, and -20 and -36 to get -56.

28y=-56

divide by 28 on both sides.

Y= -2

Then substitute y into one of the equations.

x+6(-2)=-6

x-12=-6

x=6

The ordered pair is (6,-2).

In the Holiday Shop the manager wants 20% of the total inventory in the stockroom and the rest displayed on the floor. After mee
Lilit [14]

Answer:

Total inventory: $175,000

Inventory in the stockroom: $35,000.

Inventory on the selling floor: $140,000.

Step-by-step explanation:

Let x be the the total inventory.

We have been given that in the Holiday Shop the manager wants 20% of the total inventory in the stockroom. You placed $35,000 of inventory in the stockroom.

We can set an equation such that 20% of x equals $35,000.

\frac{20}{100}\cdot x=\$35,000

0.20x=\$35,000

\frac{0.20x}{0.20}=\frac{\$35,000}{0.20}

x=\$175,000

Since $35,000 of inventory in the stockroom, so we will subtract $35,000 from $175,000.

\text{Amount of the inventory on the selling floor}=\$140,000

Therefore, $140,000 of the inventory on the selling floor.
