Answer:the company bought 12 computers and 4 printers.

Step-by-step explanation:

Let x represent the number of computers that the company bought.

Let y represent the number of printers that the company bought.

The company buys a total of 16 machines. It means that

x + y = 16

Each computer costs $550 and each printer costs $390. If the company spends $8160 for all the computers and printers that was bought, it means that

550x + 390y = 8160 - - - - - - - - - - 1

Substituting x = 16 - y into equation 1, it becomes

550(16 - y) + 390y = 8160

8800 - 550y + 390y = 8160

- 550y + 390y = 8160 - 8800

- 160y = - 640

y = - 640/ - 160

y = 4

Substituting y = 4 into x = 16 - y, it becomes

x = 16 - 4

x = 12

Larry and Donna bought a sofa at the sale price of $1,344. The original price of the sofa was $1,920. Find the discount rate
velikii [3]

Answer:

30% discount

Step-by-step explanation:

To find the percent discount write a proportion.

\frac{1344}{1920}=\frac{x}{100}

Cross multiply numerator with denominator of each fraction to solve for x.

1344(100) = 1920(x)

134400 = 1920x

70 = x

This means you pay 70% of the price. The discount was 30%.

What are the points for -3x+6y+5=-7
Novay_Z [31]
-3x + 6y + 5 = -7
<u>                -5    -5</u>
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
 6           6
  y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
<u>     +12   +12</u>
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-3(0) + 6y = -12
0 + 6y = -12
<u>+0           +0</u>
      <u>6y</u> = <u>-12</u>
