Can someone help me solve this?
Dovator [93]

Answer:

5 felt pads.

7 cards.

Step-by-step explanation:

Remark

  • The total number of items is 12
  • So let the felt sheets be x
  • Let the cards = y

Equations and Solution

x + y = 12

Now the price is 7.75 that she has to pay for the 12 items. She wants to come back with 0 dollars.

0.5x + 0.75y = 7.75             Multiply this equation by 2

x + 1.5y = 15.50                    write the first equation underneath and subtract.

<u>x +    y =   12</u>

      .5y =  3                          Divide by 0.5

y = 3/0.5

y = 7

So she can get 7 cards.

x + y = 12

x + 7 = 12

x = 12 - 7

x = 5

So she can buy 5 felt pads.

The Ribys spent 5625 for 4.5 acres of land Find the price per acre
Margarita [4]
We can find the price per arc by dividing the total price by the amount of arc.
so in this case
5625 is the total money spent
and 4.5 is what they get when spending that amount of money
5625 / 4.5
= 1250
The price per arc is $1250
therefore, the answer is $1250.
