Two machines at a factory are filling cans of soup. One machine has already filled 180 cans of soup, and fills cans at a rate of 15 per minute. The second machine has already filled 210 cans of soup, and fills cans at a rate of 12 per minute. Write an equation to show when the two machines will have filled the same number of cans of soup. Use x

12x+210=15x+180
12 x plus 210 equals 15 x plus 180

12x+180=15x+210
12 x plus 180 equals 15 x plus 210

210−12x=180−15x
210 minus 12 x equals 180 minus 15 x

12x−210=15x−180

To find out when the two machines will have filled the same number of cans of soup, we can set up the following equations based on the information provided:

  1. The first machine has filled 180 cans and fills cans at a rate of 15 cans per minute. Therefore, after \( x \) minutes, the total number of cans filled by the first machine will be: \[ 180 + 15x \]

  2. The second machine has filled 210 cans and fills cans at a rate of 12 cans per minute. Therefore, after \( x \) minutes, the total number of cans filled by the second machine will be: \[ 210 + 12x \]

To find out when the two machines have filled the same number of cans, we can set these two expressions equal to each other: \[ 180 + 15x = 210 + 12x \]

Thus, the equation that represents the situation is: \[ 180 + 15x = 210 + 12x \]

Now, let’s analyze the provided options with respect to this equation:

  • 12x + 210 = 15x + 180: This is not the correct equation derived from the conditions.
  • 12x + 180 = 15x + 210: This is not the correct equation as well.
  • 210 − 12x = 180 − 15x: This is just rearranging the terms, but it leads to the same relationship. However, it’s not in the standard form we derived.
  • 12x − 210 = 15x − 180: Also doesn't represent the situation correctly.

The correct format of the equation is as follows: \[ 180 + 15x = 210 + 12x \]

However, if we simply wanted to rearrange it, the closest version in the responses that resembles the correct form is: \[ 12x + 210 = 15x + 180 \] Therefore, the correct initial equation to state that the two machines will have filled the same number of cans of soup is: \[ \text{12x + 210 = 15x + 180} \]
