Theodore says 7×600 is greater than 6×7000. cristal says 7×600 is less than 6×7,000.​
noname [10]

Answer:

Cristal is correct because 7 x 600 is less than 6 x 7,000.

Step-by-step explanation:

Because they are just switching the numbers 7 and 6 and 7 x 6 = 6 x 7, you have to look at the number of zeros. As you can see, 7,000 has 1 more zero than 600, so Cristal is correct. Just like I said 7 x 6 and 6 x 7 is interchangeable, so is 7 x 600 and 6 x 700, they both equal 4,200. However, 6 x 7,000 is 42,000.

Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe and please mark brainliest! :)

<h2><u>Functions</u></h2>

The relationship between both prices is determined by function (R - 1 = B + 2).

It is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).

Given that brown rice cost $ 2 per pound, and beans cost $ 1 per pound, and Alexa has $ 10 to spend on these items to make a meal for a dinner she is attending, to determine if it is the amount of rice purchased a function of the amount of beans purchased, the following calculation must be performed:

  • 2 x 5 + 0 = 10
  • 2 x 4 + 2 = 10
  • 2 x 3 + 4 = 10
  • 2 x 2 + 6 = 10
  • 2 x 1 + 8 = 10
  • 2 x 0 + 10 = 10

Therefore, it is clear that for each pound less of brown rice there will be 2 more pounds of beans, with which there is a direct relationship between both quantities, which is determined through a function (R - 1 = B + 2).
