Calculate the unit rate for Machine A and Machine B. Determine which is the greater rate. I need help on this, asap‼️

  A: 2 1/2 ft^2/h

  B: 3 1/3 ft^2/h

  B has the greater rate

Step-by-step explanation:

The rate in square feet per hour is found by dividing square feet by hours.

Machine A:

  (5/8 ft^2) ÷ (1/4 h) = (5/8)×(4/1) ft^2/h = 5/2 ft^2/h = 2 1/2 ft²/h

Machine B:

  (2/3 ft^2) ÷ (1/5 h) = (2/3)×(5/1) ft^2/h = 10/3 ft²/h = 3 1/3 ft²/h

Machine B has the greater rate.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

answer: group b.
