Basically, you need to divide these by the number of minutes it took to make them. So, for example:
Since one hour and a half equals 90 minutes, Steve baked cookies at a rate of 0.61111...... (the one keeps repeating) per minute (55 divided by 90).
Since one hour equals 60 minutes, Vondra baked cookies at a rate of 0.516666...... ( the six keeps repeating) per minute (31 divided by 60).
This means that Steve baked batches of cookies at a greater rate than Vondra.

this is the correct answer
Answer:
y = -3
Step-by-step explanation:
3x + 4y = 3
<u>2x - 4y = 12</u>
5x = 15 Add the two equation together because the y terms are
opposite each other and goes out when you add the equations
x = 5
Substitute into the first equation and solve for y when x = 5
3x + 4y = 3
3(5) + 4y = 3
15 + 4y = 3
4y = 3 - 15
4y = -12
y = -3
It is important to read the question very carefully. The trick lies in the way the question is written. Once it is understood, then the problem is easy.
Number of persons required to rearrange the floor plans in 1 hour = 42
Number of persons required to rearrange the floor plans in 9 hours = 42 * 9
= 378 hours
So it will take 378 hours by 9 persons to rearrange the floor. I hope this is the answer you were looking for and the procedure is also clear to you. Once you understand the procedure, you can attempt such problems on your own in future.
