Answer:

The correct answer would be the third one; 4y-6y

Step-by-step explanation:

The first answer, if simplified, the answer would be 10y. Which isn't the answer you are looking for.

The second answer, also has the answer of 10y, which means that isn't the one.

The third answer, when simplified, has the answer of -2y. Which, of course, would be your answer.

The fourth answer, would be -10y.

Therefor, the correct answer would be the third one.

Hope this helps!

Answer: 33 minutes

Step-by-step explanation:

Hi to answer this question we have to write a proportion

Speed rate = 88 step per minute

Time = 90 minutes

So, the proportion is 88 step/min / 90 minutes

For 33 steps per minutes = 33 / x minutes

88/90 = 33/x

solving for x:

x= 33/ (88/90)

x = 33.75 = 33 minutes.
