Answer:

The answer is 66 ways .

The class needed to collect 20.5 pounds of cans for recycling over the next 5 months. the students plan to collect 3.75 pounds e
Anestetic [448]
To solve this problem, start by finding how many cans will be collected in 5 months. To do this, take the amount of cans collected each month and multiply it by the number of months. Set these values up in an equation.
This leaves you with:
3.75(5) = x

Multiply the values to get 18.75 pounds of cans.
So this fills the first blank.

For the second blank, you must subtract the number collected from the number that was the goal for the class.
This results in the expression:
20.5 - 18.75

Subtract the values to fill the second blank with 1.75 pounds.

Since they didn’t meet their goal, the last blank would be “less.”

I hope this helps! :)

jolie can read around 14 sentences per minute of her current novel. She wants to finish reading her book before the movie comes
alexandr402 [8]
Start at the beginning. 17 pages times 120 sentences is the first thing.
17 x 120 = 2040. So she has to read 2,040 sentences. If we now divide 2.040 by 14 pages/minute, we shoud get

2,040 divided by 14 = 145.7

The last thing to do, is changes those minutes into hours by dividing by 60.
2.42 hours.
