hello :)
so let me just give you the answer first:
2/3 * d = 32 2/3
here is why
so since the sentence said 2/3 PER day, then d (the number of days) multiplied by the time spent each day playing piano should give you how much time was spent in total over the certian number of days.
the 32 2/3 is just the amount of time ellie spent (as you have said)
so, this equation would be the correct one.
i hope this helped you out! please vote me for brainliest and have splendid day!
Answer:
The weight is 4 pounds :D
Step-by-step explanation:
4(3-7x). Since there are 4 sides in a square, you multiply one length by 4 to get the perimeter. 4(3-7x) simplifys to 12-28x.
The amount of work done by Kalon in an hour is equal to 1/4. This is based on his time to finish the job. Letting x be the number of hours Marna can finish the job alone will let her finish 1/x of the job in an hour. If their rates are added together and multiplied by the number of hours they worked together, the product should be one whole job.
(1/4 + 1/x)(1 5/7) = 1
The value of x is 3. Therefore, it will take 3 hours for Marna to clean the chimney alone.
