Hey ya'll, my assignment asked me.....Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework.

He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.
Then, i answered with: To find a percentage you just have to put the percent in decimal form then you multiply. 125% = 125/100 125% = 125/100 = 1.25 By doing this, we get 1.25, which is the same as 125% in decimal form. Therefore, Evan was correct. He spent 125% more time doing homework this week. IS THAT CORRECT

Answer:

Evans is correct.

Step-by-step explanation:

Evan spent 20 hours doing homework last week. This week he spent 25 hours doing homework. He says that he spent 125% more time doing homework this week. Is he correct? Show your work to justify your decision.

We know that 125% of 20 hours (last week) = 25 hours, so Even IS correct.

Note that Increase or Decrease is relative to the ORIGINAL value, in this case is 20 hours.

Answer:

No he is wrong

Step-by-step explanation:

Evan was not correct 125% means he over doubled his time doing homework. To double his time he would need 40 hours, and he only did 25.

Increase: 5 hrs

Percent of increase: 20%, because 5/25=20%

-4c - 11 = 4c +21<br><br> Please help! I have literally no idea
MissTica
<span> -4c - 11 = 4c +21                                        add 4c to both sides
</span>
<span> -4c - 11 + 4c = 4c + 21 + 4c                        simplify

- 11 = 8c + 21</span>                                <span>               subtract 21 from both sides

- 11 - 21 = 8c + 21 - 21                                </span><span>simplify

- 32 = 8c                                                      divide both sides by 8

c = - 4


That's it






</span>

I hope you got the idea
