two times a number n plus three
Answer:
I believe 0.75 is the answer. Here is my work:
Step-by-step explanation:
1. 250 divided by 5 = 50 (this is to get 1/5 of 250)
2. 250 divided by 2 (because 1/2 is equivalent to 50% of the overall number) = 125
3. 50 + 125 = 175
4. 250-175 = 75
5. 75 can be converted to 0.75 as a decimal by moving 2 digits over.
Therefore, out of the 250 seventh grade students, 0.75 are in other electives.
Also, I'm in 7th grade so this is my work, I'm sure there are other ways of solving this, too. Please do not add this answer if you don't believe I'm right.
Thanks for your time, and have a nice day! : )
