PLEASE HELP ME I NEED THIS DONE TODAY PLEASE HELP I KNOW NO ONE WILL BUT IT'S 7TH GRADE MATH PLEASE HELP
Andrei [34K]

Answer:

Overall answer: 10 1/9 - 1 5/18x (Most simplified answer)

Step-by-step explanation:

First you have to do all the Distributive property which the answer would be:

2 1/2 - 1/2x + 3 1/9 + 8/9x + 1/6x - 5/18x + 2 14/18 + 1 13/18

Then you have to find the common demoninator which would be 18

After that you have to put them in the correct order since there is two different terms which would be:

2 9/18 + 3 2/18 + 2 14/18 + 1 13/18 - 9/18x + 16/18x + 3/18x - 5/18x

After that you solve the problem which in the end after solving both terms it ends up as..:

10 2/18 - 1 5/18x

and I think that is as simplified as you can go term wise.

I hope this helps and I hope I didn't make a mistake :D

\dfrac{6-2i-4+6i}{2} \\\\=\dfrac{2+4i}{2}\\ \\=1+2i

Hence, midpoint of a segment in the complex plane with endpoints at 6 -2i and -4 + 6i is:

Lisa's car averageed 15 miles per gallon of gasoline. After a tune up she noticed she was getting 18 miles per gallon of gasolin
Lady_Fox [76]

Answer:

  • Reduction of Gasoline Consumption
  • Increase in Miles Per Gallon by 3.

Step-by-step explanation:

Previous Rate of Gasoline Consumption = 15 miles per gallon

Rate of Gasoline consumption after Tune Up = 18 miles per gallon

The difference in Gasoline Consumption = 18-15 =3 miles per gallon

Since the difference is positive, Lisa noticed she got 3 extra miles for every gallon of gasoline. That is, her gasoline consumption reduced.
