This ones a bit of a trick question, since whether the integers are even or odd doesn't really matter. What does matter, is that consecutive odd integers are 2 numbers apart (as are consecutive even integers).
So again, if the first of the odd integers is the variable n
the consecutive odd integers after it can be written as:
n+2 , n+4, etc...
So the sum of four consecutive odd integers can be written as:
sum = n + (n+2) + (n+4) + (n+6)
Simplify:
sum = 4n + 12
And finally rearrange to solve for n:
= n
This can also be written as:
- 3 = n
Whichever way you prefer.
7/10
9/10 - ____ = 2/10
9 - 7 = 2
So, 9/10 - 7/10 = 2/10 or 1/5
Answer:
Step-by-step explanation:
300 - 25 divided by 3 subtracted by 200 plus 1000 minus 350:
- 300 - 25/3 - 200 + 1000 - 350 =
- 300 - 8.(3) - 200 + 1000 - 350 =
- 741.(6)
The answer to your question is 2.5 hope this helps
The answer is -7
2x-3(x+4)=-5
Multiply by -3
2x-3x-12=-5
Collect like terms
-x-12=-5
Move constant to the right to change its sign
-x=-5+12
Add
-x=7
Change the signs
x=-7
