Find three consecutive odd integers such that the sun of the largest and twice the smallest is 25
Answers
Let's call the our odd numbers ,
, and
, in ascending order. It can be said then that
(It is the next odd number after
) and
(It is the second consecutive number after
).
Additionally, we can say:
Now, how about we substiute in the value for we found in the first paragraph for
in the preceeding equation? This gives us:
- Substitute
- Add like terms
- Subtract 4 from both sides
- Divide both sides by 3
We have found that the smallest number is 7. Substituting this into the equations we found in the first paragraph, we find:
The numbers are 7, 9, and 11.
Answer:
The three correct numbers are 7, 9, and 11.

Answer:
In 10 years they would be the same, so in 11 years Michigan's population will be greater.
If you add 9.9 by 0.6 10 times you would get an answer of 15.9, and the same with 11.4 plus 0.5... So if you did it one more time Michigan would get 16.5 and Ohio would get 16.4.
So the answer is 11. (10 would equal the same amount)

Use 0-9 only once figure out the x
Answers
3x means 3 times x or x+x+x
xx means x times x or x(x)
so
x+5+x+x+x+x+x+5=x+x+6+x+x
add like terms
6(x)+10=4(x)+6
not sure about the 0-9 part so I will disreagrd for now, please ask for correction later
6x+10=4x+6
subtract 4x from both sides
2x+10=6
subtract 10 from both sides
2x=-4
divide both sides by 2
x=-4/2=-2 (divide or multiply by different signs and get negative)
x=-2

B; 25.65+13.23+6.35=45.23
To do this mentally just add the 2 decimals places together first (1.23). Then just add the whole numbers (44). Then add the 2 numbers together, 44+1.23=45.23
