9+2n=5n this is how you would set up the problem
9+2n-2n=5n-2n then you subtract the number with the variable on each side
9=3n this is what it leaves you with
9/3=3n/3 then you divide three by both sides to get the variable by itself
3=n then you have your answer
Hope this helps you!!
multiples: 5, 10, 15 + 2 = 17 Answer: 15
1/2 times (1 - square root of 5), or 1/2 times (1 + square root of 5)
You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
10
( 5 + 3x )
Yes.
the number is 3 because 3 times 5 is 15 plus 2 is 17
multiples: 5, 10, 15 + 2 = 17 Answer: 15
because the number are the same /example2 times 3 equals 6. 3 times 2 equals 6
2 x 3 x 5 + 1 = 31
100101 1 times 2^0 = 1 PLUS 0 times 2^1 = 0 PLUS 1 times 2^2 = 4 PLUS 0 times 2^3 = 0 PLUS 0 times 2^4 = 0 PLUS 1 times 2^5 = 32 EQUALS 37
It is not possible to answer the question since it is incomplete. The number between "plus" and "equals" is missing.
1/2 times (1 - square root of 5), or 1/2 times (1 + square root of 5)
You take 4 times 5 which is 20 then 3 plus 2 which is 5. Add 20 plus 5 and you get 25. That's the answer.
(4 times 3) plus 2 plus 1
So 5 must be the other two times the number which means the number is 2.5.
if the number is the same: 2x + 3x = 13 5x = 13 x= 13/5
