I Think of a number. If i subtract 8 from it and multiply the difference by 3 the result is 21. What is the number i am thinking of?
I'm sorry. I goofed. The problem states that the difference is multiplied, not divided, by 3.
3 (n - 8) = 21
3n - 24 = 21
3n = 45
n = 15
The answer is supposed to be 15
3(×-8)=21
3×-24=21
3×-24+24=21+24
3×÷45÷3
×=15
15
To find the number you are thinking of, we can solve the equation you provided.
Let's call the number you are thinking of "x".
According to the information given, if you subtract 8 from x and multiply the difference by 3, the result is 21. Mathematically, this can be represented as:
( x - 8 ) * 3 = 21
Now, let's solve for x step by step:
1. Distribute the 3 to both terms inside the parentheses:
3x - 24 = 21
2. Add 24 to both sides to isolate the term with x:
3x = 21 + 24
3x = 45
3. Divide both sides by 3 to solve for x:
x = 45 / 3
x = 15
Therefore, the number you are thinking of is 15.
Thanks for the answers
And I will need more
i hate this i dont understand
(n - 8) / 3 = 21
n - 8 = 63
n = 71
