I'm thinking of a number.
When I multiply it by 6 and subtract 30, the answer is 78
What is Noah's number?
40 days and 40 nights.
Now, to find Ali's number, solve
6x-30 = 78
To find Noah's number, we can set up an algebraic equation based on the information given.
Let's assume the number Noah is thinking of is represented by 'x'. According to the given information, when this number is multiplied by 6 and then subtracted by 30, the result is 78.
We can write this equation as:
6x - 30 = 78
To find the value of 'x', we can solve this equation by isolating 'x' on one side of the equation. To do this, we'll perform the following steps:
1. Add 30 to both sides of the equation:
6x - 30 + 30 = 78 + 30
6x = 108
2. Divide both sides of the equation by 6:
6x/6 = 108/6
x = 18
Therefore, Noah's number is 18.
