After earning interest, the balance of an account is $420. The new balance is 7/6bof the original balance. Write an equation that can be used to find the original balance b of the account.

There are a total of 900 /999-99/ 3-digit numbers. And they are 900 consecutive numbers, 1/6th of these should be divisible by 6, 900/6=150 numbers. So the answer to your question is answer is... 150! :3

One can miss up to 24 questions and still achieve an 80% score.

In order to calculate the points each question is worth and determine how many questions you can miss while maintaining an 80% score.

To find the points each question is worth, we divide the total points by the number of questions. Let's assume the test is out of 100 points, which is a common scale. Therefore, each question would be worth or approximately 1.05 points.

Now, let's determine how many questions you can miss while still achieving an 80% score (which is 80 out of 100 points). We'll set up an equation to solve for the maximum number of questions you can miss, denoted by "x":

To solve for "x," first, we'll simplify the equation:

Next, we'll isolate "x" by multiplying both sides by 95:

Now, isolate "-100x" by subtracting 7600 from both sides:

Finally, divide both sides by -100 to solve for "x":

So, you can miss up to 24 questions and still achieve an 80% score.
