In a cryptarithm, each letter is assigned its own unique digit. In the cryptarithm shown (where MATH is 3 times FUN), FUN is a 3
ANEK [815]

The 3 digit number that is FUN is; 678

<h3>What is the combination of the numbers?</h3>

We are told that MATH is 3 times the word "FUN".

We are also told that each letter is assigned a unique number and that no leading digit can be zero and that the digits must be consecutive.

Now, product of 789 by 3 gives;2367.

Each letter should have a unique letter and so that is not the correct sequence.

Let us try the product of 678 by;

678 * 3 = 2034

This fulfils the condition of the question because each letter has a unique digit, the lead digit is not zero and the numbers are consecutive numbers in increasing order.

Thus, the 3-digit number that is FUN is 678.

Which equation can be used to describe the direct variation function between E, the total earnings in dollars, and h, the number
kipiarov [429]

Let us take a sharp point for the graph.

In 4 hours total earning is $30.

Therefore, earnings per hours would be 30/4 = $7.5 per hour.

Are given direct variation between Total earnings(E) and Number of hours worked(h).

So, we can setup a direct variation as

Total earnings = Earning each hour * Number of hours.

Therefore, direct variation function would be

E=7.5*h.

Therefore, the direct variation function between E, the total earnings in dollars, and h, the number of hours worked is E = 7.5h.
