Write a word phrase for the algebraic expression 5/x

1 answer:

6 0

Here’s an example:
John spent an hour mowing his neighbor’s yard. His neighbor’s said that he will receive his pay the next day. John wants to buy his brother a 5$ birthday gift, and wants to take at least 50% of his check. Therefore, John set up the following equation to calculate the least amount that his paycheck would be for 5$ to be 50% of it.
John’s equation: 5/x=50/100.
After Johns calculations, he figures that his check must be a minimum of 10$ for his paycheck (X) for 5$ to be 50% of it.

On a certain IQ test, eleven people averaged a 101.5. A certain reality TV star took

dem82 [27]

Answer:

59.98

Step-by-step explanation:

To find the average of a set of numbers, we sum them all together and divide them by the size of the set. Here, we start out with 11 IQ scores. We don't know what they are, but we can still set up an equation with the information we do have. Let's call the sum of those 11 score s. The average must be s/11, which we know is 101.5. With that, we can set up and solve and equation for s:

$\dfrac{s}{11}=101.5\\s=101.5(11)\\s=1116.5$

Let's call the score of the reality TV star r. If we add their score to the set, we now have 12 scores. The sum of those scores is gonna be the sum of the previous scores, 1116.5, plus the reality TV star's score, r. To find the average, we divide the sum by 12. Finally, we're told that this average is exactly 98.04. Putting all of this into an equation gives us

$\dfrac{1116.5+r}{12}=98.04$
