# Simplify the polynomial

The polynomial after simplification is obtained as + 9x + 3.

What issimplification?

In mathematics, reducing an expression, fraction, or problem to a simpler form is referred to as simplification. With calculations and solution, the problem is made simple. Make something simpler by simplifying it.

We are given a polynomial as

5x - 5 + + 4x - + 8

Now, in order to simplify the given polynomial, we will combine the like terms of the polynomial.

On combining the like terms, we get

+ 9x + 3

Hence, the polynomial after simplification is obtained as + 9x + 3.

Paige rides her bike around town. She can ride one half of a mile in 1 30 ith of an hour. If she continues to ride at the same pace, how many miles could she travel in 1 hour?

We have been given that Paige can ride one half of a mile in 1/30 th of an hour. And we have to found the distance traveled in 1 hour if she continues to ride at the same pace.

Let d be the distance traveled in 1 hour.

In 1/30 th of an hour distance traveled is 0.5 mile

Hence, in 1 hour the distance traveled is given by

Therefore, she will travel 15 miles.

She could travel 15 miles in an hour

Six college buddies bought each other Christmas gifts. They spent:________.1. \$178.622. \$247.583. \$228.454. \$176.645. \$180.226. \$268.45What was the mean amount spent? Round answer to the nearest cent.a. \$243.96b. \$213.30c. \$319.95d. \$255.96

B. \$213.30

Step-by-step explanation:

Mean amount spent on Christmas gifts = Σx / n

Where,

Σ= sum of

x= cost of each Christmas gifts

Mean amount spent on Christmas gifts = Σx / n

= ( \$178.622 + \$247.583 + \$228.454 + \$176.645 + \$180.226 + \$268.45 ) / 6

= \$1,279.98 / 6

= \$213.33

Round to the nearest cent

= \$213.30

Option b is the correct answer

The mean amount spent by six college buddies on Christmas gifts, They spent:  approximately \$213.33 when rounded to the nearest cent.

### Explanation:

The process is quite straightforward and involves the principles of statistics, particularly the calculation of the arithmetic mean. Here are the steps we can follow to solve this problem:

1. First, we need to find the total amount spent. We do this by adding the amounts together: \$178.62 + \$247.58 + \$228.45 + \$176.64 + \$180.22 + \$268.45. When we add these values, we get a total of \$1,279.96.
2. Next, we need to calculate the mean, which in statistics is also commonly referred to as the average. Since there were six buddies, we divide the total amount (\$1,279.96) by 6. When we do this, we find that the mean or average amount spent is approximately \$213.33 (when rounded to the nearest cent).
