Answer:

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

**What is****simplification?**

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.

Confirmed in class

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

Answer:

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

n= number of Christmas gift

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.

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:

- 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.
- 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).
