The overall cost is $50.33. you now subtract out the prices you know. The easiest way to do that is to add them up; 17.97+25.49. That is 43.46.

The next step is to subtract 43.46 from 50.33. 50.33-43.46=6.87. That is the price of all the pairs of socks put together.

to find out how much one pair is, you then divide 6.87 by 3. That is 2.29.

The answer is $2.29

I hope this helps!

What is the fifth term in the binomial expansion of (x + 5)^8?O 175,000x³O 43,750x4O 3,125x5O 7,000x
enyata [817]

Solution:

Given the expression below

(x+5)^8

Applying the binomial theorem formula

\begin{gathered} \left(a+b\right)^n=\sum_{k=0}^n{\binom{n}{k}}a^{n-k}b^k \\ Where \\ a=x \\ b=5 \\ n=8 \\ k=4\text{ i.e. fifth term} \end{gathered}

For the fifth term, i.e

\sum_{k=4}^8{\binom{8}{4}}x^{8-4}5^4=\frac{8!}{4!(8-4)!}\cdot x^4\cdot(625)=(70)(625)(x^4)=43750x^4

Hence, the fifth terms is

43750x^4

5.
Ostrovityanka [42]

Answer:

integers, rational numbers

Explanation:

Integers are any whole number (positive or negative). -5 is a whole number, not a fraction or decimal.

Rational numbers can be written in the fraction form a/b where a and b are both integers and b does not equal 0. -5 can be written as -5/1.
