a student has some $1 and $5 bills in his wallet. He has a total of 13 bills that are worth $33. How many of each type of bill does he have?

Answers

Answer 1
Answer:

Answer: The number $1 bills is 8 and the number of $5 bills is 8.

Step-by-step explanation:

Let x denotes $1 bills and y be denotes $5 bills.

Then , we have the following equations :-

x+y=13-------(1)\n\nx+5y=33-------(2)

Subtracting equation (1) from (2), we get

4y=33-13=20\n\n\Rightarrow y=\frac{20}[4}=5

Substitute y=5 in equation(1), we get

x+5=13\n\n\Rightarrow\ x=13-5=8

Hence, the number $1 bills is 8 and the number of $5 bills is 8.
Answer 2
Answer: He has 6 $5 dollar bills and 3 $1 dollar bills

Tomas learned that the product of the polynomials (a b)(a2 – ab b2) was a special pattern that would result in a sum of cubes, a3 b3. his teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y. which product should tomas choose? (2x y)(2x2 2xy – y2) (2x y)(4x2 2xy – y2) (2x y)(4x2 – 2xy y2) (2x y)(2x2 – 2xy y2)

Answers

The polynomial (a + b)(a² – ab + b²) is reconstructed as (2x + y)(4y² – 2xy + y²), then the correct option is C.

What is polynomial?

Polynomial is an algebraic expression that consists of variables and coefficients. Variables are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Tomas learned that the product of the polynomials (a + b)(a² – ab + b²) was a special pattern that would result in a sum of cubes, a³ + b³.

His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if a = 2x and b = y.

Then the polynomial equation will be

(2x + y)(4y² – 2xy + y²)
