Hanson is at a ball game with his family. he goes to the concession stand to buy soft pretzels and water bottles for everyone. a
guajiro [1.7K]

The system of equation that can be used to represent the situation is as follows:

  • x + y = 16
  • 2x + 3.5y = 47

The number of water bottle bought = 6

The number of pretzel bought = 10

Let

x = number of water bottle bought

y = number of pretzel bought

Hanson buys 16 items. Therefore,

  • x + y = 16

Hanson spends a total of $47. Therefore,

  • 2x + 3.5y = 47

<h3>Combined System of equation:</h3>
  • x + y = 16
  • 2x + 3.5y = 47

Therefore, let multiply equation(i) by 2

2x + 2y = 32

2x + 3.5y = 47

1.5y = 15

y = 15 / 1.5

y = 10

x + 10 = 16

x = 6

For the equation 2n - 3 = 7, what is the coefficient of the variable
scoray [572]

Answer:z

Then variable is n

Variable is an alphabet that depend on number. Then the variable there is n

And the coefficient of the variable is 2

The coefficient is the number behind a variable

And the value of the variable is

2n-3=7

Add 3 to both sides

2n-3+3=7+3

2n=10

Divide both side by 2

2n/2=10/2

n=5

One of the factors of the polynomial x3 − 5x2 is x + 3. What is the other factor?
olya-2409 [2.1K]
The answer is letter c. x2-8x+24-[72/(x+3)]. If you do not know how to solve this using the long division method, you can always evaluate the options through the process of elimination first. Since the degree of the other factor is already 1 (x to the power of 1), you know that option d. is not the correct answer because you know that the other factor must be raised to the power of 2. That leaves us with a, b and c. Working backwards and multiplying the given factor (x+3) with the factor in b, gives us x3-5x2+72. So from there, you know that you have to eliminate 72, which can be removed when it is subtracted by itself. Letter c does just that. Try multiplying (x+3) and option c for yourself :).
