What do the two variables represent?

The two variables represent the number of nights or squires at the jousting contest.

Write a system of equations.

let k = number of knights and let s = number of squires

3k + 2s = 32

2k + s = 19

How many knights are there? <u>6</u>

How many squires are there? <u>7</u>

Solving:

solve for s in the second equation by subtracting 2k from both sides

2k + s = 19

s = 19 - 2k

substitute into first equation

3k + 2(19-2k) = 32

distribute 2 into 19-2k

3k + 38 - 4k = 32

add like terms

-k + 38 = 32

subtract 38 from both sides

-k = -6

divide by -1

k = 6

subsitute into the equation for s

s = 19 - 2k

s = 19 - 2(6)

s = 19 - 12

s = 7

The solution to the equation is x = 7 , -2 , Option C and D is the right answer.

<h3>What is an Equation ?</h3>

An equation is a mathematical statement formed when two algebraic expression are equated by an equal sign.

It is given that the equation is

\rm 3 +\sqrt{3x - 5}= x

Taking square on both sides

3x-5 = (x-3)²

3x-5 = x² +9 -6x

x² -9x -14 = 0

x² -7x +2x -14 = 0

x(x-7) +2(x-7) = 0

(x-7)(x+2) = 0

x =7 , x = -2

Therefore the solution to the equation is x = 7 , -2 , Option C and D is the right answer.

A pharmaceutical company sells bottles of 500 calcium tablets in two dosages: 250 milligram and 500 milligram. Last month, the c
lorasvet [3.4K]

Answer:

the price of a 250-milligram bottle is $8

he price of a 500-milligram bottle is $12

Step-by-step explanation:

Let,

x = price of a 250 mg dosage

y = price of a 500 mg dosage

Last month, the company sold 2,200 bottles of 250-milligram tablets and 1,800 bottles of 500-milligram tablets. The total sales revenue was $39,200

2200*x + 1800*y = 39200

The sales team has targeted sales of $44,000 for this month, to be achieved by selling of 2,200 bottles of each dosage.

2200*x + 2200*y = 44000

The system of equations result

2200*x + 1800*y = 39200

2200*x + 2200*y = 44000

We can easily solve it by graphing both equations, please see attached image

The answer is

x = $8

y = $12
