The model represents an equation. What value of X makes the equation true?

Mathematics

Anettt [7]3 years ago

Answer:

D. 3

Step-by-step explanation:

Assuming the model represents an equation, the following can be deduced:

On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:

3x + 6

On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:

2x + 9.

The model would represent the equation below:

3x + 6 = 2x + 9

Solve for x

3x + 6 - 2x = 2x + 9 - 2x (Subtracting 2x from both sides of the equation)

x + 6 = 9

x + 6 - 6 = 9 - 6 (subtracting 6 from both sides of the equation)

x = 3

The constant of the proportional relationship graphed in this problem is of 10.

<h3>What is a proportional relationship?</h3>

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

y = kx

In which k is the constant of proportionality.

In this problem, the points on the graph are: (0,0), (2,20), (4,40), ..., hence the constant is:

k = 40/4 = 20/2 = 10.

Including a 5% sales tax, an inn charges $231 per night. Find the inn's nightly cost before the tax is added
Kamila [148]

The inn's per night cost before tax is $220.

Step-by-step explanation:

Given,

Sales tax = 5% = \frac{5}{100} = 0.05

Per night charges including sales tax = $231

Let,

x be the per night charges.

Per night charges + 5% sales tax of per night = 231

x+0.05x=231\\1.05x=231\\

Dividing both sides by 1.05

\frac{1.05x}{1.05}=\frac{231}{1.05}\\x=220

The inn's per night cost before tax is $220.
