Answer:

x = 40

Step-by-step explanation:

The angles are vertical angles.  We know that vertical angles are equal

120 = 3x

Divide each side by 3

120/3 = 3x/3

Answer:

40

Step-by-step explanation:

I forgot what you would call this, but basically 3x = 120. both of the angles are the same. So divide both sides of the equation by 3. 3x/3 = 120/3 and your answer is 40.

It's a bad explanation but I hope it helps!

The revenue of a company that makes backpacks is given by the formula R = 34.S0x, where x represents the number of backpacks sol
alexgriva [62]

Answer:

Revenue = 1380

Step-by-step explanation:

Given:

Revenue means the sales or turnover of a company when it sells its products. In other words, it is nothing but the income of a company on selling the products.

Here, the company is selling backpacks. So, revenue is the amount earned by the company on selling 'x' backpacks. The linear model to represent the same is given below.

The revenue received from selling 'x' backpacks is given as:

R=34.50x

Number of backpacks sold (x) = 40

Now, in order to find the revenue received on selling 40 backpacks, we need to plug in 40 for 'x' in the equation above and solve for the revenue, 'R'.

On plugging 40 for 'x', we get:

R=34.50\times 40\\\\R=1380

Therefore, the revenue received by the company on selling 40 backpacks is 1380.

A car rental company charges, y, for x, days. Days 3 4 5 6
VMariaS [17]

The equation of the car rental company in the form y = kx is; y = 18.50x

The equation y = kx is such that;

  • y = dependent variable

  • x = independent variable

  • k = constant of proportionality.

In essence; to determine the constant of proportionality, k in this case;

  • k = y/x

Since the company charges, $55.50 for 3 days; we have;

By evaluation k = $55.50/3

  • k = 18.50.

A constant rate of change means the variation in the dependent variable as dependent on the independent variable is constant

In a large apartment building, 35 of the apartments have a balcony and 55 do not.
Masteriza [31]
Hello!

You first have to find the total amount of apartments

35 + 55 = 90

There are 90 apartments

Then you find the percentage of them have a balcony

You do this by taking the amount of apartments that have a balcony over the total amount of apartments

35/90 = 0.39

0.39 as a percent is 39%

The answer is 39/100 or 39%

Hope this helps!
