One angle measures 54 more degrees than 3 times another angle. The angles are supplementary. What are their measures

The angles are supplementary so they add up to 180 degrees. The equation would be

x + 3x + 54 = 180
4x = 180-54
4x = 126
x = 31.5 degrees

1st angle is 31.5 degrees
2nd angle is 3x+54 = 148.5 degrees.

To check 148.5+31.5 = 180

Dora bought a bottle of nail polish that was marked down by 20 percent from its original price of $4.50. Including a 9 percent s
igomit [66]

Answer:

3.92$

Step-by-step explanation:

The first step is to deduct 20% of 4.50 from 4.50.

20% of 4.50 is 0.2 x 4.50 = .90

4.50 - 0.90 = 3.60

That's the new price without the sales tax.

Now we need to add 9% of 3.60 to 3.60 to get the final cost.

9% of 3.60 is .09 x 3.60 = 0.32

3.60 + .32 = $3.92

Hope it helps.. If yes mark me BRAINLIEST

What is the area of a square with a 80 ft. Perimeter
slega [8]

Answer:

400 sq. ft.

Step-by-step explanation:

We gotta find the length of a side:

First, we divide 80 by 4, because the perimeter of a square is (4 x side):

80 ft. / 4 = 20  ft.

Second, we doing the normal area of a square equation:

20^{2} = 400 square ft.

Which leads to out answer of 400 sq. ft.

A company manufactures and sells video games. A survey of video game stores indicated that at a price of $66 each, the demand wo
AysviL [449]

Answer:

y=-30x+2380

Step-by-step explanation:

x\rightarrow represent price per video game.

y\rightarrow represent demand.

The linear equation in slope intercept form can be represented as:

y=mx+b

where m is slope of line or rate of change of demand of game per dollar change in price and b is the y-intercept or initial price of game.

We can construct two points using the data given.

When price was $66 each demand was 400. (66,400)

When price was $36 each demand was 1300. (36,1300)

Using the points we can find slope m of line.

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{1300-400}{36-66)}

m=\frac{900}{-30}

m=-30

Using point slope form of linear equation to write the equation using a given point.

y-y_1=m(x-x_1)

Using point (66,400).

y-400=-30(x-66)

⇒ y-400=-30x+1980    [Using distribution]

Adding 400 to both sides:

⇒ y-400+400=-30x+1980+400

⇒y=-30x+2380

The linear relationship between price and demand can be written as:

y=-30x+2380
