Can someone look at the pic at tell me if Im doing this correctly? I got x=14 ty

Answers

Answer 1

Answer:

x = 14

Step-by-step explanation:

→ Set up an equation

4x + 15 + 39 = 110

→ Simplify

4x + 54 = 110

→ Minus 54 from both sides

4x = 56

→ Divide both sides by 3

x = 14

Including a 6% sales tax, an inn charges $155.82 per night. Find the inn's nightly cost before tax is added.

Answers

we know the Inn is charging 155.82 and that's 100% plus 6%, namely 106% of an amout of say that is "x", being the 100%.

since we know that 155.82 is 106%, what is "x"?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 155.82&106\\ x&100 \end{array}\implies \cfrac{155.82}{x}=\cfrac{106}{100}\implies \cfrac{155.82}{x}=\cfrac{53}{50} \\\\\\ 7791=53x\implies \cfrac{7791}{53}=x\implies 147=x[/tex]

Answer:

-2/3= x

Step-by-step explanation:

square all the terms on both sides to get rid of the radicals:

[tex]1^{2} + (\sqrt{1-x} )^{2} = (\sqrt{2x+4}) ^{2}[/tex]

exponent 2 and the radical cancel each other:

1 + 1 - x = 2x + 4

2 - x = 2x + 4

like terms on each side ( when you move one term tp the other side, it changes its sign ):

2-x = 2x+4

2-4 = +x +2x

-2 = 3x

now to keep the x alone, divide both sides by 3:

-2/3 = 3x/3

-2/3= x

Step-by-step explanation:

Hypotenuse² =base² + altitude²

(3x + 4)² = (2x + 1)² + (3x)²

{Use (a+b)² = a² + 2ab + b²}

(3x)² + 2*3x+4 + 4² = (2x)² + 2*2x*1 + 1² + 9x²

9x² + 24x + 16 = 4x² + 4x + 1 + 9x²

9x² + 24x + 16 = 13x² + 4x + 1

0 = 13x² + 4x + 1 - 9x² - 24x - 16

13x² - 9x² + 4x - 24x +1 - 16 = 0

4x² - 20x - 15 = 0

a = 4 ; b =-20 ; c = -15

When a shape is translated, point A moves to (–1, 8). Where do the other vertices of each shape move to?

Answers

Answer: B' (5,8), C' (3,1)

Step-by-step explanation:

You can use the points A' (-1,8) and A (-2,-3) to find how many units point A was translated.

-2 + 1 = -1

-3 + 11 = 8

Then, you simply add 1 to the x-values of points B and C and 11 to the y-values of points B and C to get B' (5,8), C' (3,1).

The daily listening audience of an AM radio station is four times as large as that of its FM sister station. If 105,000 people listen to these two radio stations, how many listeners does the FM station have?

Answers

The number of listeners is given from the total number of listeners and

the ratio of the listeners between the two stations.

Required:

The FM sister station has 21,000 listeners

How is the given ratio of listeners used to find the number of listeners?

Given:

The daily listening audience of the AM station = 4 × The audience of the FM sister station

The number of people that listen to the two stations = 105,000

Required:

The number of listeners of the FM station

Solution:

The ratio of the listeners is 1:4

Let x represent the number of listeners of the FM sister station, we have;

The number of listeners of AM radio station = 4·x

Which gives;

4·x + x = 105,000

5·x = 105,000

[tex]x = \dfrac{105,000}{5} = \mathbf{21,000}[/tex]

The number of listeners of the FM sister station, x = 21,000

The number of listeners of he radio station = 21,000 × 4 = 84,000

if the shirt was 35% off, then you paid 65% of the cost

that value can be found by:

39 x .65 = 25.35 (this is the amount paid for the shirt)

sales tax of 6% on 25.35 is:

Two rectangles were used to form the following figure. Use the ruler provided to measure the
dimensions of the figure to the nearest quarter of an inch.
B
Which measurement is closest to the area of the shaded region of this figure in square inches?
F 19 in.
G11 in.
H 6 in.
8 in?

Answers

The area of a shaded region is the amount of space it occupies

The measurement that is closest to the area of the shaded region is 19 square inches

How to determine the area of the shaded region

Start by calculating the area of the big rectangle.

Assume the dimensions of the rectangle are 10 by 15 inches.

The area would be

[tex]A_1 =10* 15[/tex]

[tex]A_1 = 150 in^2[/tex]

Next, calculate the area of the small rectangle.

Assume the dimensions of the rectangle are 13 by 10 inches.

The area would be

[tex]A_2 =13* 10[/tex]

[tex]A_2 =130 in^2[/tex]

Next, calculate the difference between both areas

[tex]d = 150 - 130[/tex]

[tex]d = 20\ in^2[/tex]

19 is the closest to 20

Hence, the measurement that is closest to the area of the shaded region is 19 square inches (using the assumed values)
