The dimension of the rectangle is,

The length of the rectangle is 7 feet.

And the width of the rectangle is 8 feet.

Given that,

If the width of a rectangle is 9 ft less than twice its length and the perimeter is 30 feet,

We have to determine,

What are the dimensions of the rectangle?

According to the question,

Let, the width of the rectangle is W,

And the length of a rectangle is L = 2W - 9,

The perimeter of the rectangle is = 2(L+W)

Where perimeter is 30 feet,

Therefore,

[tex]30 = 2(2W-9+W)\\\\30 = 2(3W-9)\\\\30 = 6W-18\\\\30 + 18 = 12W\\\\48 = 6W\\\\W = \dfrac{48}{6}\\\\W = 8 \ feet[/tex]

And the length of a rectangle is,

[tex]L = 2W - 9, \\\\L= 2(8) - 9\\\\L = 16-9 \\\\L =7 \ feet.[/tex]

Hence, The dimension of the rectangle is, the length of the rectangle is 7 feet, and the width of the rectangle is 8 feet.

Answer:

Step-by-step explanation:

Since VW = VX ; Two sides are equal, then it is an isosceles triangle.

An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.

Given: m∠V = 50° ;

Since interior angles must total 180° the remaining 2 unknown angles must have a sum of 130°.

180° - 50° = 130°

130° / 2 = 65°

m∠W = 65° and m∠X = 65°

Answer:

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relation between triangle sides and angles. Here, we're given sides adjacent and opposite the marked angle, so the relation of interest is ...

  Tan = Opposite/Adjacent

  tan(68°) = 10/x

  x = 10/tan(68°)

  x ≈ 4.0 . . . feet

Answer: 20 miles

Step-by-step explanation:

Since the Uber charges $5.00 for the first mile you have to subtract that from the total which is 62.

62.00 - 5.00 = 57.00

Then you keep subtracting 3.00 from 57.00 or you can divide 57 by 3 because 57 is how much money is left and the Uber charges 3 dollars for each mile after the first.

57.00 divided by 3.00 is 19

Then add 1 to 19 which equals 20 miles. You add 1 to 19 because 19 is the amount of miles she goes but that doesn’t include the 1st mile.

Answer:

5,1

Step-by-step explanation:

7x + 4y = 39

2x + 4y = 14

since, the 4y same for both equation then we can eliminate the 4y by subtracting the two equation

7x + 4y = 39

2x + 4y = 14

---------------- -

5x + 0 = 25

5x = 25

x = 25/5 = 5

then we can input (subtitute) the value of x into the equation, I choose 2x + 4y = 14

2x + 4y = 14

2(5) + 4y = 14

10 + 4y = 14

4y = 14 - 10

4y = 4

y = 4/4 = 1

or if your teacher ask you to use elimination to find the value of x we can write like this

7x + 4y = 39

2x + 4y = 14

make the coeficient of x in both equation same

7x + 4y = 39 (x2)

2x + 4y = 14 (x7)

so

14x + 8y = 78

14x + 28y = 98

--------------------- -

0 - 20y = -20

-20y = -20

y = (-20)/(-20) = 1 (same answer right)

so the correct answe is

Hello! :)

[tex]\large\boxed{q = -3.4}[/tex]

-13(q + 4) = 7q + 16

Distribute the coefficient outside of the parenthesis:

-13(q) - 13(4) = 7q + 16

Simplify:

-13q - 52 = 7q + 16

Isolate for q by subtracting 7q from both sides:

-13q - 7q - 52 = 7q - 7q + 16

-20q - 52 = 16

Add 52 to both sides:

-20q - 52 + 52 = 16 + 52

-20q = 68

Divide both sides by -20:

-20q / (-20) = 68 / (-20)

q = -3.4

➤ How to solve ?

⠀⠀⠀⠀

That's quite easy but you need to recall the BODMAS rule .

⠀⠀⠀⠀

BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction

⠀⠀⠀⠀

In this equation we will solve the bracket then we will apply further BODMAS rule

⠀⠀⠀⠀

━━━━━━━━━━━━━━━━━

➠ - 13 ( q + 4 ) = 7q + 16

➠ -13q - 52 = 7q + 16

Now, we will bring the variable on left hand side and constants on right hand side

➠ -13q - 7q = 52 + 16

➠ -20q = 68

➠ q = 68/ -20

➠ q = 34/-10

As we have 10 in the denominator we can directly put the decimal .

➠ q = -3.4

∴ The value of q is - 3.4.

Equivalent expression to[tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]  determine.

Evaluation is defined as finding a solutions to mathematical problems.

Here, we have [tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]
[tex]=\frac{sin(x/2)tan(x/2)}{1-cos(x)}\\ =\frac{sin(x/2)\frac{sin(x/2)}{cos(x/2)} }{2sin^2(x/2)} \\= \frac{sin(x/2)^2}{2cos(x/2)sin^2(x/2)}\\ =1/2cos(x/2)\\=\frac{1}{2\sqrt{(cos(x)+1})/2 } \\=\frac{1}{\sqrt{2(1+cos(x))} }[/tex]

Thus, the equivalent expression to[tex]\frac{ sin(x/2)tan(x/2)}{1-cos(x)}[/tex]  is  [tex]\frac{1}{\sqrt{2(cosx+1)} }[/tex].

Answer:

I can only assume that the entire 1-4x is divided by 2x, and 4 by all of 1 - 5x.  You can guarantee more accurate results by using brackets where appropriate.  If I read that expression with the correct notation, it reads as [tex]1 - \frac{4x}{2x} + 1 = \frac{4}{1} - 5x[/tex].

Assuming instead that it's meant as [tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}[/tex], we can solve it as shown below, giving us x values of 1 and 3/20 (or 0.15).

Step-by-step explanation:

First let's reformat this to the usual ax² + bx + c format:

[tex]\frac{1 - 4x}{2x + 1} = \frac{4}{1 - 5x}\\(1 - 4x)(1 - 5x) = 4(2x + 1)\\1 - 5x - 4x + 20x^2 = 8x + 4\\20x^2 - 5x - 4x - 8x + 1 - 4 = 0\\20x^2 - 17x - 3 = 0[/tex]

Let's solve it with the quadratic formula:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}\\\\x = \frac{17 \pm \sqrt{-17^2 - 4\times 20 \times( -3)} }{2\times20}\\\\x = \frac{17 \pm \sqrt{289 + 240} }{40}\\\\x = \frac{17 \pm 23 }{40}\\\\x = 1, \frac{3}{20}[/tex]
