Answer:

[tex]T = 100[/tex]

Step-by-step explanation:

See attachment for parallelogram TRIK

Given

[tex]T = 5x[/tex]

[tex]I = 2(x + 30)[/tex]

Required

Determine T

Because T and I are opposite angles of the parallelogram, then they are congruent.

i.e.

[tex]T = I[/tex]

Substitute values for T and I

[tex]5x = 2(x + 30)[/tex]

Open bracket

[tex]5x = 2x + 60[/tex]

Collect Like Terms

[tex]5x - 2x = 60[/tex]

[tex]3x = 60[/tex]

Solve for x

[tex]x = \frac{60}{3}[/tex]

[tex]x =20[/tex]

Recall that:

[tex]T = 5x[/tex]

[tex]T = 5 * 20[/tex]

[tex]T = 100[/tex]

Answer:

x = ± [tex]\sqrt{20}[/tex]

Step-by-step explanation:

Given

x² = 20 ( take the square root of both sides )

x = ± [tex]\sqrt{20}[/tex]

which can be simplified to

x = ± 2[tex]\sqrt{5}[/tex]

[ ± means plus or minus ]

Answer:

$15.12

Step-by-step explanation:

{10 * 0.08 = 0.8

4 * 0.08 = 0.32} (Brackets are here so you can see what I did easier and so you could see how to do it mentally.)

[0.8 + 0.32 = 1.12]

14 + 1.12 = 15.12

David is buying a cheese wheel priced at $14 on 8% sales tax.

David's pays for the cheese wheel is $15.12 .

Given:

Before-tax, the price of cheese wheel = $ 14

Sales tax on cheese wheel = 8%

Sales tax is 8% of $14

[tex]=\frac{8(14)}{100} = \frac{112}{100} = 1.12[/tex]

So, the sales tax on the cheese wheel is $1.12

The total price of the cheese wheel, including tax = $ 14 +  $1.12 = $15.12

Therefore, David's pays for the cheese wheel is $15.12 .

Hi there!

[tex]\large\boxed{x = 8}[/tex]

Recall that all angles in a triangle sum up to 180°, therefore:

(9x + 3) + (5x - 2) + (11x - 21) = 180

Combine like terms:

9x + 5x + 11x + 3 - 2 - 21 = 180

25x -20 = 180

Add 20 to both sides:

25x = 200

Divide both sides by 25:

x = 8°

Answer:

Step-by-step explanation:

we know that the sum of the angles in a triangle is 180

(5x-2)+(9x+3)+(11x-21)=180

=5x-2+9x+3+11x-21=180

25x=180+20

25x=200

x=8

Answer:

48%

Step-by-step explanation:

If the coin is flipped 250 times, and lands on tails 120 times, set this up as a fraction. Put 250 on the bottom, and 120 on the top (because you want to know percentage of tails for 250 coin flips) to get 120/250. This is 0.48, to turn this into a percentage multiply by 100, 48%. You can check this answer by taking 0.48(250) and you will get 120.
