Answer:

x = 3

y = -1

Step-by-step explanation:

in this system, we are given that y = x - 4

this means that we can take the other equation and replace y with x - 4:

so 2x - 3y=9 turns into

2x -3 (x - 4) = 9

distribute -3 to x and -4:

2x - 3x + 12 = 9

add like terms and subtract 12 from both sides

-x = -3

divide both sides by -1 to get rid of the negative on x:

x = 3

now we have the value of x, so we can replace the x in y = x - 4 with the value we just got

so y = x- 4 turns into

y = (3) - 4

solve and you get

y = -1

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:

20%

Step-by-step explanation:

if the 100% of the price is $250 and the discount is $50 then to find what percent $50 we multiply 100 by 50 then divide it with 250

100 × 50 ÷ 250 = 20

Answer: x = 7

Step-by-step explanation:

7x+9=58

8x+2=58

These are congruent angles so they are the same value.

Answer:

which one do you need?

Step-by-step explanation:

Answer:

55

Step-by-step explanation:

2x+5 x-5 combine these to get 3x

then you would divide 180 by 3

so u would get 60 = x

60-5 =55

I thank it's 55 It wont let me post it because its too short

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]

Step-by-step explanation:

Using the rise over run strategy, you can get this answer by...

1. Look at the line and graph 2 points. ( 1 , 1 ) & ( 2 , 2 ).

2. Do the rise over run thing. ( how am I going to get from 1 point to the other.)

You get to it by rising 1 and running 1. The pattern is self explanatory.

3. Divide rise over run and the quotient is your answer

1 divided by 1 is 1.

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 .
