right triangle...

Hope this helps...

Answer:

1. x = 65

2. x = 40

3. x = -7

4. x = -4

5. x = -7

6. x = 4

Step-by-step explanation:

Angles in a triangle always add up to 180 degrees.

Thus, for each triangle you can write an equation setting the sum of the three angles equal to 180, and solving for x.

1. 180 = 80 + 35 + x

   180 - (80 + 35) = x

   180 - 115 = x

   65 = x

2. 180 = 70 + 70 + x

   180 - (70 + 70) = x

   180 - 140 = x

   40 = x

3.  180 = 76 + 41 + (x+ 70)

    180 - (76 + 41) = x + 70

    180 - 117 = x + 70

    63 = x + 70

    63 - 70 = x

    -7 = x    

4. (the red square means its a right angle = 90 degrees)

   180 = 90 + 25 + (x + 69)

   180 - (90 + 25) = x + 69

   180 - 115 = x + 69

   65 = x + 69

   65 - 69 = x

   x = -4

5. 180 = 50 + (57 +x) + (x + 87)

   180 - 50 = (57 +x) + (x + 87)

    130 = (57 +x) + (x + 87)

  combine like terms

  130 =  144 + 2x  

  130 - 144 = 2x

  -14 = 2x

   -7 = x

6. 180 = 80 + (9x + 4) + (16x - 4)

   180 - 80 = (9x + 4) + (16x - 4)

   100 = (9x + 4) + (16x - 4)

   combine like terms

    100 = 25x + 0

    100 = 25x

    4 = x

Answer: D , p = n (800 - 450) - 3000

Step-by-step explanation: Firstly, you have to account for how much money Rafael is making off of each computer (800 - 450). That factor is then multiplied by the variable "n" which represents the amount of computers sold. Lastly, since this is an equation to calculate his monthly profits, you have to subtract the rent that he is paying ($3000) from the total profit that he made off of selling the computers. Therefore, giving you the equation

P (profit) = n (amount of computers sold) (800-450) - 3000 (rent).

The equation that represents Rafael's monthly profit selling 'n' numbers of computers is D. P = n(800 - 450) - 3000.

An equation represents equality for the terms that are on the both side of the equal sign.

Given Rafael buys computers for 450 dollars and sells them for 800 dollars each.

He also had to pay 3000 dollars for rent and utilities for the store and the number of computers sold in each month is given by 'n'.

∴ The equation that represents his profit(P) in a month is,

P = n(800 - 450) - 3000.

Answer:

x = 15/27

Step-by-step explanation:

3(2x + 7x - 5)

Distribute the 3

6x + 21x - 15

Combine like terms

27x - 15 = 0

27x = 15

x = 15/27

Answer:

27x - 15 is your expression

Step-by-step explanation:

3 x 2x = 6x and 3 x 7x = 21x so 21x + 6x = 27x and 3 x 5 = 15 so 27x - 15 is your expression

Answer:

290[tex]mi^{2}[/tex]

Step-by-step explanation:

You can divide this shape in a variety of ways, but I am going to divide it into a rectangle and a square. First, to find the area of the square, multiple 6 by 5, and get 30[tex]mi^{2}[/tex]. Next, to find the area of the big rectangle, multiply 20 by 13 and get 260[tex]mi^{2}[/tex]. Finally, add 30 and 260 and get a final answer of 290[tex]mi^{2}[/tex].

Answer:

The probability is 1/2.

Step-by-step explanation:

There are 24 T-shirts in total and 12 is half of 24, the probability is 1/2.

I'm not sure about answer...

The probability of randomly selecting a red shirt is 50%.

Step-by-step explanation:

To figure this out, separate the total number of shirts into fractions based on the color. So for example, it would look something like this: Navy shirts are 4/24, Red shirts are 12/24, and White shirts are 8/24. The probability for each of the colors would be; Navy-16.666 percent, Red-50 percent, White-33.333 percent. Since we are only looking for the probability of selecting a Red shirt, the probability would be 50%.

Answer:

180°

Step-by-step explanation:

The measure of an inscribed angle (inscribed inside a circle) is half the measure of its inscribed arc.

m∡H = (1/2)(m arc GJI)

m∡J = (1/2)(m arc GHI)

m∡H + m∡J = (1/2)(m arc GJI + m arc GHI)

But those two arcs added together on the right side are the whole circle, so they add to 360°.

m∡H + m∡J = (1/2)360°

m∡H + m∡J = 180°

Answer:

  $74.67

Step-by-step explanation:

Let p represent the original price. Then the relation is ...

  $56 = p - 0.25×p

  $56 = 0.75p

  $56/0.75 = p ≈ $74.67

The original price was $74.67.
