Answer:

27

Step-by-step explanation:

total = 360°

2x + 4x + 56 + 57 + 85 = 360

6x + 198 = 360

6x = 360 - 198

6x =  162

x = 162/6

x = 27

8 1/4 divied by d = 2/11 what is d
Luda [366]

Answer:

d = 363/8

Step-by-step explanation:

Let's write this as a fraction:

   8 1/4          2

------------- = -------

      d            11

One way in which this could be approached would be to interchange 'd' and '2:'

   8 1/4          d                   33             d

------------- = -------      or    -------- =  ---------

      2            11                   4(2)          11

           

Multiplying both sides by 11 isolates d:

33(11)                     363

-------- = d, or d = ----------

   8                           8

Hamid published a book of poems. He sold 35 copies in the first week for $10 per copy. He wanted to increase the price of
Natalija [7]

After reading through the story problem, I ended up with this equation:

(35-2)(x+.5) =?

or

(35-2)(10+.5)=?

Explanation:

He sells 35 books for usual weeks. Since he is selling his books at $.50 more his average number of copies decreased by 2.

35-2 = 33

Next, we know that he adds $.50 for his price for each copy. If the price is $10 per copy than it looks like this:

$10+$.50= 10+.5

or if the price is not $10 it will be

$x+$.5= x+.5

Literally 50 points for whoever can answer this
Liula [17]

Answer:

  • 92°

Step-by-step explanation:

<u>Sum of internal angles of a regular polygon is:</u>

  • S = 180(n - 2)

<u>We have here 5-sided polygon:</u>

  • S = 180*(5 - 2) = 180°*3 = 540°

<u>Now sum the given angles measures and solve for x:</u>

  • 3x + 1 + 2x + 15 + 3x - 10 + 3x - 8 + 5x - 2 = 540
  • 16x - 4 = 540
  • 16x = 544
  • x = 544/16
  • x = 34°

<u>Find the measure of angle R:</u>

  • m∠R = 3x - 10 = 3*34 - 10 = 102 - 10 = 92
  • m∠R = 92°
