Solve for x. I NEED HELP ASAP!

Mathematics
1 answer:
galina1969 [7]3 years ago
6 0

Answer:

x = 105

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900, that is

2x + 690 = 900  ( subtract 690 from both sides )

2x = 210 ( divide both sides by 2 )

x = 105

  • Let x be the percentage of p.
  • Therefore,
  • m\% \:  \: of \:  \: n = x\% \:  \: of \:  \: p \\  =  >  \frac{mn}{100}  =  \frac{px}{100}  \\  =  > mn =  \frac{px}{100}  \times 100 \\  =  > mn = px \\  =  >  \frac{mn}{p}  = x

<u>Answer:</u>

<u>\frac{mn}{p}</u>

Hope you could get an idea from here.

Dorothy is using fabric to cover a photo album the width of the fabric is 5/8 of a yard the area of the fabric is 5/16 square ya
saul85 [17]

For this case we assume that the photo album is rectangular in shape and therefore the fabric too. By definition, the area of a rectangle is given by:

A = a * b

Where:

a: It is the length of the rectangle

b: It is the width of the rectangle

According to the problem data we have to:

b =\frac {5}{8} \yard\\A = \frac {5} {16} \ yards ^ 2

Substituting:

\frac {5} {16} = a * \frac {5} {8}

We clear "a":

a = \frac {\frac {5} {16}} {\frac {5} {8}}\\a = \frac {5 * 8} {16 * 5}\\a = \frac {8} {16}\\a = \frac {1} {2}

Thus, the length of the fabric is \frac {1} {2} yards.

ANswer:

The length of the fabric is\frac {1} {2} yards.
