Answer:

x=36

Step-by-step explanation:

First rewrite equation then multiply each side by 36. 9x-36=4x+144.

then move the variable 9x-4x+36=144. Next subtract 9x and 4x ...5x=144+36.... 5x=180. Lastly you divide 180÷5 this your answer x=36

Pleaseee help me with this!!! ASAP
Artemon [7]

Answer:

108° or Red

Step-by-step explanation:

This looks closest to a 108° angle.

108 - 7 = 101

101 ÷ 5 = 23

<em>x</em> = 23

Do the simple math for the rest of the angles...

Here is the math from where that leaves you...

127° (<em>b</em>) + 90° (<em>d</em>) + 136° (<em>e</em>) + 79° (<em>a</em>) + 108° (<em>c</em>) = 540°

P.S.

Rectangle answer must be 360° because 90° × 4 = 360°

Any additional vertices equals another 180° to the final number.

The length of a rectangle is increased by 10 percent the width of a rectangle is increased by 5 find the percentage increased in
aalyn [17]

Answer: The percentage increase in perimeter is 7%.

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(length + width)

The original length of the rectangle is 20 and the original width is 30. The original perimeter of the rectangle would be

Perimeter = 2(20 + 30) = 100

The length of the rectangle is increased by 10 percent. It means that the new length would be

20 + (0.1 × 20) = 22

The width of the rectangle is increased by 5 percent. It means that the new width would be

30 + (0.05 × 30) = 31.5

The new perimeter of the rectangle would be

Perimeter = 2(22 + 31.5) = 107

The increase in perimeter is

107 - 100 = 7

The percentage increase in perimeter is

7/100 × 100 = 7%
