Morgarella [4.7K]

Answer:

Step-by-step explanation:

The sum of the internal angles of a polygon is

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

here n = 5, hence

sum = 180° × 3 = 540°

Each exterior angle plus interior angle = 180°

Subtract each exterior angle from 180 for corresponding interior angle.

180 - 59 = 121, 180 - 77 = 103, 180 - 66 = 114, 180 - 62 = 118

Sum the 4 interior angles and subtract from 540 for 5 th interior angle

5 th = 540° - (121 + 103 + 114 + 118)° = 540° - 456° = 84°

The 5 th interior angle and 12x sum to 180 ( same reason as above )

Hence

12x + 84 = 180 ( subtract 84 from both sides )

12x = 96 ( divide both sides by 12 )

x = 8

Add - 3/x + 7y/x . -4y/2x -3 + 7y/x - 10y/x -3 + 7y/2x

yanalaym [24]

Answer:

$-\frac{3}{x} + \frac{7y}{x} = \frac{-3+ 7y}{x}$

Step-by-step explanation:

Given

$-\frac{3}{x} , \frac{7y}{x}$

Required

Add

The statement can be interpreted as:

$-\frac{3}{x} + \frac{7y}{x}$

Take LCM

$-\frac{3}{x} + \frac{7y}{x} = \frac{-3+ 7y}{x}$

Emi buys 14 balloons. Three are red, four are white, and the rest are blue. Hat is the ratio of blue balloons to the total numbe

Deffense [45]

Answer:

The ratio of blue balloons to the total number of balloons is 1:2.

Step-by-step explanation:

Given:

Total number of balloons = 14

Number of red balloons = 3

number of white balloons = 4

Number of the blue balloons are the rest remaining.

We need to find the the ratio of blue balloons to the total number of balloons.

Solution:

First we will find the number of blue balloons.

Now we know that;

Number of the blue balloons can be calculated by Total number of balloons minus sum of Number of red balloons and number of white balloons.

framing in equation form we get;

Number of the blue balloons = $14-(3+4) =14 -7 =7$

Now to find the ratio of blue balloons to the total number of balloons we will divide Number of the blue balloons from Total number of balloons.

framing in equation form we get;

Ratio = $\frac{7}{14} = \frac{7\times1}{7\times2}= \frac{1}{2}$

Hence the ratio of blue balloons to the total number of balloons is 1:2.

Masja [62]

I am not sure about this question because im in middle school but still tried it so....
300%/100=3
$6.00/3=$2.00

Before the markup the cotton candy cost $2.00
