Add the frequency’s together:

84 + 36 + 72 + 84 + 204 = 480

Divide each frequency by the total then multiply by 360 degrees:

A = 84/480 x 360 = 63 degrees

B = 36/480 x 360 = 27 degrees

C = 72/480 x 360 = 54 degrees

D = 84/480 x 360 = 63 degrees

E = 204/480 x 360 = 153 degrees

5. What is the measurement of each angle?

Alexxandr [17]

Answer:

x=14

Step-by-step explanation:

The sum of a interior angle is 180°

(7x-11)+(2x-3)+(5x-2)°=180°

7x+2x+5x=180+11+3+2

14x/14=196/14

x= 14

Hope this answers your question!! :)

Answer: D. (-6,2)

Step-by-step explanation:

y = x + 8

2x + y = -10

2x + x +8 = -10

x = -6

y = -6 + 8 ( plug in x (-6) )

y = 2

( x, y) = ( -6, 2)

The cost of 7 chairs and 2 tables is equal.If the cost of 6 chairs and 5 tables is 10575, find the cost of 12 chairs.

Igoryamba

Answer:

5400

Step-by-step explanation:

Let x represent the cost of a chair and y represent the cost of a table. We can use this to set up a system of equations:

7x=2y

6x+5y=10575

We can solve this system using substitution.

Start by rewriting the first equation in terms of x.

$7x=2y\\\text{Divide both sides by 7}\\x=\frac{2}{7}y$

Substitute this into the second equation:

$6(\frac{2}{7}y)+5y=10575\\\frac{12}{7}y+5y+10575\\\frac{12}{7}y+\frac{35}{7}y=10575\\\frac{47}{7}y=10575$

Multiply both sides by 7

$47y=74025$

Divide both sides by 47

$y=1575$

This means...

$7x=2(1575)\\7x=3150$

Divide both sides by 7

$x=450$

One chair costs 450. Now, multiply this number by 12 to find the cost of 12 chairs.

$450*12=5400$

12 chairs cost 5400.
