Answer:

Step-by-step explanation:

5x=y+6   --------- equ 1

2x-3y=4  -------- equ 2

5x - 6 = y

y = 5x - 6

substitute in equ 2

2x-3(5x - 6) =4

2x - 3*5x + 3*6 = 4

2x - 15x + 18 = 4

- 13x = 4 - 18

-13x = -14

x = -14/-13

x = 14/13

substitute  in equ 1

5*14/13 = y+6  

70/13 - 6 = y

y =  ( 70 - 78)/13

y = -8/13

Answer:

<h2>✓6 divided by 5 is 1.2, so 1.2 radians.</h2>

Step-by-step explanation:

<h3 /><h3>The circumference of the circle of 5 cm radius equal 2(pi)r= (2*22*5)/7=31.42857143cm and this =2(pi) radias.</h3>

<h3>So a 6cm are of the same circle will subtend(6/ 31.42857143)*2(pi) radians= 1.2 radians at the center of the cercle.</h3>

PLEASE HELP!!!! IN NEED OF IT
prisoha [69]

Answer:

Below in bold.

Step-by-step explanation:

This is a regular polygon so all sides are congruent, therefore:

The perimeter of the polygon = 6*34 = 204 units.

We can divide the polygon into 6 conguent triangle with height 30 and base 34.

So area of 1 triangle = 1/2*34*30 = 510.

So area of the polygon = 6 * 510 = 3060 unit^2.

Perimeter of the polygon = 6*34 = 204 units.

Someone pls help me with this.
Assoli18 [71]

Answer: m∠D = 65°

Step-by-step explanation:

The best solve method for problems like this is say the sum of the angle values equals 360.

2x-15+2x-15+x+x = 360

Then from here you just simplify.

4x+2x-30 = 360

6x = 390

x = 65

So the measure of Angle D equals 65 degrees.
