Find the solution to the systems of equation 3x-2y=-9 4x+3y22

Mathematics

eimsori [14]3 years ago

Answer:

x = 1 and y = 6

Step-by-step explanation:

3x - 2y = -9   ........................... eqn 1

4x + 3y = 22 ........................... eqn 2

to eleminate y, multiply eqn 1 by 3 and eqn 2 by 2

(3x - 2y = -9) × 3

(4x + 3y = 22) × 2

9x - 6y = -27  ........................... eqn 3

8x + 6y = 44  ........................... eqn 4

Add eqn 3 and 4 together and we get

17x = 17

x = 17/17

x = 1

To get y, substitute 1 for x in any of the eqns

taking eqn 4

8(1) + 6y = 44

8 + 6y = 44

6y = 44 - 8

6y = 36

y = 36/6

y = 6

GalinKa [24]

Answer:

two dice are thrown, so S = {(1,1); (1,2); (1,3); ...;(6,5); (6,6)} ---> 36

the sum is 2, 4, 6

sum = 2 --> (1,1) ---> 1

       = 4 --> (1,3); (2;2); (3,1) ---> 3

       = 6 --> (1,5); (2,4); (3,3); (4;2); (5,1) ---> 5

⇒ \frac{1 + 3+ 5}{36} = 9/36 = 1/4

The sum of all interior angles in a polygon is
180(n - 2), where n = the number of sides in the polygon.

now, notice this figure above, it has 5 sides, namely is a PENTAgon, so the sum of all its interior angles is 180( 5 - 2), or 540, therefore

\bf (4x)~+~(3x+15)~~+~~(4x-25)~~+~~(3x+25)~~+~~(2x-3)=540
\\\\\\
16x+12=540\implies 16x=528\implies x=\cfrac{528}{16}\implies x=33
