Answer:

x,y = 13/3, -10/3

Step-by-step explanation:

8x+8y=8

8x+2y=28  Subtract eq1 by eq 2

6y=-20

y=-20/6 y = -10/3

8x - 80/3=8

8x=34 2/3

x=4 1/3

x=13/3

Answer:

x = 13/3 y = 10/3

Step-by-step explanation:

8x+8y = 8

8x + 2y = 28

y = 14 - 4x make y = 1 by dividing all by 2

8x + 8 ( 14- 4x ) = 8 substitute

8x + 112 - 32x = 8

-24x = -104

x = 13/3

y = -10/3

In the given figure, find ∠PQS, if∠PQR = 5x + 25 and∠SQR = 2x + 10.
kramer

Answer:

∠PQS= 3(x +5)

Step-by-step explanation:

∠PQR = 5x + 25

∠SQR+∠PQS= 5x+25

∠PQS = ∠PQR-∠SQR

∠PQS= (5x + 25 )-(2x + 10)

∠PQS = 5x+25 -2x-10

∠PQS= 3x +15

∠PQS= 3(x +5)
