(5x+37)"<br> S<br> W<br> (3x-9)<br> Р<br> T<br> What is the value of x?
svp [43]

Step-by-step explanation:

well, the arcs WS and ST together are the full half-circle and therefore 180°.

that means

5x + 37 + 3x - 9 = 180

8x + 28 = 180

8x = 152

x = 19

3x + y - z= -6<br> 2x - y + 2z = 8<br> 4x + y - 3z = -21
Flauer [41]

Answer:

x=-1

y=4

z=7

Step-by-step explanation:

3x + y - z= -6(1)

2x - y + 2z = 8(2)

4x + y - 3z = -21(3)

(1)+(2): 5x+z=2(4)

(2)+(3): 6x-z=-13(5)

(4)+(5): 11x=-11

x=-1

so z=2-5x=7

y=-6-3x+z=4
