Answer:
Step-by-step explanation:
12x+2y=36
2y=36-12x
5x+36-12x=22
7x=14
x=2
2y=36-12(2)
2y=12
y=6
btw,next time, please do not include words like(failing ,exam,test,etc) in your question,otherwise, the question might be deleted.
Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4

Answer:
3.5 cm
Step-by-step explanation:
In the picture attached, circle M is shown.
From the picture, minor arc JH measures 25°.
The length of the circle is π*Diameter = π*16 = 50.26 cm. This length is proportional to 360°. To find the length of minor arc JH, we have to use the next proportion:
50.26 cm / x cm = 360° / 25°
x = 50.26*25/360
x = 3.5 cm
