Answer:
-4,7
Step-by-step explanation:
add both to get y=7
then sub y in 2 to get 8x+42=10
8x=-32
x=-4
Answer: 7 is 1/8, 8 is 2/8 or 1/4
Step-by-step explanation:
There are 2pi radians in circle
so
circumference times arcinradians/2pi=areclength
c=2pir
c=2pi25
c=50pi
arc in radians=7pi/5
c times arcrad/2pi=
50pi times (7pi/5)/2pi=
50pi times 7/10=
35pi
it is 35pi cm or aprox 109.95574287564276334619251841478 cm
