Solve
1) 10x-2=xdivide by 5
2) 7 divided by -3 = 14 divide 4

Step-by-step explanation:

1) 10x-2=x/5

50x-10=x

50-x=10

49x=10

x=10/49

2)7/-3=14/4

=14/4 multiplied -3/7

=14 multiply -3/4 multiply 7

=42/28=3/2

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
