Michaela has up to $20 to spend on bottled water and orange juice for a group hike. It cost $2
for each bottle of water and $4 for each bottle of orange juice.
a) Write an inequality statement for this situation.

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

-3(b-8)-5=9(b+2)+1

distribute

-3b+24-5=9b+18+1

add/ subtract

-3b+20=9b+19

20-19= 1

-3b+1=9b

9b+3b= 12b

1=12b

1 divided by 12 = 1/12

answer: 1/12 = b

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer
