The 21 part repeats
it can be represented as 21/99
it's rational
3575747537543764666+6777777888888889999999990000000
0.3m=$4.41
just divide $4.41/0.3= m
m=14.7
The area of the shape is 230 cm.
First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.
2x+7=3x-7
x=14
Then, since 2x+7 and 12y+1 equals 180, put it together to find y:
(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12
So, x=14 and y=12. Your answer should be C!
