All together it equals (of the number of hours he does in a week)
45 because 6 plus 9 is 15 and 15 multipled by 3 is 45 makes sense becuase .. 6 +3 is 9 and 9 +9 is 18 2 weeks equals 14 days 18 subtracted by 14 equals 2 which 45 subtracted by 2 is 43 and that's the esact number of hours he works 43 in a week.
X=number of senior tickets
y=number of student tickets
1st day
7x+1y=101
2nd day
7x+12y=134
easy, we can eliminate the x's
multiply first equation by -1
-7x-1y=-101
<u>7x+12y=134 +</u>
0x+11y=33
11y=33
divide by 11 both sides
y=3
sub back
7x+y=101
7x+3=101
minus 3 both sides
7x=98
divide both sides by 7
x=14
senior tickets cost $14
student tickets cost $3
that sounds unfair
Answer:
1st and 2nd statements are true.
Step-by-step explanation:
We are asked to choose the correct statements that can prove that quadrilateral DEFG is a parallelogram.
We will use parallelogram properties to answer this problem.
Since we know that a parallelogram has two sets of opposite angles congruent, therefore, 1st option is a correct choice.
Since a parallelogram has one set of opposite sides that are both congruent and parallel, therefore, second statement is true.
Since the consecutive angles of a parallelogram are supplementary, therefore, 3rd statement is not true.
Since the diagonals of parallelogram bisect each other, therefore, 4th statement is not true.
