Answer:
Step-by-step explanation:
Let c represent the number of child tickets sold. Then 2c-14 is the number of adult tickets sold, and total revenue is ...
5c +8(2c-14) = 728
21c -112 = 728 . . . . . . simplify
21c = 840 . . . . . . . . . . add 112
c = 40 . . . . . . . . . . . . . divide by 21
2c-14 = 66 . . . . . . . . . number of adult tickets sold
66 adult tickets and 40 child tickets were sold.
Answer:
True
Step-by-step explanation:
we know that
The opposite sides of a parallelogram are parallel and the length of their sides is equal.
step 1
<em>Find the slope of each side</em>
we know that
If two lines are parallel then their slopes are the same
The formula to calculate the slope between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
compare
m1=m2
therefore
both lines are parallel
step 2
Find the distance
the formula to calculate the distance between two points is equal to
we have
<em>one side</em>
Substitute the values
<em>opposite side</em>
Substitute the values
Compare
d1=d2
Both sides have the same length
so
1) Both lines are parallel
2) Both sides have the same length
therefore
The statement is True
