Given:
Total number of tickets = 600
Cost of adult ticket = $6.00
Cost of student ticket = $4.00
Total sales = $2900.00
To find:
The number of tickets of each type.
Solution:
Let the number of adult tickets be x and number of student tickets be y.
According to the question,
...(i)
...(ii)
Multiply equation (i) by 4 and subtract the result from (ii),
Divide both sides of 2.
Put x=250 in (i).
Therefore, number of adult tickets is 250 and number of student tickets is 350.
Answer: It is not reasonable.
Step-by-step explanation: when subtracting a negative number from a positive number the answer is always going to be positive because two negatives make a plus. For example 3-(-5). The two negatives cancel each other out, so it’s 3+5=8
Note that the from
to 0, that is the left part, the function is the line y=1.
Similarly, from 0 (not included) to
, the function is y=-1.
Thus the function is given by the rule:
y=1, for x≤0,
y=-1, for x>0.
Remark: a horizontal line at height c, from the x-axis, is the graph of the function y=c.
Answer:
2(x+5)=2x-3
2x+10=2x-3
2x-2x= -3-10
0= -13
Step-by-step explanation:
A- price of adult's ticket
c- price of children's ticket
a+3c=20
a=c+2
c=a-2
a+3(a-2)=20
a+3a-6=20
4a=26
a=6.5
The cost of an adult's ticket is $6.50
