Answer:
See below.
Step-by-step explanation:
a.
x = cost of adult ticket
y = cost of student ticket
cost of adult ticket is twice the cost of a student ticket
x = 2y
number of adult tickets = 64
number of student tickets = 132
cost of all adult tickets = 64x
cost of all student tickets = 132y
cost of all adult and student tickets combined: 64x + 132y
cost of all adult and student tickets combined: 1040
This gives us the equation:
64x + 132y = 1040
b.
Use substitution to solve the system of equations. Since x = 2y, where you see x in the second equation, substitute it with 2y.
64(2y) + 132y = 1040
128y + 132y = 1040
260y = 1040
y = 1040/260
y = 4
x = 2y = 2(4) = 8
adult ticket: $8
student ticket: $4
The answer to this one is the 3rd one
Answer:
<em>-4/5,-1/2,-0.2,0.25</em>
Step-by-step explanation:
To order these, it would be best to convert them into decimals.
-4/5 is equal to -0.8
-1/2 is equal to -0.5
-0.8 is the least, because the further left on a number line, the less the number is.
-0.5 is next and then -0.2
Finally, 0.2 is the greatest
<em>-4/5,-1/2,-0.2,0.25</em>
<u>Hope this helps :-)</u>
