Answer:
The awnser would be B.
Step-by-step explanation:
If she needs to make 623$ Then she would have to make more than or equal to the number she needs. $8.22h ≥ $623 represents this because its greater than of equal to. :)
Solving a system of equations we will see that they sold 80 adult tickets.
<h3>how many adult tickets were sold?</h3>
To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:
- x = adult tickets sold.
- y = student tickets sold.
They sold 20 more adult tickets than student tickets, then:
x = y + 20
And they collected a total of $880, then:
x*$8 + y*$4 = $880
The the system of equations is:
x = y + 20
x*$8 + y*$4 = $880
Isolating y on the first equation we get:
y = x - 20
Replacing that on the other equation we get:
x*$8 + (x - 20)*$4 = $880
Now let's solve that for x.
x*$12 - $80 = $880
x*$12 = $880 + $80 = $960
x = $960/$12 = 80
They sold 80 adult tickets.

A. Yes
B. Because the three inside angles of both triangles would be identical.
C. Set up a ratio:
121/22 = AB/30
Solve for AB:
AB = (121 * 30) / 22
AB = 3630 / 22
AB = 165 ft.
Answer:
Side length of each booth is 8.35 ft approximately.
Step-by-step explanation:
There are 11 companies set up equal sized square booths in a row along one wall of a convention center.
Now, refer the diagram to answer the problem.
It is given area is 1200.
So, length x width =1200
(11x+24)(x+2)=1200
Multiply using FOIL method.
+22x+24x+48=1200
+46x+48-1200=0
+46x-1152=0
Solve using quadratic formula
x=
x=
x=
Simplify it
Simplify to get two values for x.
x=8.35; x=-12.67
Here negative does not work.
Side length of each booth is 8.35 ft.
