Answer:
The number of student tickets sold was 105
Step-by-step explanation:
Let
x ----> the number of student tickets sold
y ----> the number of adult tickets sold
we know that
If total of 230 tickets are sold for $825
then
----> equation A
----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
using a graphing tool
The solution is the point (105,125)
see the attached figure
therefore
The number of student tickets sold was 105
Answer:
a = g/c - r/c + d/c
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:
When you multiply through by the LCD and solve the resulting quadratic equation, you get solutions x=2 and x=1. However when we try to check the solution x=2, it causes the first and last denominators to become 0, which is undefined. However x=1 checks.
Step-by-step explanation:
18)
It says the scale factor is 1:25000, so for every one part there is actually 25000. So for every centimeter, there is actually 25000 cm. See that we multiplied by 25000.
So for 6.8cm, multiply by 25000 to get 170000cm.
The real distance represented is 170000cm.
19) Just work out one step at a time using order of operations.
Do parentheses first. 7^2 = 49, and 3^3 is 3*3*3 which is 27.
Now you have [8(49 - 27) ]/ sqrt121.
Finish simplifying the parentheses. 49 - 27 is 22.
[8(22)] / sqrt121.
Now multiply 8 times 22, which is 176.
176 / sqrt 121
The square root of 121 is 11.
176/11.
= 16
