Start by defining variables (things you don't know). Let's make:
t = number of true/false questions
m = number of multiple choice questions
Equation #1
total questions on the test (given to be 20) is then:
t + m = 20
Equation #2
Multiply the number of questions by the points it's worth to get the total points
3t + 11m = 100
Now, you can use substitution to combine the two equations.
t + m = 20
by subtracting m from both sides, equation 1# becomes..
t = 20 - m
substitute t for 20 - m in the second equation.
3(20 - m) + 11m = 100
Solve for m.
3(20 - m) + 11m = 100
60 - 3m + 11m = 100
8m = 100 - 60
8m = 40
m = 5
There are 5 multiple choice questions on the test.
Now use this to find t.
t + m = 20
t + 5 = 20
t = 20 - 5
t = 15
there are 15 true/false questions on the test.

Answer:
Option B- The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
Step-by-step explanation:
Given :
The function 
represents price charged per customer where x is the number of $5 increases they charge over a rate of $50 per person.
The function 
represents the number of customers expected for the day, where x is the number of $5 increases they charge over a rate of $50 per person.
To find : (p⋅c)(2) mean about the horse-drawn carriage tour company.
Solution :
(p.c) means we multiply the p(x) and c(x)
Substitute the value of x=2
The horse-drawn carriage tour company can expect to take in $5760.
The function represents price charged per customer.
For x=2
The charge per customer is $60.
Therefore, Option B is correct.
The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
Answer:
i believe its A
Step-by-step explanation:
Use the slope formula.
Y2 - Y1 / X2 - X1
(3,1) (6,-5)
-5 - 1 / 6 - 3
-6 / 3
slope = -2
