Answer: The test contains 10 three-point questions and 14 five-point questions. 
Step-by-step explanation:
Let x represent the number of 3-point questions.
Let y represent the number of 5-point questions.
The maths test consists of 24 questions. This means that 
x + y = 24
Each question is worth either 3 points or 5 and the test is worth 100 points. This means that 
3x + 5y = 100 - - - - - - - - - - -1
Substituting x = 24 - y into equation 1, it becomes
3(24 - y) + 5y = 100
72 - 3y + 5y = 100
- 3y + 5y = 100 - 72
2y = 28
y = 28/2 = 14
Substituting y = 14 into x = 24 - y , it becomes
x = 24 - 14 = 10
 
        
             
        
        
        
Answer:
v = 16
Step-by-step explanation:
p = 8/v and p = 1/2.  Equating these two, we get 8/v = 1/2.
Inverting both sides, we get v/8 = 2.
Find the vaue of v by multiplying both sides by 8:  v = 16
 
        
             
        
        
        
The answer would be 7x+ 17
