The product of p and 9 mean 9*p so 9p so the 3rd choice is right sure 
        
             
        
        
        
The weight of the new student is 27 kg.
Average weight
= total weight ÷total number of students
<h3>
1) Define variables</h3>
Let the total weight of the 35 students be y kg and the weight of the new student be x kg.
<h3>2) Find the total weight of the 35 students</h3>
<u> </u>
</u>
y= 35(45)
y= 1575 kg
<h3>3) Write an expression for average weight of students after the addition of the new student</h3>
New total number of students 
= 35 +1
= 36
Total weight
= total weight of 35 students +weight of new students
= y +x

<h3>4) Substitute the value of y</h3>

<h3>5) Solve for x</h3>
36(44.5)= 1575 +x
1602= x +1575
<em>Subtract 1575 from both sides:</em>
x= 1602 -1575
x= 27
Thus, the weight of the new student is 27 kg.
 
        
             
        
        
        
Answer:
a=7 b=24 c=25
Step-by-step explanation:
Leg a=7 
Leg b=24
According to Pythagorean theorem: a^2+b^2=c^2
49+576=c^2
C^2=625
c=25
 
        
                    
             
        
        
        
The given equation is  
 
We need to solve the equation for q.
<u>Value of q:</u>
The value of q can be determined by solving the equation  for q.
 for q.
Thus, subtracting both sides of the equation by r, we get;

Now, dividing both sides of the equation by b, we have;

Simplifying the terms, we get;

Therefore, the value of q is 
Hence, Option B is the correct answer.
