Answer:
Formula for nth term in Arithmetic sequences is:

where a is the first term, d is the common difference and n is the number of terms.
As per the statement:
The rule for the pattern is add 4.
As the first term in line says the first term i,e 7

common difference(d)= 7
As the Jenna number is 8th in line.
Series we get;
7, 11, .........
We have to find the 8th term.
n = 8, a = 7 and d = 4
Using above formula:

Therefore, 35 number should Jenna say.
 
        
                    
             
        
        
        
Answer:
h = -144
you multiply 24 and -6 to get -144. 
 
        
                    
             
        
        
        
Answer:x + y = 54
x - y = 10 
Add them to get: 2x = 64
x = 32 
 
and plugging in x = 32 to either equation: y = 22 
Ans: the numbers are 22 and 32

Answer:
2/5
Step-by-step explanation:
5x+6y=11
as we have to find x coordinate
while y coordinate 3/2 is already given in question
so only put value of y coordinate in given equation to get x coordinate value
5x+6y=11
5x+6*(3/2)=11
5x+3*3=11
5x+9=11
5x=11-9
5x=2
x=2/5
