Answer:
8x = 136
Where: x = 17
Step-by-step explanation:
Joshua is writing a novel. He wrote the same number of pages each day for a 8 days. At the end of 8 days he had 136 pages complete. Write an equation relating x, the number of days, to y, the total pages.
Let the number of pages read per day = x
Hence, the number of pages after 8 days = 8 × x = 8x
Total number of pages = y= 136
Therefore:an equation relating x, the number of days, to y, the total pages.
= 136 = 8x
Solving for x
136/8 = x
x = 17
 
        
             
        
        
        
Answer:
2y + 2z
Step-by-step explanation:
-x + 2z + x + 2y
= (-1 + 1)x + 2y + 2z
= 2y + 2z

Step-by-step explanation:



 
        
             
        
        
        
3y^-4 × (2y^-4) = 6y^-8
 = 6/1/y^8
 = 6/y^8
.................................................
1) When x^1 multiply with x^2, 1 will add to 2 and become 3 
= x^3
2) y^-1 = 1/y 
 3^-2 = 1/3^2 = 1/9
 5^-2 = 1/5^2 = 1/25
