Step-by-step explanation:
50,000/250= 200 There are 200 seats in each section.
Answer:
Twice ; c = 2a ; a = c/2
Step-by-step explanation:
Since the drawing area has been gridded, accurate calculation could easily be performed ;
Rope A occupies 5 boxes
Rope C occupies 10 boxes
Hence,
10 boxes for C / 5 boxes for A
Therefore,
Rope C is Twice the length of Rope A.
If length of Rope A = a ; length of Rope C = c
Then, a multiplication equation for the length of Rope C equals ; c = 2a
Division equation :
a = c/ 2
To solve for the value of x, it is easiest by isolating "x" to one side of the equation. This method is shown below:
-2x - 13 = 8x + 7
Adding 2x to both sides:
-2x - 13 + 2x = 8x + 7 + 2x
-13 = 10x +7
Subtracting 7 from both sides:
-13 - 7 = 10x + 7 - 7
10x = -20
Dividing both sides by 10:
10x / 10 = -20 / 10
x = -2
