The length of each piece is 29.53 cm if rope is cut into 10 pieces
The length of each piece is 2.953 cm if rope is cut into 10^2 pieces
The quotient are same only the placement of decimal is changed due to the divisor. Dividing by a larger number makes the quotient smaller
Step-by-step explanation:
Given
Length of rope = l = 293.5 cm
When the rope is divided in 10^1 pieces
Dividing the rope in 10^2 equal pieces
Hence,
The length of each piece is 29.53 cm if rope is cut into 10 pieces
The length of each piece is 2.953 cm if rope is cut into 10^2 pieces
The quotient are same only the placement of decimal is changed due to the divisor. Dividing by a larger number makes the quotient smaller

Answer:
the right answer is:
- (A)
Step-by-step explanation:
You take the equations that the exercise give you:
- x + y = 4
- x - y = a
Now you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
- x - y = a
- -y = a - x
3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
- x + y = 4
- x + (x - a) = 4
- x + x - a = 4
Add the x variables:
- 2x - a = 4
- 2x = 4 + a
- x = (4 + a) / 2
That's the answer of the exercise, but you can represent this in this form:
- x = (4 + a) / 2 ↔
- x = (4 + a) / 2 ↔
By this reason, the right answer is <u> </u><u>.</u>
