Answer:
75% of the original paper’s size.
Step-by-step explanation:
Let’s say that the original size was 10 inches.
You then increase it by 50%. It is now 15 inches.
Now, you decrease it by 50%. 50% of 15 is 7.5. So, the paper is now 7.5 inches.
7.5 inches is 75% of the original paper size.

Radius = diameter/2 = 8/2 = 4m
Area of a circle = pi x r^2 = pi x 4^2 = 16pi m^2 ( exact area) or 50.27 m^2
Circumference = pi x diameter = 8pi m ( exact) or 25.12 m
Answer: The answer is x = 65 - 60y.
Step-by-step explanation: Given that Miguel is the grandfather of Raul and Paula is Raul's sister.
Now, let 'x' years be the age of Raul and 'y' years be the age of Raul's sister (Paula).
Also, given is the following information -
Raul's age = Grandfather's age - 60 × sister's age.
Since the age of Miguel, Raul's grandfather is 65 years, so we can write the following equation to find Paula's age
Thus, we can find Paula's age (y) using the equation
where 'x' is the age of Raul.
<em>multiply both sides by 5 </em> 3(15k+10)=5(12k-9)
<em>get rid of the brackets</em> 45k+30=60k-45
<em>take away 45k to both sides</em> 30=15k-45
<em>plus 45 to both sides</em> 75=15k
<em>divide both by 15</em> k=5
