Answer: John had 72 pins originally.
Step-by-step explanation:
Let x represent the total number of pins that John had originally.
John divided his souvenir hat pins into two piles. The two piles had an equal number of pins. This means that each pile has x/2 pins.
He gave his brother one-half of one-third of one pile. This means that the number of pins that he gave his brother is
1/2 × 1/3 × x/2 = x/12 pins
The total amount left is
x/2 + (x/2 - x/12) = x/2 + 5x/12 = 11x/12
John had 66 pins left. Therefore
11x/12 = 66
11x = 66 × 12 = 792
x = 792/11 = 72

Hello there, and thank you for posting your question here on brainly.
The diameter of a circle is how long it is from the left side of the circle to the right side.
The radius of a circle is the length of either the left or the right side to the middle.
So, the radius is half of a radius.
You can divide the known diameter by 2 to get your answer.
Its diameter is 25.
Divide 25 by 2.
25 / 2 = 12.5
Its radius is 12.5 in.
That would be answer choice A.
Hope this helped!! ☺♥
The answer is C -5/16 is -0.3 which means -5/16 cant be greater than or less than -0.3 so A and D are wrong and -2/3 is less than -5/16 which leaves us with C!
