Gary knows that p = 2 1/2 is a solution to one of the following equations. which one has p = 2 1/2 as its solution?

p + 2 1/2 = 5 p - 2 1/2 = 5

2 + p = 2 1/2 4 - p = 2 1/2

Step-by-step explanation:

we can solve the equations and see which one has a solution of

the first equation is:

i will chanche for which is the same:

and clearing for p:

in this equation we gget that the solution  is

which is the solution we where looking for.

and also, when the p is cleared in the other equations, a different result is obtained from the one desired

So the answer is:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
