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:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24
