Explain how to solve the equatuon 312.50= a + 0.25a to find the value of a.

a = 250  Is Your Answer! (:

Step-by-step explanation:

Let's solve your equation step-by-step.

312.5=a+0.25a

Step 1: Simplify both sides of the equation.

312.5=a+0.25a

312.5=(a+0.25a)(Combine Like Terms)

312.5=1.25a

312.5=1.25a

Step 2: Flip the equation.

1.25a=312.5

Step 3: Divide both sides by 1.25.

1.25a / 1.25 = 312.5 / 1.25 =

A = 250 Hope This Helped!!! (:

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

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:
