Simplify:
2a/3x+3a/2x+5a/6x​

the answer is 10a+11x

Step-by-step explanation:

2a+3a+5a=10a

3x+2x+6x=11x

19a/6x

Step-by-step explanation:

find common denominator which is 6x  

so 2a/3x+3a/2x+5a/6x​ =4a/6x+9a/6x+5a/6x

which simplifies into 19a/6x

78.59 is the mean

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:
