Solve this equation: 2/3(h)-156=3(13/24)

1) 2/3h -156 = 3(13/24)⇒2/3h-156 = 39/24

2/3 h = 39/24+156

2/3h = 39+3744/24

the m.c.m is 24  , then you must divide the denominator by 24 and multiply the result for numerator to obtain a lineal equation, it is in both terms of the equation

8*(2)h =39+3744

16h = 3783

h =3783/16

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:
