Find the lcd for the following fractions:
(4/15x^3), (5/12x^2). answers: 25^3, 60x^3, 25x^5, 60x^5

60x^3

Step-by-step explanation:

Given:

4/15x^3 and 5/12x^2

finding LCM of denominators (15x^3,12x^2)

for variable x, as x^3 is the heighest power so we'll keep x^3

now for the numeric part

15= 3*5

12=3*4

common factor is 3, so

3*4*5 =60

hence LCD= 60x^3!

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:
