What is the least common multiple of 60,50,
and 80 ?

Step-by-step explanation:

1200

Factorize of the above numbers :

   60 = 22 • 3 • 5

   80 = 24 • 5

   50 = 2 • 52

1200 is Correct

Here is the explanation:

60 = 22 * 3 * 5  

80 = 24 * 5  

50 = 2 * 52

27

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
