Miss sim traveled 42 countries in 60 days at this rate how many countries would you travel in 40 days

First, let's make an attempt to find the unit rate:

42/60 = 14/20

14/20 = 7/10

7/10 is close enough, because 40 is a multiple of 10.

Because 40/10 = 4, we'll have to multiply both sides of the fraction by 10:

7*4/10*4

28/40

Miss Sim will travel 28 countries in 40 days

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
