Ms. sims traveled to 42 countries in 60 days. at this rate, how many countries
would she travel to in 40 days?

28

Step-by-step explanation:

The first step to solve this problem is to figure out how many countries per day ms. Sims travels. Do this by dividing 42 by 60. If the division sign is a “per” symbol she would travel 42 every 60 days.

42/60 is 0.7

So she travels 0.7 countries per day.

Multiplied by 40 days (40 times 0.7) is 28. 28 countries per 40 days

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
