2. 3m=300, m=100

3. yes

Step-by-step explanation:

2. this is 3m=300 because since each of the 3 drivers drove an equal amount, you would write 3m. Also, since the total is 300, you would write 3m=300. to solve, you divide 300 by 3 and you will get 100.

3. The answer is yes because if you substitute 7 for y, the equation would be 7=x+6. this equation has a solution. the solution is x=1

the difference between a number and 5 is -2.
