Answer:
a. A. 49m B 30.5 m
Step-by-step explanation:
If I have understood the question correctly:
Ball A:
After each second the total distance travelled increases by 5 meters.
Ball A: after 10 seconds it has rolled 4 + (10-1) * 5 = 49m
Ball B: after 10 seconds it has rolled 3.5 + (10-1)* 3 = 30.5 m.
If you change 36 2/5 into a decimal, it would be 36.4. Multiply 36.4 by 3 to get 109.2, or 109 1/5. You can check your answer by dividing 109.2 by 3. You should get 36.4, or 36 2/5.
Will got 12 and John got 24.
You would set the equation as:
36=n+2n
Combine like terms
36=3n
Divide 3 from both sides
12=n
If you want to check it
12+2(12)=36
12+24=36
36=36
