Answer:
The answer is B:subtract 1,add x,divide by 4
The other answer is D:add x,subtract 1,divide 4
Step-by-step explanation:
when you subtract 1 you isolate 3x so the equation looks like 3x=-x+3
the next step is to add x to both sides so you isolate the x to one side after doing that your equation should look like 4x=3,after this you divide both sides to the solution x=
The answer is also D because if you add x to both sides u isolate x to the left side so the equation will look like 1+4x=4 the next step will be to subtract one from each side and after doing this the equation should look like 4x=3 which should look familiar because its the same exact solution as B was so the answer to this choice is x=
With that evidence I can reasonably say that answer to the question is B,and D
Answer:
or
Step-by-step explanation:
Let S be the sum of the times for all winning team.
Given:
leg 1. 32 minutes 56 seconds.
leg 2. 42 minutes 28 seconds.
leg 3. 34 minutes 34 seconds.
leg 4. 39 minutes 2 seconds
We need to find the total time to run all four legs of the marathon.
Solution:
Sum of the times for all winning team.
Substitute running times for all legs.
Now, we write the minutes and seconds separately.
Therefore, Total time taken by all four legs or
