Step-by-step explanation:
<u>Equation Solving</u>
We are given the equation:

It's required to solve the equation for D. All letters must preserve their capitalization.
We must isolate the letter D by removing from the left side all the terms and coefficients that surround it.
Adding 7:

Dividing by f:

You first have to equalize all of the denominator
2/3 will be equal to : 8/12
Total of their practice time would be :
11/12 + 8/12 = 19/12 hours

Answer:
distance = 585600 m
Step-by-step explanation:
change 2 hours 20 minutes to seconds
2 hrs * 60 minutes/1hr * 60 sec/min = 7200 sec
20 minutes * 60 sec/min = 120 sec
2 hr 20 min = 7320 seconds
distance = rate * time
distance = 80 m/s * 7320 s = 585600 m
Addition is the first step in solving the equation. Here is how to solve this problem:
x/3 - 3 = 11
+ 3 + 3
