Answer:
you need to isolate t or time
you need to know distance between sun and earth and velocity of them in order to calculate how long it takes for light to travel from the Sun to Earth
Step-by-step explanation:
to find time you multiply t to both sides then you cancel t from where velocity is and you get velocity by itself
now you mulipy d to both side to get v over d and time by itself
A) d+q=20
0.1d+0.25q=4.40 Let's just read what this says: first, # of dimes (d) plus # of quarters (q) is 20.The second equation can be called the VALUE EQUATION; it says that one tenth of a dollar ($0.10) times the # of dimes is part of the total monetary value, and that one quarter of a dollar ($0.25) times the # of 'quarter' coins is the other part of this stash, and it totals $4.40. VOTE FOR A.
