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
Answer:
b = -30
Step-by-step explanation:
-b/5 - 27 = -21
~Add 27 to both sides
-1/5b = 6
~Multiply -5 to both sides
b = -30
Best of Luck!
Answer:
192
Step-by-step explanation:
you really should do your own test
A = lwh
A = 6 x 4 x 5 + 3
A = 6 x 4 x 8
A = 192
For example, 3/5.
3/5 = 0.6.
1/2 = 0.5
2/3 = 0.6666
0.5 -- 0.6 -- 0.66666666
