79 is 4 below 83 so her next grade needs to be 4 above in order to get an average of 83. The answer is 87.
Let the number of miles be x.
Then, x miles cost 0.6x.
The initial fixed fee is $5, and the toll is $5.
cost = initial fixed fee + cost per mile + toll
46 = 5 + 0.6x + 5
0.6x + 10 = 46
0.6x = 36
x = 36/0.6
x = 60
You can travel 60 miles.
Just get only one of the placeholder on one side by itself
and do the same thing to both sides so it stays equal
3x+7=5x-21
add 21 to both sides
3x+28=5x
subtract 3x from obht sides
28=2x
sivide both sides by 2
14=x
Answer:
A. 30
Step-by-step explanation:
sin theta = opposite side / hypotenuse
sin B = 8/16
sin B = 1/2
Take the arcsin of each side
arcsin sin(B) = arcsin (1/2)
B = arcsin (1/2)
B = 30
