15% = 0.15
multiply the bill ( 42.00) by 0.15 for the amount of tip

the tip = $6.30
Answer:
-4/5 = x
Step-by-step explanation:
It would help to know which side is B, can you give a chart?
And I'm on my phone, I can't comment directly on the post, unless someone can tell me how.
A^2 = b^2 + c^2 -2bc * cos(A)
a^2 = 144 + 225 -360 * .5
a^2 = 189
a = 13.748
First, let's simplify these fractions so we can properly compare!
1/5 = 1/5
5/5= 1
5/1 = 5
Now, looking at our numbers we can conclude that 1/5, 5/5 and 5/1 are NOT equivalent to each other.
Hope this helps!
