To solve part a, do the following.
49.84-44.50=<span>5.34
5.34/44.50=x/100
after solving the proportion, x would be equal to 12.
To solve part b, do the following.
50+12=62
</span>To solve part c, do the following.
The amount of the tip is:
x/<span>57.50=62/100
which is </span><span>35.65
The total bill is:
35.65+</span>57.50=<span>93.15</span>
F = 1.8C + 32
F = 1.8(100) + 32
F = 180 + 32
F = 212 degrees
(3x+4) (2x-6)
6x-18x+4x-24
6x^{2} -14-24
