2c=14 (move 5 to the other side by adding it to 9)
c=7 (divide by 2 to get c on its own)
Let's translate the expression step by step:
"Five less than..."
we will have to subtract five from something
"two times a number"
.
So, we have
"Five less than two times a number"
.
This "is sixty-nine", where "is" means "is equal to". So, the equation is

which is option B
Using cosine law,
d^2 = 65^2 + 35^2 - 2(65)(35)cos140
= 8935.5022
d = sqrt(8935.5022)
= 94.5 m
Angle = inverseCos(35sin40 / 94.5) = 76.23 degrees South of East
Answer:
it would simplify to 12/1 or just 12
Substitute <em>u</em> = <em>t</em> ³/2592 and d<em>u</em> = <em>t</em> ²/864 d<em>t</em>. Then

The probability that a 12 hour surgery is successful is <em>P</em> (12), so letting <em>T</em> = 12 gives
