Simplify

OlgaM077 [116]

Answer:

see below

Step-by-step explanation:

$\frac{x-1}{x^2-3x+2}+ \frac{x-2}{x^2-5x+6} +\frac{x-5}{x^2-8x+15}$

we need to simplify that

$x^2-3x+2=(x-1)(x-2)\\\\x^2-5x+6=(x-2)(x-3)\\\\x^2-8x+15=(x-3)(x-5)$

so we can continue

$\frac{x-1}{(x-1)(x-2)}=\frac{1}{x-2}\\\\\frac{x-2}{(x-2)(x-3)} =\frac{1}{x-3}\\\\\frac{x-5}{(x-3)(x-5)} =\frac{1}{x-3}$

and we can put all together

$\frac{1}{x-2}+ \frac{1}{x-3}+ \frac{1}{x-3}\\\\\frac{1}{x-2} +\frac{2}{x-3}\\\\\frac{x-3}{(x-3)(x-2)}+ \frac{2(x-2)}{(x-2)(x-3)} \\\\\frac{x-3+2x-4}{(x-3)(x-2)}\\\\\frac{3x-7}{x^2-5x+6}$

Help me solve # 15 & 16

makkiz [27]

Answer:

15) $C=frac{5}{9}(F-32)$

16) 12 hours

Step-by-step explanation:

15) $F=\frac{9}{5}C+32 \\F-32 = \frac{9}{5}C\\\frac{5}{9}(F-32)=C$

16) If Jim drove 168 mi in 4 hours, this means it takes him

$\frac{4 hours }{168 mi}$

this many hours to drive 1 mile. So if we multiply this by 504 mi:

$\frac{4 hours }{168 mi} 504 mi = 4 \cdot 3 hours = 12 hours$
