Based on the information given, the speed is 20 miles per hour.

From the information given, the winner of the local triathlon swam 0.5 miles, biked 15 miles and ran 2.5 miles and he finished the race in 54 minutes.

Note that 54 minutes = 0.9 hour.

The speed will be:

= (0.5 + 15 + 2.5) / 0.9

= 18/0.9

= 20 miles per hour.

9 minus 3 divided by 1/3 plus 1 (solve using B.O.D.M.A.S. procedure)
Citrus2011 [14]
9 - 3 ÷ 1/3 + 1
BODMAS says that the first thing we do in this is the division (D), so 3 ÷ 1/3 = 9
9 - 9 + 1
Now we do the addition, 9 + 1 = 10
9 - 10 = -1
So your final answer is -1, I hope this helps!

Answer:15*(x-3)^2*(x-5)

Step-by-step explanation:

\dfrac{x^2-y^2}{x^2-8x+15}\ and\ \dfrac{y^2}{15(x^2-6x+9)} \\\\\\x^2-8x+15=x^2-3x-5x+15=x(x-3)-5(x-3)=(x-3)(x-5)\\\\15(x^2-6x+9)=15*(x-3)^2\\\\LCM (x^2-8x+15,15(x^2-6x+9)\\\\=LCM((x-3)(x-5),15(x-3)^2)\\\\\boxed{=15*(x-3)^2*(x-5)}\\
