The mid point is 15 because it is in the middle of 10 and 20
17x + 16x + 12x =180
45x = 180
x = 4
Largest angle = 17*4 = 68 degrees
That would be the number of permutations of 3 from 10.
= 10P3 = 10! / 7! = 10*9*8 = 720
I believe the correct answer from the choices listed above is the last option. THe missing step of her solution would be the statement "<span>Divide both sides of the equation by 10.4." Hope this answers the question. Have a nice day.</span>
Since z is inversely proportional to x, when x increases by a factor of 26/16, z will be multiplied by the inverse of that factor: 16/26
