9 / 60 = 0.15
To the nearest tenth is 0.2 miles per minute
3x - y + z = 5 . . . (1)
x + 3y + 3z = -6 . . . (2)
x + 4y - 2z = 12 . . . (3)
From (2), x = -6 - 3y - 3z . . . (4)
Substituting for x in (1) and (3) gives
3(-6 - 3y - 3z) - y + z = 5 => -18 - 9y - 9z - y + z = 5 => -10y - 8z = 23 . . (5)
-6 - 3y - 3z + 4y - 2z = 12 => y - 5z = 18 . . . (6)
(6) x 10 => 10y - 50z = 180 . . . (7)
(5) + (7) => -58z = 203
z = 203/-58 = -3.5
From (6), y - 5(-3.5) = 18 => y = 18 - 17.5 = 0.5
From (4), x = -6 - 3(0.5) - 3(-3.5) = -6 - 1.5 + 10.5 = 3
x = 3, y = 0.5, z = -3.5
For the third digit you can use any of the 8<span> digits not already used.
For the next digit, there are </span>7<span> choices.
And for the final digit there are </span>6<span> choices left.
Multiplying the values together gives the stated answer: </span>9<span> x </span>9<span> x </span>8<span> x </span>7<span> x </span>6<span>.</span>
Answer: hey im not sure, but i think your supposed to solve 7x-6 and 9+12x. Add these two together and times it by 55. Im not syre if this is right but u could try it.
No I don't, I never really heard any music from them, but that doesn't mean you can't like that type of music.
Anyway have a nice day! :D
