Answer:
x + y + z = - 22
Step-by-step explanation:
Reciprocal of a : - 6,
Reciprocal of b : 2
Therefore if x is the sum of the reciprocals of a and b, it will be - 6 + 2 = - 4. x will be - 4.
Respectively if y is the product of the reciprocals of a and b, it will be - 6 
2 = - 12. y is - 12. And if z is twice the reciprocal of a / the reciprocal of b, it will be the following,
z = 2(- 6) / 2
= - 12 / 2 = - 6
And x + y + z = - 4 - 12 - 6 = - 22. That is your solution.
AC = 2 (MN)
AC = 2 (9)
AC = 18
answer is <span>18 ft</span>
Is this from k12? i am a k12 student, and the answer should be 2.2 units but I could be wrong.
Do cross multiplication
<u>6</u> = <u>x</u>
18 12
Now cross multiply
(6)(12) = (18)(x)
72 = 18x
Divide both sides by 18
<u>72</u> = <u>18x</u>
18 18
4 = x
