They want you to associate the number with how many boxes.

9 students watched cartoons and there are 3 boxes
9/3 = 3, this means the key is 3. 1 Box = 3 students

For sports, 6 students watched, 6/3 = 2 Boxes

Movies, 3/3 = 1 Box

Find the line through

Kaylis [27]

Answer:

$(\frac{1}{2},\frac{-1}{2},\frac{1}{2})$

Step-by-step explanation:

We have been given the intersection coordinates:

(7,1,-6) and perpendicular to the line x=-1+t ,y=-2+t and z=-1+t

From the condition of perpendicularity we know:

$(7,1,-6)(x,y,z)$

$\Rightarrow 7x+y-6z=0$

Now, we have given x=-1+t , y=-2+t and z= -1+t

$7(-1+t)+(-2+t)-6(-1+t)=0$

$-7+7t-2+t+6-6t=0$

$\Rightarrow -3+2t=0$

$2t=3$

$t=\frac{3}{2}$

Now, substituting t in the given coordinates x,y and z we get:

$x=-1+\frac{3}{2}=\frac{1}{2}$

$y=-2+\frac{3}{2}=\frac{-1}{2}$

And $z=-1+\frac{3}{2}=\frac{1}{2}$

Aleksandr [31]

Answer:

1. x = 12

2. x = 5

Step-by-step explanation:

1. -222 = -2x - 12x - 54

-222 = -14x - 54

-168 = -14x

x = 12

2. 154 = 2x + 12x + 84

154 = 14x + 84

70 = 14x

x = 5
