Find the ordered triple of these equations. X + y + z = 12 y = 1 X - Y - Z = 0

patriot [66]

Answer:

the ordered triple of these equations will be:

(x, y, z) = (6, 1, 5)

Step-by-step explanation:

Given the equations

$x + y + z = 12$

$y=1$

$x - y - z = 0$

$y=1$

We can get the value of x by adding the first and third equation

$x + y + z = 12$

$x-y-z=0$

so the equations become

$x+x+y-y+z-z=12+0$

$2x = 12$

$x = 6$

Putting x = 6 and y=1 in the first equation $x+y+z=12$

$6 + 1+ z = 12$

$7 + z = 12\\z = 12 -7$

$z = 5$

Therefore, the ordered triple of these equations will be:

(x, y, z) = (6, 1, 5)

Which equation is not equivalent to the formula d = rt? r equals t over d r equals d over t t equals d over r d = tr

Gennadij [26K]

Question restated.
which is not equivalent to d = rt?
r = t/d
r = d/t
t = d/r
d = tr
If we divide both sides of the original equation by t, we are left with r = d/t, so we know that this is true. if we compare this, however, with the first item on the list, we can see that t/d does not equal d/t, so the first item on the list is the wrong one.
