Answer:
Step-by-step explanation:
hello :
the system is : x+y+z=-6.....(1)
x-y+3z=-18.....(2)
2x+2y+2z=-8.....(3)
use (3): 2(x+y+z) = - 8 so : x+y+z = -4
use (1) : x+y +z = -6 -6=-4 false
no solutions
Answer:

Step-by-step explanation:
We are actually using Pythagorean theorem here but to be simple
we can use the equation:
D(distance)=
=
(If you meant 16 instead of 6 the answer would be 15)
Hope this helps!

Step-by-step explanation:
<u>Step 1: Define</u>
-2(x - 3) < 4
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide -2 on both sides: x - 3 > -2
- Add 3 to both sides: x > 1
Here we see that any value <em>x</em> greater than 1 would work as a solution to the equation.
I count 5. There could be more. Sorry. Don't have scratch paper at the moment.
An hour has 60 minutes in it, so the simplified form would be
2 14/60 (The 2 should be the whole number in front of the fraction)
In order to change it into a decimal, change it into an improper fraction and divide
134/60
