X - y + z = -7
x + y + z = 1
-------------------add
2x + 2z = -6
x + y + z = 1
x + y - z = 9....multiply by -1
-------------------
x + y + z = 1
-x - y + z = -9 (result of multiplying by -1)
------------------add
2z = -8
z = -8/2
z = -4
2x + 2z = -6
2x + 2(-4) = -6
2x - 8 = -6
2x = -6 + 8
2x = 2
x = 1
x - y + z = -7
1 - y - 4 = -7
-y -3 = -7
-y = -7 + 3
-y = -4
y = 4
so x = 1, y = 4, and z = -4
I think it’s 46.3 units squared that is the answer.
Answer:
The answer is 3.
Step-by-step explanation:
C=dxpi
18x3.14=56.52
6x3.14=18.84
56.52/18.84=3
Answer:
6
Step-by-step explanation:
3n=3(n)
ur replcing n with 2
3(2)=3x2
3x2=6
First you have to find out how much one cost.
In order to do that you have to divide 3.60/6. You would get 6. That is how much one cost. Then you have to multiply 6*2 and you would 12. So the answer is $12. I hope this helps
