Answer:
The answer to your question is:
x = 4
y = -1
z = -3
Step-by-step explanation:
3 x + 2 y + z = 7
5 x + 5 y + 4 z = 3
3 x + 2 y + 3 z = 1
= 45 + 10 + 24 - (30 + 24 + 15)
= 79 - 69
Δ = 10
= 105 + 6 + 8 - (18 + 56 + 5)
= 119 - 79
Δx = 40
= 27 + 5 + 84 - ( 105 + 12 + 9)
= 116 - 126
Δy = -10
= 15 + 70 + 18 - (10 + 18 + 105)
= 103 - 133
= -30
Δz = -30
x = Δx /Δ = 40/10 = 4
y = Δy/Δ = -10/10 = -1
z = Δz/Δ = -30/10 = -3
Answer: a
Step-by-step explanation:
(6.0 x 10^5) x (3.0 x 10^4) = (6 x 3) x 10^(5 + 4) = 18 x 10^9 = 1.8 x 10^10
