Answer:
5.97 ● 10^24 in standard form is: 5.97⋅10^24
Step-by-step explanation:
2 pints. random word, random words, random words, and random words. explained it really well, didn't I?
7.5% of $80 = $6
Here's why:
Using proportions.
⠀
⠀
⠀ x 7.5
⠀ ------- = --------
⠀ 80 100
⠀
7.5 times 80 = 600
100 times x = 100x
600 divided by 100 = 6
x = 6
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
