Answer:
Option c is the correct answer.
Step-by-step explanation:
1 -2 3 -2
6 2 2 -48
1 4 3 -38
R2-6R!=R2
R3-R1=R3
1 -2 3 -2
0 14 -16 -36
0 6 0 -36
R3/6=R3
1 -2 3 -2
0 14 -16 -36
0 1 0 -6
The last row gives y =-6
II row gives 14y-16z=-36 : Substitute for y to get z=-3
From I row x-2y+3z=-2
Substitute for y and z
x=-2+2y-3z = -5
Hence correct solution is
(-5,-6,-3)
Answer:
if im not wrong i think it 81 and 9 cause complementary is 2 angles that add up to 90
Step-by-step explanation:
Hey there! :) How are you? Basically what you said is right.
Question 1: There are 16 oz (ounces) in a pound, so we do 64/16= 4 lbs (pounds).
Question 2: If Jack has 3 pounds of pasta, that would mean he has 48 ounces, since 1 pound is 16 oz, so 16*3= 48 ounces.
Hoped I helped! Have a nice day, and keep smiling! :)
