In matrix form, the system is given by
I'll use G-J elimination. Consider the augmented matrix
• Multiply through row 1 by -1.
• Eliminate the entries in the first column of the second and third rows. Combine -2 (row 1) with row 2, and -3 (row 1) with row 3.
• Eliminate the entry in the second column of the third row. Combine -5 (row 2) with row 3.
• Multiply row 3 by 1/3.
• Eliminate the entry in the third column of the second row. Combine row 2 with row 3.
• Eliminate the entries in the second and third columns of the first row. Combine row 1 with row 2 and -1 (row 3).
Then the solution to the system is
If you want to use G elimination and substitution, you'd stop at the step with the augmented matrix
The third row tells us that . Then in the second row,
and in the first row,
1.you Divide 10 and 8 to see how much each can cost
2.The cost for one can of soup is 1.25
3.Then you multiply 1.25 and 5 because you are looking for the cost for 5 cans of soup
4.the answer is 6.25
I'm pretty sure it could be 6,986.5002 dollars. & if you round its 6,986. you multiply 228,317 by 0.06 and then multiply that answer by 0.51. it gives you the 6,986.5002.
45 45 90 right triangle BCA
ratio of leg : leg : hypo = y : y: y√2
in this case hypo = 3√2 so leg = y = 3
answer
y = 3
Answer: subtract
Step-by-step explanation: 0 + (-12) = 0-12.
