Answer:
the marked answer is correct
Step-by-step explanation:
The desired end result is an identity matrix in the first three columns. The diagonal values are 1, as needed, so what remains is to eliminate the off-diagonal values. In row 2 that can be done by adding row 3 to it.
The next step should be to add rows 2 and 3 and replace row 2 with that sum.
Answer:
it's 13a+2 pal!
Step-by-step explanation:
A
Because X isn’t repeated in W but there are repeats in the others.
Step-by-step explanation:
5B+4F= $30.76
×3
15B+12F= $92.28
----------------------------
8B+6F= $48.28
×2
16B+12F= $96.56
----------------------------
Cost of one burger:
$97.56-$92.28= $4.28 (final ans)
Cost of one fries:
$30.76-5($4.28)= $9.36 (for 5 fries)
$9.36÷5= $1.87 (final ans)
So the problem ask to find and convert the area into square meters. So to convert is you must do the cross multiplication process that could cancel out unit and made the answer into a square meter, so the answer would be 1. x10^-12m^2.
