Answer:
The answer is 173,595
Step-by-step explanation:
Firstly, you multiply 815 by the first number of 213 which is 3
So:

Then 815 by the second number:

Then 815 by the third number:

Then you add all the numbers, but you have to put a zero to the right of the second product and two zeroes to the third product and so on..
In this case the addition is :
2445+8150+163000 = 173595
If my calculations are correct the answer is 21 ft
Answer:
(x, y) = (2, 1)
Step-by-step explanation:
Adding the two equations gives ...
2y = 2
y = 1 . . . . . divide by 2
Subtracting the second equation from the first gives ...
0 = 6x -12
0 = x -2 . . . . divide by 6
2 = x
The solution is (x, y) = (2, 1).
