Answer:
1. Associative Property of Multiplication
2. Multiplicative Identity Property
3. Multiplicative Inverse Property
4.Additive Identity Property
5. Associative Property of Addition
6. Additive Inverse Property
-25.65 - 16.5 + 12.45 = -29.7......he is now at 29.7 ft below the surface
3x + 2y = 10 .....multiply by -2
2x + 3y = 15/2...multiply by 3
------------------
-6x - 4y = -20 (result of multiplying by -2)
6x + 9y = 22.5 (result of multiplying by 3)
-----------------add
5y = 2.5
y = 2.5/5
y = 1/2
3x + 2y = 10
3x + 2(1/2) = 10
3x + 1 = 10
3x = 10 - 1
3x = 9
x = 9/3
x = 3
solution is (3,-1/2)
We'll it keeps on subtracting by 4 to get each number.
-2,-6,-10,-14,-18,-22,-26.
Negative 26 is your answer. Hope this helped!
