x - 13 = -40
x = 13 - 40 = -27
do the other in like wise
Thank you guys and gals for all your help.
x = 13 - 40 = -27
do the other in like wise
N = -40 + 13 = -27.
5 + N = -9.
N = -9 + (-5) =
-27
-14
1. For the number sentence _______ + (-13) = -40:
To find the unknown addend, we can use algebraic reasoning. Since we are adding a negative number (-13), we can subtract 13 from both sides of the equation to isolate the unknown addend:
_______ + (-13) - (-13) = -40 - (-13)
This simplifies to:
_______ = -40 + 13
_______ = -27
Therefore, the unknown addend in the first number sentence is -27.
2. For the number sentence 5 + _______ = -9:
To find the unknown addend, we can once again use algebraic reasoning. Since we are adding a positive number (5), we can subtract 5 from both sides of the equation to isolate the unknown addend:
5 + _______ - 5 = -9 - 5
This simplifies to:
_______ = -14
Therefore, the unknown addend in the second number sentence is -14.
To summarize:
The unknown addend in the first number sentence is -27, and the unknown addend in the second number sentence is -14.
