Determine the unknown addend in each number sentence._______ + ( − 13 ) = − 40 and 5 + _______ = − 9
Thank you guys and gals for all your help.
x - 13 = -40
x = 13 - 40 = -27
do the other in like wise
N + (-13) = -40.
N = -40 + 13 = -27.
5 + N = -9.
N = -9 + (-5) =
the answer is
-27
-14
To determine the unknown addend in each number sentence, we need to find the number that, when added to the given number, will result in the specified sum.
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.
