Question

which is not true
A. 5 + 14 = 20 - 1
B. 9 + 5 = 7 + 7
C. 15 = 4 + 11
D. 15 - 9 = 9 -4

Answer 1

Let's evaluate each statement:

A. \( 5 + 14 = 20 - 1 \)
\( 5 + 14 = 19 \) and \( 20 - 1 = 19 \)
True.

B. \( 9 + 5 = 7 + 7 \)
\( 9 + 5 = 14 \) and \( 7 + 7 = 14 \)
True.

C. \( 15 = 4 + 11 \)
\( 4 + 11 = 15 \)
True.

D. \( 15 - 9 = 9 - 4 \)
\( 15 - 9 = 6 \) and \( 9 - 4 = 5 \)
False.

The statement that is not true is **D**.
