Question

Identify the expression that is not equal to the other three. Explain your reasoning

Answer 1

Answer:

$-\left|7+3\right|$

Step-by-step explanation:

Solve each expression and then compare the results

case 1) we have

$15-\left|-5\right|\\ \\=15-(5)\\ \\=10$

case 2) we have

$\left|-4\right|+6\\ \\=(4)+6\\ \\=10$

case 3) we have

$-\left|7+3\right|\\ \\ =-(7+3)\\ \\=-10$

case 4) we have

$\left|-10\right|\\ \\ =-(10)\\ \\=10$
