Hey there,
Your question states: <span>What is the value of the expression |-7| + |-4|
Sense they both are absolute values, they are pretended to be as normal numbers. By simplifying this, your correct answer would be 11.
Hope this helps.

Answer:
NA
a = 53
Step-by-step explanation:
A bisector creates two equal angles. Set them equal to each other.
5a - 160 = 2a - 1 ( subtract 2a from both sides)
3a = 159 (add 159 to both sides)
a = 53 (divide by 3)
