Question might not be complete
Answer and explanation:
The signs -1 and -4 lie on the negative side of the number line, left of zero(positive right of zero).
The opposites for each number would be +1 and +4 which would all be on the right side of zero on the number line
Inequality signs or statements to represent greater and lesser number on the number line using the numbers above as examples would be:
-1<+1
-4<-1
+1>-1
+1<4
-1-4<1+4
Numbers that don't have signs attached to them are automatically positive numbers
the m angle ABC is 19x+12
90
Step-by-step explanation:
9 x (3)2 + 9 first do the parenthesis
9 x 9 + 9 I am assuming the 2 was an exponent
81+9
1 1/3
2/3 x 2/1 = 4/3 = 1 1/3
23,4
