Supplementary angles are two angles whose measures sum to a 180 degrees and complementary are the sum have to add up to 90 degrees.So 180÷2=90;90÷2=45;180÷6=30 and 90÷6=15.Altough the answer is A.
        
             
        
        
        
To solve for a number x,
3x+4x-2=15
7x-2=15
7x=17
x=2 3/7 
or x=~2.43
was one of your answer choices either of the first two equations?
        
             
        
        
        
Answer:
The solution to the inequality is:

The solution graph is also attached below. 
Step-by-step explanation:
Given 
We are given the expression

To determine
Solve for x
Given the expression

Subtract 5 from both sides

Simplify

Multiply both sides by 3

Simplify

Thus, we conclude that:
 
Therefore, the solution to the inequality is:
