Answer:
m<HJK = 40°
Step-by-step explanation:
Given:
m<HJK = 3x - 2
m<KJL = 50°
Required:
m<HJK
Solution:
m<HJK + m<KJL = 90° (complementary angle)
Substitute 
3x - 2 + 50 = 90
Add like terms 
3x + 48 = 90
3x + 48 - 48 = 90 - 48
3x = 42
3x/3 = 42/3
x = 14
✅m<HJK = 3x - 2
Plug in the value of x
m<HJK = 3(14) - 2 = 42 - 2
m<HJK = 40°
 
        
             
        
        
        
14 is your answer
Explanation:
If he has 16 now because he bought 9. You would do 16 - 9 which equals 7. And if he sold half of his coins that means he has 14.
14-7=7

Answer:
30.2 - 13.7=n
Step-by-step explanation:
To get how far he ran you have to subtract 30.2 from 13.7 therefore giving you  16.5 which will be the total distance he ran after lunch.
 
        
             
        
        
        
5/8 divided by 5 is 0.125
        
             
        
        
        
4(8 - x) = 8, 32 - 4x = 8, -4x = -24, So x = 6
