Answer:
The number is -1/2
Step-by-step explanation:
Let x be the number
2x+8 = 7
Subtract 8 from each side
2x+8-8 = 7-8
2x = -1
Divide each side by 2
2x/2 =-1/2
x = -1/2
The number is -1/2
 
        
                    
             
        
        
        
Answer:
option C is correct answer ..
Step-by-step explanation:
 angle A + angle B + angle C = 180° ( by angle sum property of triangle )
3x + 4x-19+ 3x -1 = 180 
10x + -20 = 180 
10x = 180 +20 = 200 
x = 200/10 = 20 °
angle A = 3× 20 = 60 °
angle B = 4× 20 - 1 9 = 61 °
angle C = 3× 20 -1 = 59 °
angle B is greatest so side opposite to it will be greatest in length ....so length of AC is greatest ....
so option C is the correct answer of this question ...

Answer: 5/6 > 29/36
<u>Find Common Denominator</u>
6: 6,12,18,24,30,36
36: 36,72,106
CD=36
<u>Multiply both sides by 6</u>
5/6×6/6=30/36
<u>Compare</u>
30/36 > 29/36
<u>Therefore</u>
5/6 > 29/36
