Answer:
5/3
Step-by-step explanation:
The opposite of a number always has to have the same distance from zero, positive or negative. So in this case, since -5/3 is a negative fraction, the answer would be 5/3. This fraction may be positive but they have the same distance from zero. 
 
        
                    
             
        
        
        
Roots of the equation 3x² -3x-6=0 are -1 and 2,
all choices are given wrong
3*2²-3*2-6=0
12-6-6=0
0=0, which is true , so root is 2
3*20²-3*20-6=0
600-60-6=0
534=0  which is wrong, so root is 2, but not 20 
        
             
        
        
        
Hi there!
Let the first number be represented by X. 
The second number (which is 2 more than four times the other), can be represented by 4X + 2.
We can now find the sum of this expression.
X + 4X + 2 
Collect terms
5X + 2
The sum of the numbers is 18. Therefore we can set up the following equation.
5X + 2 = 18
Subtract 2.
5X = 16
Divide both sides by 5.
X = 16/5 = 3 1/5.
Therefore, the first number is 3 1/5. To find the second number we must plug in X = 3 1/5 into the expression 4X + 2
4 * (3 1/5) + 2 = 12 4/5 + 2 = 14 4/5
The two numbers are

~ Hope this helps you!
