I believe the answer is 5. I multiplied 5 to -4 and that’s -20 and I’m guessing since slope-intercept form is y=Mx+b I’m thinking b=4 and the slope being 5 matches the output. -16=5(-4)+4
        
             
        
        
        
Answer:
3  19/20
Step-by-step explanation:
So...
The first step is to find a common denominator between the 2. The smallest common denominator is 20. So you would do 3/4 times 5/5 which is 15/20. (2 15/20)
1/5 times 4/4 = 4/20(1 4/20)
So the final step is to add them together
2 15/20 + 1 4/20= 3 19/20. 
This is the most simplified answer you can get.
 
        
             
        
        
        
Answer:
The number is 5
Step-by-step explanation:
If we need to find the hidden number, Which for simplicity's sake we will denote as "n", lets first write out the equation. 
"2 x [n + (-3)] = 4"
We can work through this problem backwards. if we need two times the sum of "n" and (-3) to get to 4, the only number that can be multiplied by 2 to get a product of 4 is 2, so "n" + (-3) must equal 2. so, From here, we can figure out that since 5 + (-3) equals 2, "n" Must equal 5. so, if we plug in 5 for "n" the equation looks like this:
"2 x [5 + (-3)] = 4"
So, since the equation makes sense, the answer is, "n = 5"
 
        
             
        
        
        
Answer:
Y = 27.
Step-by-step explanation:
40 -  13 = 27. If we check our math 13 +27 does equal 40 making the equation correct.
