Answer:
-37
Step-by-step explanation:
for the first equation to equal 4 the x must equal -6. 
because something plus 7 had to equal 4. and we know that -3 + 7 equals 4. Now, -6 ÷ 2 equals -3 and that gives us the right answer.
So now plug -6 into the new problem so now it is 
5 × (-6) - 7 so according the PEMDAS, we do 5 × -6 first which is -30. and -30 - 7 equals -37!!
hope this helps :)
 
        
             
        
        
        
Answer:

= Here, 
 Narasimha invest = 120,000 
 Madhu 135,000
 pavan = 
 
        
             
        
        
        
72/3=24
24/12=2(2 meters a person a day)
2*15=30
15 people can build about 30 meters of fence a day.
 
        
             
        
        
        
For this, no math is even needed! The question says 1,000 people were interviewed. 42% percent of that 1,000 owns an SUV. If it's a percent, it is 42/100, right? Now we have to make that 42/100 out of 1000. We add a zero to the 100 on the bottom (42/1000). We do the same thing on the top. Add a zero! 420. 
SECOND POSSIBLE SOLUTION
Solve this with logic! 42% is nearly 50%. Half of 1,000 is 500. What is closest to 500? 420! This solution is even easier.
Hope this helps you!
