Question: Help with these math problems? 1. Find three consecutive numbers whose sum is 60?\n\n2.The perimeter of a rectangle is 420 in. The width is 4 in. less than the legnth. What is the legnth of the rectangle.\n\n\n3. Find a number which is 150 greater than its opposite.\n\n\n\n I would also like to see how you got these answers. thanks in advance.

Answer: Let the numbers be x-1,x and x+1.\nTherefore by the problem x-1+x+x+1=60\n=>3x=60\n=>x=60/3=20\nTherefore,the numbers are 19,20 and 21.\n2) Let the width be x.kThen the length is x+4\nThe perimetr is 2(x+x+4)=4x+8 \n=>4x+8=420\n4x=412\n=>x=412/4=103\nTherefore width =103 and the length=103+4=107 m\n(3) Let the number be x\nTherefore x=-x+150\n=>2x=150\n=>x=150/2=75\nTherefore the number is 75\n\n=>
