The number required is 2/3 because 3*(2/3)+2*(3/2) = 5
A natural number is doubled when added to its reciprocal. Find that number!
the reciprocal is a factor by which you multiply a given number so that their product is 1. ex. 3/5 is the reciprocal of of 5/3.
-10 & 6Let x be the certain number, so the reciprocal is (1/x). You can then set up the following equation to solve for x:x+4 = 60*(1/X)x+4 = 60/xx*(x+4) =x*(60/x)x2+4x = 60x2 + 4x - 60 =0(x+10)(x-6) = 0x+10 = 0 & x-6=0So, x=-10 & x=6
Opposites in math are called inverses. There are two of these inverses: an additive and a multiplicative. The additive inverse of a number is that number multiplied by -1. If this is added to the number, then the result will be 0. The multiplicative inverse of a number is its reciprocal. This is the number converted into a fraction then flipped. If you multiply a number with its multiplicative inverse, the result will be 1.
2 and 4
If: 6x+8 = 32 Then: x = 4
