How do you calculate 2 percent of 25?
You multiply 2/100 x 25, or the equivalent 0.02 x 25.
If The sum of 2 numbers is 25 and sum of their reciprocals is 0.25 then what are the numbers?
x+y=251/x + 1/y=.25 Solve for y in both: y=25-x 1/y=.25-1/x, so y=1/(.25-1/x) Use substitution: 25-x=1/(.25-1/x) (25-x)(.25-1/x)=1 6.25-25/x -.25x+1=1 Combine like terms: -.25x+6.25-25/x=0 Multiply everything by x: -.25x^2 +6.25x-25=0 Multiply everything by negative 1: .25x^2-6.25x+25=0 Multiply everything by 4: x^2 -25x +100=0 Use the quadratic formula: x=[25±√(25^2 -4(1)(100)]/2(1) x=[25±√(625-400)]/2 x=[25±√225]/2 x=(25±15)/2 x=40/2 or x=10/2 x=20 or x=5 Plug these values into the original equation, and you will see that y also = 20 or 5. So, the two pairs of numbers that satisfy the original equation are: x=5, y=20; and x=20, y=5

If The sum of 2 numbers is 25 and sum of their reciprocals is 0.25 then what are the numbers?
x+y=251/x + 1/y=.25 Solve for y in both: y=25-x 1/y=.25-1/x, so y=1/(.25-1/x) Use substitution: 25-x=1/(.25-1/x) (25-x)(.25-1/x)=1 6.25-25/x -.25x+1=1 Combine like terms: -.25x+6.25-25/x=0 Multiply everything by x: -.25x^2 +6.25x-25=0 Multiply everything by negative 1: .25x^2-6.25x+25=0 Multiply everything by 4: x^2 -25x +100=0 Use the quadratic formula: x=[25±√(25^2 -4(1)(100)]/2(1) x=[25±√(625-400)]/2 x=[25±√225]/2 x=(25±15)/2 x=40/2 or x=10/2 x=20 or x=5 Plug these values into the original equation, and you will see that y also = 20 or 5. So, the two pairs of numbers that satisfy the original equation are: x=5, y=20; and x=20, y=5
