How can you write the product of a number and a sum as the sum of two products?
x*(y+z) = x*y + x*z This is the distributive property of multiplication over addition.
The sum of two numbers is 10 and their product is 20 find the sum of the reciprocal of the number?
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
Find the positive numbers x and y such that their sum is 35 and product x 2 y 5 is a maximum?
x = 10, y = 25
What shows the product of 6 and x decreased by the sum 6 and y?
6x - (6 + y)
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
The sum of x and y decreased by their product?
The sum of x and y decreased by their product is (x + y)- xy.
What is the product of 3 and x divided by the sum of x and y?
3x over x + y
Find the sum of the reciprocals of two real numbers given that these numbers have a sum of 150 and a product of 40?
1/x + 1/y = (y+x)/xy But y + x = sum = 150, and xy = product = 40 So sum of reciprocals = 150/40 = 3.75
If the sum of two numbers is 7 and there product is 25 what is the sum of there reciprocals?
Suppose the two numbers are x and y. Then, the sum of THEIR reciprocals is 1/x + 1/y = y/xy + x/xy = (y + x)/xy = 7/25
The sum of two number is 10 and their product is 30 the sum of their reciprocals is?
Suppose the numbers are x and y. The sum of their reciprocals = 1/x + 1/y = y/xy + x/xy = (y+x)/xy = (x+y)/xy = 10/30 = 1/3
How can you write the product of a number and a sum as the sum of two products?
x*(y+z) = x*y + x*z This is the distributive property of multiplication over addition.
The sum of two numbers is 10 and their product is 20 find the sum of the reciprocal of the number?
Suppose the numbers are x and y Then the sum of their reciprocals is 1/x + 1/y = y/xy + x/xy = (y+x)/xy = 10/20 = 1/2
Find the positive numbers x and y such that their sum is 35 and product x 2 y 5 is a maximum?
x = 10, y = 25
What shows the product of 6 and x decreased by the sum 6 and y?
6x - (6 + y)
Twice the sum of x and y and The sum of twice x and y?
Twice the sum of 'x' and 'y' . . . 2(x+y) The sum of twice 'x' and 'y' . . . (2x+y)
What is the difference between twice the sum of x and y and the sum of twice x and y?
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
The sum of two numbers is 28 and their product is 7 find the sum of the reciprocals of the numbers?
x + y = 28 x*y = 7 x=7/y replacing X in eq 1 7/y+y=28 y^2 - 28y + 7 = 0 using above solutions find the reciprocal and sum -- Dhruv
