How do you write 3 more than the sum of x and y?
(x+y)+3
The sum of x and y decreased by their product?
The sum of x and y decreased by their product is (x + y)- xy.
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
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 numbers is 36 There difference is 24 Find the numbers?
This is a good exercise in building and solving a set of equations. Let X and Y be the two numbers. Then you are told their sum is 36, so write; X + Y = 36 Then you are told their difference is 24, so write; X - Y = 24 Now elliminate Y by adding the two equations; 2X = 60 and X = 30 . Now you can find Y by substituting this answer into either of the two original equations to get Y = 6.
How do you write 3 more than the sum of x and y?
(x+y)+3
How would you write subtract the sum of 2 and y from x?
x - (y + 2)
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.
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
How do you write an equation showing the sum of the two unknown integers is 41?
x + y = 41, where x and y are unknown integers.
Write an algebric expression for the sum of a number and 8?
y = x +8 where x is the number
How would you write an algebraic expression for the sum of a number and 7?
x+7=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.
The sum of x and y?
x+y
How do you write The quotient of the sum of two numbers and twenty into an algebraic expression?
(x + y)/20
What is 2 times the sum of x and y?
To find 2 times the sum of x and y, you first need to calculate the sum of x and y by adding the two variables together. Once you have the sum, you multiply it by 2 to get the final result. In mathematical terms, the expression for 2 times the sum of x and y can be written as 2(x + y).
