x = 22
An expression that represents the sum of a number and 12 is ( x + 12 ), where ( x ) stands for the unknown number. This expression indicates that you take the value of ( x ) and add 12 to it.
In a mathematical expression, a sum is typically represented by the addition operator, which is the plus sign (+). For instance, in the expression (a + b), the terms (a) and (b) are being added together, indicating that this part of the expression represents a sum. Any grouping of terms connected by the plus sign constitutes a sum.

The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
The variable expression that represents the phrase "the sum of the number of dogs and the 6 cats" is ( d + 6 ). In this expression, ( d ) stands for the number of dogs, and the ( 6 ) represents the number of cats. Thus, the expression calculates the total number of pets by adding the dogs and cats together.
An expression that represents the sum of a number and 12 is ( x + 12 ), where ( x ) stands for the unknown number. This expression indicates that you take the value of ( x ) and add 12 to it.
The algebraic expression that represents the sum of 10 and 3 times a number x is 10 + 3x. This expression can be simplified by multiplying 3 with x to get 3x, and then adding 10 to it. In this expression, 3x represents three times the value of x, and 10 represents a constant value added to the product of 3 and x.

3(y+7)
The verbal phrase "the sum of x and y" can be translated into the algebraic expression ( x + y ). This expression represents the addition of the variables ( x ) and ( y ).
The variable expression that represents the phrase "the sum of the number of dogs and the 6 cats" is ( d + 6 ). In this expression, ( d ) stands for the number of dogs, and the ( 6 ) represents the number of cats. Thus, the expression calculates the total number of pets by adding the dogs and cats together.
The algebraic expression that represents fifteen less than the sum of ( y^3 ) and seven is ( (y^3 + 7) - 15 ). This simplifies to ( y^3 - 8 ).
The sum of ( a ) and ( c ) can be expressed simply as ( a + c ). This notation represents the addition of the two variables ( a ) and ( c ) together.
To write an expression that represents the sum of a number and 12, you can use a variable to represent the unknown number. For example, if you let the variable ( x ) represent the number, the expression would be ( x + 12 ). This indicates that you are adding 12 to whatever value ( x ) holds.
