How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
What is an algebra expression you replace each variable with a number?
evaluation, evaluate.
What size is 2x?
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
What is the evaluate your expression for nine minus times negative one?
It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".
What number is the coefficient number?
the number next to a variable that multiplies the variable
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
How do you determine whether a number is a solution of an equation?
Substitute the value found back into the equation, evaluate the expressions and see if the resulting equation is true.
A number that you can substitute for the variable to make the equation true?
A solution!
When you replace the variable with a number and perform the operations you blank an expression?
evaluate.
What is an algebra expression you replace each variable with a number?
evaluation, evaluate.
When you replace each variable with a number and then follow order of operations is called what?
Evaluate
How do you decide if a number is a solution to the inequality?
Substitute the number in place of the variable, and see whether the inequality is then a true statement.
Explain how to find restrictions on the variable in a rational equation?
Substitute the variable in the denominator for a value that will make the denominator have a value of 0 or an imaginary number
Explain how to write and evaluate an algebraic expression.thirteen less than the quotient of forty and a number; evaluate when n = 2?
Sample Response: Replace keywords with variables, numbers, and operations. Less than is subtraction, and the quotient is division. Order matters with subtraction and division. The expression is 40 n -13. To evaluate is the expression, substitute 2 in for the variable, and then use order of operations to simplify. The value when n = 2 is 7.
What does it mean to evaluate an expression?
To evaluate an expression is nothing but to operate the given expression according to the operators given in the expression if it is evaluable i.e, it could be convertable.
What size is 2x?
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
Explain how to write and evaluate an algebraic expression.one more than the product of a number and seven, decreased by five; evaluate when n = 6?
Sample Response: Replace key words with variables, numbers, and operations. More than is addition, product is multiplication, and decreased by is subtraction. The constants are 1, 7, and 5. The expression is 1 + 7n – 5. To evaluate the expression, substitute 6 in for the variable, and then use order of operations to simplify. The value when n = 6 is 38.
