Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.

How do you write an expression in quadratic form?
Write an expression consisting of up to three terms:One term in which the key variable is squared,one term with a multiple of the variable, anda constant.The first of these MUST be present. The three terms must be added or subtracted.
To evaluate a variable expression you must do what to values for the variable?
You must substitute values for the variable.
How do you simplify this circuit?
To simplify a circuit you must first find a Boolean expression for the circuit and then apply Boolean algebra to take it down to the simplest form, to implement the fewest gates.
How do you simplify expessions?
To simplify an expression you must combine the variables and the constants. Then write the simplified version of the expression so that the expression isn't solved, just simplified. 1a+2(a+5)=2a+7
Can you solve for a variable in an expression?
No, you can only simplify an expression. To solve for a variable, it must be in an equation.
What must you do to evaluate a variable expression?
you have to undo what ever's being done to the variable :p
What must be done to the expression x plus 108 to make it equal x?
Subtract 108.
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.
When you need to satisfy two or more criteria to initiate an event in a program you must make sure that the second decision is made entirely independently of the first decision?
Evaluate the criteria before executing the conditional expression. In pseudocode:result1 = evaluate( criteria1 );result2 = evaluate( criteria2 );if( result1 && result2 ) initiate_event;Note that this is not the same as the following:if( evaluate( criteria1 ) && evaluate( criteria2 )) initiate_event;If the evaluation of criteria1 fails for any reason, then the whole expression fails and criteria2 is never evaluated. so if the evaluations must be done independently of each other, then they must be done prior to the conditional expression, storing the results for use in the conditional expression.
What must be done to the expression x divided by 8.4 to make it equal x?
It is: x/8.4 times 8.4 = x
What is the difference between simplify and solve when talking about an equation or expression?
"Simplify" means to make something simpler. For example, most people would agree that 3x is simpler than x + x + x. "Simplify" is something you do with an expression. However, simplifying things can also help in solving equations.To "solve" means to find the value or values of the variable or variables, that make an equation true. For example, if you have the equation 2x + 1 = 7, solving it means figuring out what value "x" must have, in this case 3, to make the equation true.
What is the value of the expression 19 - 4 times 2 plus 8?
19 - 4 * 2 + 8 = 19 - 8 + 8 = 19 The multiplication must be done first: remember BIDMAS/PIDMAS/BODMAS/PODMAS
P?
P stands for Parenthesis. Which means in a numerical expression you must do the sums that are in parenthesis first.
How do you convert decimals into lowest terms?
first you must turn the decimal into a fraction. then simplify it. Okay so i put 45 over 100
