How do you solve this equation B-3(B-4(1-B)) equals 54?

By following BODMAS, evaluate the inner brackets first, collecting terms together as you go: B - 3(B - 4(1 - B)) = 54 → B - 3(B - 4 + 4B) = 54 → B -3(5B - 4) = 54 → B - 15B + 12 = 54 → -14B = 42 → 14B = -42 → B = -3 Check by substituting back into the original equation: B - 3(B - 4(1 - B)) → -3 - 3(-3 - 4(1 - -3)) → -3 - 3(-3 - 4(4)) → -3 - 3(-3 - 16) → -3 - 3(-19) → -3 + 57 → 54 as required.


How do you solve a AND b OR c in logical operators?

There is nothing to "solve". You can evaluate the expression when each of a, b and c are TRUE or FALSE. But that is not solving.

What does it you to evaluate an algebraic expression?

To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]

What do you call replacing a variable in an expression by a number?

A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46

What is associativity of operators?

In simple, For operators, associativity means that when the same operator appears in a row, then to which direction the evaluation binds to. In the following, let Q be the operator a Q b Q c If Q is left associative, then it evaluates as (a Q b) Q c And if it is right associative, then it evaluates as a Q (b Q c) It's important, since it changes the meaning of an expression. Consider the division operator with integer arithmetic, which is left associative 4 / 2 / 3 <=> (4 / 2) / 3 <=> 2 / 3 = 0 If it were right associative, it would evaluate to an undefined expression, since you would divide by zero 4 / 2 / 3 <=> 4 / (2 / 3) <=> 4 / 0 = undefined
