in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in terms of the other. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant speed, list and graph ordered pairs of distances and times, and write the equation d 65t to represent the relationship between distance and time.

Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). For example, use the formulas v s3 and a 6 s2 to find the volume and surface area of a cube with sides of length s 1/2.A.3, apply the properties of operations to generate equivalent expressions. For example, apply the distributive property to the expression 3 (2 x) to produce the equivalent expression 6 3x; apply the distributive property to the expression 24x 18y to produce the equivalent expression 6 (4x 3y apply properties of operations to y integration y. Identify when two expressions are equivalent (i.e., when the two expressions name the same number regardless of which value is substituted into them). For example, the expressions y y y and 3y are equivalent because they name the same number regardless of which number y stands for. Reason about and solve one-variable equations and inequalities.B.5, understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine whether a given number in a specified set makes an equation or inequality true.B.6, use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending.
