Product Information

Our procedure for solving a first-degree equation can be rewritten to give us a procedure for solving a formula for a specified variable. Many of the exercises in previous sections have required the use of more than one rule in the solution process.

If each term of an equation is multiplied by the same nonzero number, the resulting equation is equivalent to the original equation. Example 6 The formula for finding the circumference (C) of a circle is C = 2πr, where π represents the radius of the circle and it is approximately 3. We do not reverse the direction of the inequality symbol since we are multiplying by a positive number, 8. b) The owner of the trucking company said that the payload of a truck must never exceed 4500 pounds (use the variable p for payload).If you leave the solution as a fraction, it will be easier to check that solution in the original equation.

Letter size is shown on our diagram for reference - it is slightly wider than A4 and not quite as tall.Therefore we could divide each side of the equation by 5 and obtain , which is equivalent to the original equation. Ability to solve an equation mentally will depend on the ability to manipulate the numbers of arithmetic. If the item comes direct from a manufacturer, it may be delivered in non-retail packaging, such as a plain or unprinted box or plastic bag. i) (x + 3)(x + 3) (ii) (2y + 5)(2y + 5) (iii) (2a - 7)(2a - 7) (iv) (3a - (1/2))(3a - (1/2)) (v) (1.

To complete an addition (or subtraction) problem, multiply the numerators and denominators of each fraction in the problem by whatever value will make the denominators 12, then add the numerators.You will want to get all the variable terms on one side and all the constant terms on the other side. The answer to the second question involves the techniques for solving equations that will be discussed in the next few sections. We multiply each side of the equation by the lowest common denominator of all the fractions contained in the equation. If the parentheses are first removed, the problems then become just like those encountered previously.

To accomplish this we will use the skills learned while manipulating the numbers and symbols of algebra as well as the operations on whole numbers, decimals, and fractions that you learned in arithmetics. If each term of an equation is divided by the same nonzero number, the resulting equation is equivalent to the original equation. Example 6 The perimeter (P) of a rectangle is found by using the formula P = 2l+ 2w, where l stands for the length and w stands for the width. The O-Ring Seal with the reference OR-52X3-AU90 has an inner diameter of 52 mm and a thickness of 3 mm.We can determine if a value is the solution to an equation by following the same steps used to check an answer.
