One of the common difficulties with studying the material in this chapter is being sure about the task at hand. Are you combining expressions using operations to get another rational expression, or are you solving equations for which the results are numbers that are solutions of an equation? To practice making these decisions, determine for each of the following exercises the type of answer you should get: “Rational expression” or “Solutions.” You need not complete the mathematical operations.

- What is the first step in your solution to the equation 10x+2=4x+26 ?arrow_forwardA city planner wants to build a bridge across a lake in a park. To find the length of the bridge, he makes a right triangle with one leg and the hypotenuse on land and the bridge as the other leg. The length of the hypotenuse is 340 feet and the leg is 160 feet. Find the length of the bridge.arrow_forwardSolve the equation 2x + 3y = 6 for y : (a) when x=- 3 (b) in general (c) Which solution is easier for you? Explain why.arrow_forward
- The product of two consecutive integers is 420. Find the integers.arrow_forwardThe product of two consecutive odd integers is 255. Find the integers.arrow_forwardWhen solving an equation with variables on both sides, why is it usually better to choose the side with the larger coefficient of x to be the “variable” side?arrow_forward
- If an equation has fractions only on one side, why do you have to multiply both sides of the equation by the LCD?arrow_forwardExplain why the equation y2+8=12 has two solutions.arrow_forwardA meditation garden is in the shape of a right triangle, with one leg 7 feet. The length of the hypotenuse is one more than the length of one of the other legs. Find the lengths of the hypotenuse and the other leg.arrow_forward
