NAME2DATEPERIODAnticipation GuideStep 1Before you begin Chapter 2 Read each statement. Decide whether you Agree (A) or Disagree (D) with the statement. Write A or D in the first column OR if you are not sure whether you agree ordisagree, write NS (Not Sure).STEP 1A, D, or NSSTEP 2A or DStatement1. When writing equations the phrases as much as, is, and isidentical to, all suggest the equals sign.2. The solving an equation strategy cannot be used if anequation is not given in the problem.3. Given a true equation, any value can be added or subtractedto both sides resulting in a true equation.4. Since the equation t - 23 54 involves subtraction,subtraction would be used to solve for t.15. To solve 21 -7x, you could divide by -7 or multiply by - .7Copyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.6. To solve equations with more than one operation, undooperations in the same order as the Order of Operations.7. Equations with the variable on both sides have no solution.3are all examples of ratios.8. 3 to 5, 3:5, and 51249. Because 5 12 15 4, is in proportion to .15510. A percent of change is found by dividing the amount ofchange by the original amount.11. Equations containing two variables cannot be solved sincevariables cannot be added or subtracted from each side ofthe equation.12. To find a weighted average, extremely high or low valuesare not included.Step 2After you complete Chapter 2 Reread each statement and complete the last column by entering an A or a D. Did any of your opinions about the statements change from the first column? For those statements that you mark with a D, use a piece of paper to write anexample of why you disagree.Chapter 23Glencoe Algebra 1Chapter ResourcesLinear Equations
NOMBRE2FECHAPERÍODOEjercicios preparatoriosEcuaciones linealesPaso 1Antes de comenzar el Capítulo 2 Lee cada enunciado. Decide si estás de acuerdo (A) o en desacuerdo (D) con el enunciado. Escribe A o D en la primera columna O si no estás seguro(a) de la respuesta,escribe NS (No estoy seguro(a)).PASO 1A, D o NSPASO 2AoDEnunciado1. Al escribir ecuaciones, los enunciados: tanto como, es y esidéntico a, sugieren el signo de igualdad.2. Al resolver un problema, no se puede usar una estrategia deecuación si el problema no incluye una ecuación.3. Dada una ecuación verdadera, se puede sumar y restarcualquier valor de ambos lados de la ecuación, lo cual resultaen una ecuación verdadera.4. Puesto que la ecuación t - 23 54 implica sustracción, éstase usaría para despejar t.5. Para resolver 21 -7x, podrías dividir entre -7 o multiplicar1por - .77. Ecuaciones con la variable en ambos lados no tienen solución.38. 3 a 5, 3:5 y son todos ejemplos de razones.51249. Dado que 5 12 15 4, está en proporción a .15510. Un porcentaje de cambio se encuentra dividiendo la cantidad decambio entre la cantidad original.11. Ecuaciones que contienen dos variables no pueden resolverseporque las variables no se pueden sumar o restar de cada ladode la ecuación.12. Para calcular el promedio ponderado, no se incluyen los valoresextremadamente altos o bajos.Paso 2Después de completar el Capítulo 2 Vuelve a leer cada enunciado y completa la última columna con una A o una D. ¿Cambió cualquiera de tus opiniones sobre los enunciados de la primera columna? En una hoja de papel aparte, escribe un ejemplo de por qué estás en desacuerdo con losenunciados que marcaste con una D.Capítulo 24Álgebra 1 de GlencoeCopyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc.6. Para resolver ecuaciones con más de una operación, anula lasoperaciones en el mismo orden en que lo establece el orden delas operaciones.
