Algebra 1 Common Core Student Edition, Grade 8-9

English Spanish

Equation (p. 53) A mathematical sentence that uses an Ecuacion (p. 53) Enunciado matematico que tiene el signo
equal sign. de igual.

Example x + 5 = 3x - 7

Equivalent equations (p. 81) Equations that have the
same solution.

Ecuaciones equivalentes (p. 81) Ecuaciones que tienen la

misma solucion.

Example | = 3 and | + a = 3 + a are

equivalent equations.

Equivalent expressions (p. 23) Algebraic expressions that
have the same value for all values of the variable(s).

Expresiones equivalentes (p. 23) Expresiones algebraicas

que tienen el mismo valor para todos los valores de la(s)

variable(s).

Example 3a + 2a and 5a are equivalent

expressions.

Equivalent inequalities (p. 171) Inequalities that have the
same set of solutions.

Desigualdades equivalentes (p. 171) Las desigualdades

equivalentes tienen el mismo conjunto de soluciones.

Example x + 4 < 7 and x < 3 are

equivalent inequalities.

Evaluate (p. 12) To substitute a given number for each
variable, and then simplify.

Evaluar (p. 12) Metodo de sustituir cada variable por un

numero dado para luego simplificar la expresion.

Example To evaluate 3x + 4 for x = 2,

substitute 2 for x and simplify.

3(2) + 4 =^6 + 4= 10

Event (p. 769) Any group of outcomes in a situation
involving probability.

Example When rolling a number cube, there

are six possible outcomes. Rolling an

even number is an event with three

possible outcomes, 2, 4, and 6.

Suceso (p. 769) En la probabilidad, cualquier grupo de

resultados.

Excluded value (p. 664) A value of x for which a rational
expression f(x) is undefined.

Valor exduido (p. 664) Valor de x para el cual una

expresion racional es indefinida.

Experimental probability (p. 771) The ratio of the
number of times an event actually happens to the number
of times the experiment is done.

P(event) = number of times an event happens

Probabilidad experim ental (p. 771) La razon entre el

numero de veces que un suceso sucede en la realidad y el

numero de veces que se hace el experimento.

n u m er o d e v eces q u e su ced e un su ceso

number of times the experiment is done P{ s uc e s o) = numero de veces que se hace el experimento

Example A baseball player's batting average

shows how likely it is that a player

will get a hit, based on previous

times at bat.
