Question

1. assessment there are 44 marbles in a jar. some are red and 23 are blue. julie adds 13 red marbles to the jar. now how many red marbles are in the jar? which equations show a way to solve the problem? a ( 44 - 23 = 21 ) ( 21 + 13 = 34 ) b ( 44 - 23 = 21 ) ( 21 - 13 = 8 ) c ( 23 + 21 = 44 ) ( 44 - 13 = 31 ) d ( 23 + 44 = 67 ) ( 67 + 13 = 80 )

Explanation:

Step1: Encontrar canicas rojas iniciales

Restar las azules del total:
$44 - 23 = 21$

Step2: Agregar las canicas rojas nuevas

Sumar las nuevas rojas al valor anterior:
$21 + 13 = 34$

Step3: Identificar la opción correcta

Verificar que la secuencia de ecuaciones coincida con los pasos.

Answer:

A. $44 - 23 = 21$
$21 + 13 = 34$
El número final de canicas rojas es 34.
