Explanation:

5.

Step1: Escribir la ecuación

Sea \(x\) el número de bloques de Clare. La ecuación es \(x + 6=14\).

Step2: Resolver la ecuación

Restar 6 de ambos lados: \(x=14 - 6\).
\(x = 8\).

6.

Step1: Escribir la ecuación

La ecuación es \(16+18=n\).

Step2: Calcular la suma

\(16 + 18=34\).

7.

Step1: Escribir la ecuación

La ecuación es \(19-6 = m\).

Step2: Calcular la diferencia

\(19-6=13\).

8.

Step1: Calcular la suma

\(4+3+6=(4 + 3)+6=7+6=13\).

9.

Step1: Escribir la ecuación

Si hay 4 filas y 6 conchas en cada fila, la ecuación es \(4\times6=s\).

Step2: Calcular el producto

\(4\times6 = 24\).

Explicación

Un número par es divisible por 2. \(9\div2 = 4.5\), \(14\div2=7\), \(17\div2 = 8.5\), \(21\div2=10.5\). El número par es 14.

Answer:

1. \(8\) blocks.
2. \(34\) acorns.
3. \(13\) ants.
4. \(13\).
5. \(24\) seashells.
6. \(14\).
