A bus driver has a tax credit of \( € 60 \) a week and pays income tax on all his wages standard rate of \( 20 \% \). If he pays \( € 140 \) in income tax for the week, find his gross weekly wage.

5) \( m+p \div 5 ; \) use \( m=1 \), and \( p=5 \)

posible: \( -10+2)=(-6+2) \cdot(-7+3) \)

Determinar si es falso o verdadero: Sean \( H_{1} \) y \( H_{2} \) subespacios de un espacio vectorial \( V \). Entonces \( H_{1} \cap H_{2} \) es un subespacio de \( V \).

2) \( a-5-b ; \) use \( a=10 \), and \( b=4 \)
