A store sells 2.75 liters of juice in one bottle and 1.25 liters in another. How many liters of juice do you have altogether?

34. \( 5-5^{2}+(2-4)= \) 35. \( (8-10) \times(5+3)-10= \) 36. \( \frac{10+5^{2}-3}{2^{2}+2(5-3)}= \)

2. Sea \( a \in Z^{+} \)tal que \( (a, 6)=2 \); si se divide \( a \) por 6 , ¿Cuáles son los posibles valores para el residuo?

What is the value of \( \sqrt{729}-\sqrt{7.29} \) ? \( \begin{array}{llll}\text { A. } 2.7 & \text { B. } 24.7 & \text { C. } 24.3 & \text { D. } 29.7\end{array} \)

20.(1ponit) Add: \( (+1)+(-4)+(-2)+(+2)+(-9) \)

Divide: \( (+120) \div(-6) \)
