2. There are between 50 and 60 eggs in a basket. When Loza counts by 3's, there are 2 eggs left over. When she counts by 5 's, there are 4 left over. How many eggs are there?

b) \( \frac{1}{2}+\frac{3}{4} \)

c) \( \frac{2}{5}+\frac{2}{3} \)

a) \( \frac{1}{12}+\frac{7}{12} \)

1 The speed of a car is given as \( 45 \mathrm{~m} / \mathrm{s} \) to the a Find the lower and upper bounds within which the car speed can lie b If the car's speed is \( v \mathrm{~m} / \mathrm{s} \), express this range as inequality 2 Find the lower and upper bounds of \( \begin{array}{ll}\text { a } 45 \text { rounded to the nearest integer } \\ \text { b } 126 \text { rounded to } 1 \mathrm{~d} p \\ \text { c } 423 \text { rounded to } 2 \mathrm{~d} p \\ 3 \text { Express each of the following in between the upper and lower bounds } \\ x=347 & \text { b } y=21.36\end{array} \) c \( z=154134 \)

R) \( 4^{2}+2^{2}+1^{2}= \) 8) \( \sqrt{8}+\sqrt{4}+\sqrt{36}= \)
