3. Write two numbers, neither of which is 28 , whose LCM is 28 .

(b) The increase in price of a flight to Mumbai was \( £ 48 \) Work out the price of a flight to Mumbai after the increase.

4) \( 10-7 x=80 \)

a) (1) \( \frac{1}{1000} \mathrm{~mm}=\frac{1}{10^{3}} \mathrm{~mm}=10^{-3} \mathrm{~mm} \) (2) \( \frac{1}{100000} \mathrm{~cm}=\frac{1}{10^{3} 1} \mathrm{em}=10^{-5} \mathrm{~cm} \) (3) \( \frac{1000000}{1000} \mathrm{~mm}=\frac{10^{-6} \mathrm{~mm}}{10^{6}} \mathrm{man}=10 \)

Determine whether a regular hexagon will tessellate the plane. Explain. Because Select Choice \( v^{3} \) Select Choice \( \vee \) a factor of \( 360^{\circ} \), a regular hexagon Select Choice \( \checkmark \) tessellate the plane.

Rotating \( M(-5,1) 180^{\circ} \) about the origin and then translating along \( \langle-3,4\rangle \) will give the same result as translating along \( \langle-3,4\rangle \) and then rotating \( 180^{\circ} \). T True Oalse
