10 The temperature in Amsterdam is \( 2^{\circ} \mathrm{C} \). The temperature in Helsinki is \( -7^{\circ} \mathrm{C} \). How many degrees warmer is it in Amsterdam than in Helsinki

Question A retiree decided to pick up gardening and planting trees as a hobby. A new tree was planted, standing at just 30 inches tall. After 8 years, the tree is now 70 inches tall. What is the slope in this situation? Do not include units in your answer.

Factor out the greatest common factor. If the greatest common factor is 1 , just retype the polynomial. \( 15 c^{4}-15 c \)

octerminc \( 5 i \) los coterminales o ne \( 1800^{\circ} \) y \( 280^{\circ} \) \( \frac{2 n}{5} \) rady \( -2 \frac{11}{} \) e \( 30^{\circ} \) y 110

Question 2 What number is a tally of the total frequency for the value and any values listed above it?

9. Evaluate each of the following: \( \begin{array}{llll}\text { (i) } 2 \frac{1}{2}+3 \frac{1}{4} & \text { (ii) } 8 \frac{1}{5}+2 \frac{1}{3} & \text { (iii) } 5 \frac{1}{3}-1 \frac{1}{4} & \text { (iv) } 10 \frac{1}{12}-3 \frac{3}{4}\end{array} \)
