Q2
Bronze to aluminum is 25:2
The alloy is bronze plus aluminum, so by adding 25 + 2 you get 27.
Bronze to total is 25:27

25 is 27 as x is to 55

25/27 = x/55

27x = 25 * 55

x = 50.926

Answer: 50.926 kg of bronze

Q3

manipulative toys are 30 out of 70

30/70 * 100 = 42.9%

Answer and Explanation:

The line seems to pass trough the points (0,6) and (-3,4).

Slope is: $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{4-6}{-3-0} =\frac{-2}{-3} =\boxed{\frac{2}{3}}$

The slope of the line should be $\frac{2}{3}$ .
