A) 3/56 + 27/56 = 30/56 ÷ 2/2 = 15/28

Step-by-step explanation:

So, there's 3/56 cities that have a lake and 27/56 cities that have a river.

Since the question is asking how much have a lake or river, we add them up.

3/56 + 27/56 = 30/56

(Divide by 2 since that's the common factor)

30/56 ÷ 2/2 = 15/28

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
