Two students, raymond and shauna, are trying to get city council members to vote for a new park along the river. 2/6 of the 24 council members say they already support the idea, but that's not enough. at least 13 council members must support the idea before the park is approved. how many more city council members must raymond and shauna convince? 8 7 6 5

They must convince 5 members.

Step-by-step explanation:

Given,

The total number of council members = 24,

Since,  2/6 of the council members say they already support the idea,

So, the number of members who already support the idea =

= 8

Now, the number of members who have to support = 13,

Hence, the remaining members who must support the idea = total members who have to support - members who already support

= 13 - 8

= 5

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
