5. Write the recursive formula for the following arithmetic sequence 1.5, 4, 6.5, 9.. A.
a = a + 2.5
n n-1
a
C. a, = 1.533 + 2.5(n-1)
D. a, = a. + 1.5
B.
a = 1.5(2.5)*
n-1

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

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:

it is true
