The sports boosters club is having a bake sale to buy uniforms. they want to raise $250. they need to rent a booth for $20. how many dozen cookies will they need to sell if they charge $3 per dozen?

which equation could be used to solve this problem?

1. 250 = 3c - 20

2. 250 = 3 - 20c

3. 250 = 20 - 3c

4. 250 = 20c - 3

the answer

b. they are parallel and will never intersect.

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
