PLEASE HELP ASAP!! Calculate the amount of tar absorbed by a smoker in one week. The following information will help you with your calculations:
- Assume that a smoker smokes 10 cigarettes a day
- There are 20 mg of tar in most cigarettes (1000 mg = 1 g)
- Approximately 25% of the tar is released in the form of smoke or is exhaled. The remaining 75% is absorbed through the smoker’s lungs.

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 -
