3s+28=85, take away 28 from both sides of the equals to give you 3s=57, divide by 3 on both side to give you s=19.
The answer would be 6 weeks.
First, you do 44 divided by 4 to get 11 kg per week. Now you divide 66 by 11 to get 6 weeks.
Answer:
336x + 624
Step-by-step explanation:
(x - 3) + (x - 6) + x = 63
x - 3 + x - 6 + x = 63
Combine like terms
3x - 9 = 63
Isolate the constant
3x - 9 + 9 = 63 + 9
3x = 72
Isolate the viable
3x / 3 = 72 / 3
x = 24
