Answer
Case bought a 10 week old pig that weighed 30 kg. At 18 weeks the pig weighed 80 kg. The equation (18 − 10)w + 30 = 80 can be used to find the number of kg (x) the pig gained each week.
How many kilograms did the pig gain each week?

To find the number of kilograms the pig gained each week, we can rearrange the equation (18 - 10)w + 30 = 80 to solve for w, which represents the number of weeks.
(18 - 10)w + 30 = 80
8w + 30 = 80
Subtract 30 from both sides:
8w = 50
Divide both sides by 8:
w = 6.25
Therefore, the pig gained 6.25 kilograms each week.
(18 - 10)w + 30 = 80
8w + 30 = 80
Subtract 30 from both sides:
8w = 50
Divide both sides by 8:
w = 6.25
Therefore, the pig gained 6.25 kilograms each week.
