To find the number of kilograms the pig gained each week, we can solve the equation (18 − 10)x + 30 = 80 for x.
First, simplify the equation: (18 − 10)x + 30 = 80
8x + 30 = 80
Subtract 30 from both sides: 8x = 50
Divide both sides by 8: x = 6.25
Therefore, the pig gained 6.25 kilograms each week.
Case bought a 10-week-old pig that weighed 30 kg. At 18 weeks, the pig weighed 80 kg. The equation (18 − 10)x + 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? Responses
