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
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.
To find the number of kilograms the pig gained each week, we can use the given equation:
(18 - 10)x + 30 = 80
First, let's simplify the equation:
8x + 30 = 80
Next, let's isolate the variable x by subtracting 30 from both sides:
8x = 50
To solve for x, we divide both sides by 8:
x = 50 / 8
Simplifying the right side, we have:
x = 6.25
Therefore, the pig gained approximately 6.25 kilograms per week.
To find the number of kilograms the pig gained each week, we need to solve the equation (18 − 10)x + 30 = 80 for x.
Let's break down the equation step by step:
1. Start with the number of weeks the pig grew: 18 − 10 = 8.
2. Multiply the number of weeks by the amount of weight gained per week: 8x.
3. Add the initial weight of the pig: (8x) + 30.
4. Set it equal to the final weight of the pig: (8x) + 30 = 80.
Now let's solve the equation to find x:
1. Subtract 30 from both sides: (8x) = 80 - 30 = 50.
2. Divide both sides by 8: x = 50 / 8 = 6.25.
Therefore, the pig gained approximately 6.25 kilograms each week.
