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 solve the equation (18 − 10)x + 30 = 80, we need to simplify it first.
(18 - 10)x + 30 = 80
(8)x + 30 = 80
8x + 30 = 80
Next, we can isolate the variable x by subtracting 30 from both sides.
8x + 30 - 30 = 80 - 30
8x = 50
Finally, divide both sides of the equation by 8 to solve for x.
8x/8 = 50/8
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 solve the equation (18 - 10)x + 30 = 80 for x.
First, subtract 10 from 18:
18 - 10 = 8
Next, substitute this value into the equation:
8x + 30 = 80
Now, subtract 30 from both sides of the equation:
8x = 80 - 30
8x = 50
Finally, divide both sides by 8 to solve for x:
x = 50 / 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 by subtracting 10 from 18:
8x + 30 = 80.
Then, let's isolate the variable x by subtracting 30 from both sides of the equation:
8x = 80 - 30,
8x = 50.
Finally, to solve for x, we divide both sides of the equation by 8:
x = 50 / 8,
x ≈ 6.25.
Therefore, the pig gained approximately 6.25 kilograms each week.
