Answer:
Step-by-step explanation:
Given :
...................... equation 1
........................ equation 2
solving the system of linear equation by substitution method , substitute equation 1 into equation 2 , that is
collect the like terms
therefore :
substitute into equation 1 to find the value of y , that is
Therefore :
Answer: 130 kg 920 g
Step-by-step explanation:
Given
The weight of the goat is 59 kg 720 g
The combined weight of goat and cow is 190 kg 640 g
Suppose, the weight of the cow is x kg
We know, 1 kg=1000 g
Converting weight into kg
Goat weight
Total weight
Then, the cow weight is given by
First, we would need to divide the number of portraits he can paint (919,191) by the amount of weeks it takes (777), which gives us 1,183 portraits per week. Then, we have to multiply that number by 444, which gives us 525,252, which is our answer to this problem. So Luke can paint 525,252 portraits in 444 weeks.

Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = ← k is the constant of variation
(A)
To find k use the given condition y = 2 when x = 10
k = yx = 2 × 10 = 20, thus
y = ← equation of variation
(B)
When x = 4, then
y = = 5
