Answer
Find out the what is the new ratio of the number of geese to the number of hens .
To prove
As given
There are 6 geese and 9 hens on Mr. Thomson’s farm.
Mr. Thomson adds 6 more geese and 3 more hens to his farm.
Than
The number of geese becomes = 6 + 6
= 12
The number of hens becomes = 9 +3
= 12
The new ratio of the number of geese to the number of hens be
simplify
Therefore the new ratio of the number of geese to the number of hens be 1:1 .
Answer:
x = 14, y= -3
Step-by-step explanation:
Solve the following system:
{2 x + 8 y = 4 | (equation 1)
{x = 5 - 3 y | (equation 2)
Express the system in standard form:
{2 x + 8 y = 4 | (equation 1)
{x + 3 y = 5 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{2 x + 8 y = 4 | (equation 1)
{0 x - y = 3 | (equation 2)
Divide equation 1 by 2:
{x + 4 y = 2 | (equation 1)
{0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{x + 4 y = 2 | (equation 1)
{0 x+y = -3 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{x+0 y = 14 | (equation 1)
{0 x+y = -3 | (equation 2)
Collect results:
Answer: x = 14, y = -3
y=8x-[1+4x]
