Answer:
(x, y) = (77/240, -3/10)
Step-by-step explanation:
It is convenient to write the equations in standard form.
Multiplying the first equation by 21 gives ...
21y = 24x -14
Multiplying the second equation by 8 gives ...
24x +9y = 5
Then the system of equations in standard form is ...
Subtracting the first from the second, we get ...
(24x +9y) -(24x -21y) = (5) -(14)
30y = -9
y = -9/30 = -3/10
Substituting this into the second equation, we have ...
24x +9(-3/10) = 5
24x = 7.7 . . . . . . . add 27/10
x = 7.7/24 = 77/240
The solution is (x, y) = (77/240, -3/10).
When finding the mean you should first add up all the numbers which are 12,2,8,6 and 57 which will give you a sum of 85 next you should divide your sum by how many numbers there are which is 5 and your answer should be 17
Well you would start at Y= 0(-x) -2. So (0, -2) then you would move to the left by 1 and move down by 1.
Answer:
14 spotted socks
Step-by-step explanation:
Sam has 3 units of striped socks and 6 of them.
Find one unit.
3 units = 6
1 unit = 6 ÷ 3 = 2
Sam has 7 units of spotted socks.
7 units = 2 x 7 = 14
