Here are the original equations:
2x + 2y = 14
x + 2y = 11
We immediately note that these two equations form a system. So, we can use substitution to solve the second equation for x. To do this, all that needs to be done is to subtract 2y from both sides, to get x = 11 - 2y. Next, we substitute the derived expression for x into the first equation to get 2(11-2y) + 2y = 14. We can use the distribute property to get 22 - 4y + 2y = 14. Then, we can combine like terms to get 22 - 2y = 14. After that, we subtract 22 from both sides to get -2y = -8. Finally, we divide -2 from both sides to get y = 4.
Now that we have the value for y, we can substitute our derived value into the second equation, since it will be much faster. After doing this, we get x + 2(4) = 11. We can simplify the left side of the equation and subtract the product from both sides, which gives us x = 4. Therefore, the answer to your query is x = 4, y = 4. Hope this helps and happy Halloween!
Given the following question:
Lable all the sides of the triangle:
Hypotenuse is the missing side
Right angle is the opposite
Adjacent is equal to 21
We have all of our sides so now we won't get them mixed up when finding the missing value of this triangle.
sin =
opp/hyp
cos =
adj/hyp
tan =
opp/adj
Since we are given the adjacent side and we are trying to find the hypotenuse we will solve for cos since we have the adjacent side but we need the hypotenuse
cos(35)=21/x
Now solve:

Answer:
There are 64 chickens
Step-by-step explanation:
60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64
