1. Add 4x back into -2, you now have -4y=-4x-2. Add +4 from y and now you are at y=-4x+2 and this is the answer!
2. Add -9x back into -3, you now have -4y=9x-3. Add +4 from y and now you are at y=9x-7 and this is your answer!!
I hope this helped! Brainliest? :) -Raven❤️

its correct bro ;) click next
Combine like terms
8u+3u= 11u
and
9v-5v= 4v
So the answer is 11u+4v
Well, if 224,988 pounds of milk is produced by 12 cows, if i divide 224,988 by 12 i get the pounds per 1 cow. Consider it set up in this ratio.
224,988pounds/12 cows = xpounds/1 cow
Then you would solve for x.

Answer:

Step-by-step explanation:
Given,
Art electives = 3,
History electives = 4,
Computer electives = 5,
Total number of electives = 3 + 4 + 5 = 12,
Since, if a student chooses an art elective and a history elective,
So, the total combination of choosing an art elective and a history elective = 
Also, the total combination of choosing any 2 subjects out of 12 subjects = 
Hence, the probability that a student chooses an art elective and a history elective = 

Which is the required expression.
