X= -y + 1/2z+ -19/2
Hope it helps
Answer:
Three angles measuring 75, 45, and 60.
Step-by-step explanation:
The rates are equivalent because both of them do 30 jumping jacks a minute.
Ex: y=2x+4 <span>3x+y=9 <--Simply plug y into the second equation here and solve for x. When you find the solution for x, you can plug the solution to x into the 2nd equation to find y....Hope this helps!!!</span>
Answer: this is our required factor i.e.

Explanation:
Since we have given that

As we know the identity , which says that

So, we can use this here ,

Hence this is our required factor i.e.
