I hope you meant find x
5x + 3x + 2x = 180. x=18

The answer is 9528.128
Step-by-step explanation:
Sorry, I don't know that as a fraction
If you have a graphing calculator, you can simply type it into y= and it will graph it for you. But if you need coordinates, the line runs through (0,2) , (4,5) , and (-4,1)
Answer:
Step-by-step explanation:
So we have direct proportions here.
So
715=11
845=x
845*11/715
x=13
To check our work.
715/11=65
65*13=845.
Basically, in this formula, you use cross multiplication. So A*B=B*A. B and B go together and A and A go together/
So we can use the formula x = b*b/a. Since A is one of the A's and the other value of A is missing, we can use this formula to find it.
Hope this helped, ask me if you have any questions.
9)=A These two are indications of a chemical change. (I am positive it is A)
10)=A It is not D and the others don't seem as right so I hope this helps.
