I think the 3rd one, please let me know if I'm wrong. I don't want to give others the incorrect answer.
Step-by-step explanation:
2 x -3 <u>(</u><u>x)</u><u> </u>- 1 <u>(</u><u>y)</u><u> </u>- 2 x -1 <u>(</u><u>z)</u><u> </u>= -5
I believe it's 3/10 but I'm not confident about that.
Answer:
its 6969 because the coefficient is 55 and you have to square it.

Answer:
y = 0.5x
Step-by-step explanation:
Given that x and y vary directly then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition x = 1, y = 0.5, then
k = 
= 
= 0.5, hence
y = 0.5x ← equation of variation
You would start out by putting 225 over 100 then simplifying from there. You would end up getting 9/4. As a mixed number that would be 2 and 1/4.
