Question number 10 is the same as the previous questions add them up and make them equal to 180 degrees, and then solve for the x variable.
For the second part of the question, simply plug in the value of x for each expression for R and S.
Answer:
-6/13
Step-by-step explanation:
It can’t be determined because there is too many numbers
Answer:
The only problem was that now it costs more so not really
Step-by-step explanation:
I think its an opinion question
<em><u>Question:</u></em>
If y varies inversely with the square of r, what is the constant of proportionality when y =10 and r = 5?
<em><u>Answer:</u></em>
The constant of proportionality is 250
<em><u>Solution:</u></em>
Given that,
y varies inversely with the square of r
Which means,

Where, "k" is constant of proportionality
Subtitute y = 10 and r = 5

Thus the constant of proportionality is 250
