There is no attached picture, but I guess it is like the one I attached.
If so, the first thing is finding the side measure:

Now, radius is half this measure: 15 in.
And circle area is:
Answer:
55.5F
Step-by-step explanation:
y = mx + b
m = slope = -3.5/1000
distance = x = 1000
b = temperature at x = 0 = 59F according to https://www.universalweather.com/blog/international-standard-atmosphere-how-it-affects-flight-understanding-the-basics/
temperature = y = ?
y = -.0035(1000) + 59
y = 55.5
Answer:
J = -2
Step-by-step explanation:
You must isolate the variable by dividing each side by factors that dont contain the variable.
So J would equal -2
