Answer:
Step-by-step explanation:
Remark
Since the chords of the circle are equal and non intersecting, The 2 bisecting perpendiculars are going to be equal.
Equation
5x = 7x - 8 Subtract 7x from both sides
5x - 7x = - 8
-2x = - 8 Divide by - 2
x = - 8/-2
x = 5
I would say the simplified form would be 20×10^-7
If the rate at which the temperature fell is 4/5 degree/hour then we can simply multiply 5 hours to get our answer.
4/5 * 5/1 = 20/5 = 4
So, it would change a total of 4 degrees.
I hope this helps. If something is confusing or this answer is wrong, don't be afraid to drop me a DM telling me what is wrong.
If I answer can I have brainliest answer plz
