At 3pm, the temperature outside was 5 1/5 degrees fahrenheit. the temperature then fell steadily by 2 1/2 degrees per hour for the next four hours. what was the temperature at 7pm? plz answer this and i will give you 100 points plz

-4 4/5 deg F

Step-by-step explanation:

3 pm: 5 1/5 deg

2 1/2 deg per hour for 4 hours = 2 1/2 deg * 4 = 10 deg

7 pm: 5 1/5 deg - 10 deg = -4 4/5 deg

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
