10 points + brainliest to first correect answer :) incorrect answers/ answers with no effort will be deleted this is easy im just making sure :) The temperature in Mariah’s town was 5.2 degrees Fahrenheit at midnight. The temperature decreased at a steady rate of 1.1 degrees Fahrenheit per hour until 7:00 a. m. From 7:00 a. m. through noon, the temperature increased by a total of 4.9 degrees Fahrenheit. What was the temperature at noon?

a- Negative 7.4 degrees Fahrenheit
b- Negative 2.5 degrees Fahrenheit
c- 2.4 degrees Fahrenheit
d- 7.4 degrees Fahrenheit

C. 2.4 degrees Fahrenheit

Step-by-step explanation:

1.1 per hour for 7 hours

1.1 x 7 = 7.7

5.2 - 7.7= -2.5

-2.5 + 4.9 = 2.4

(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
