Manuel thinks that the temperature will decrease by -1.3 degrees per week for the next 12 weeks. If the temperature today is 52 degrees, what would the temperature be 12 weeks from now?

The temperature will be 36.4 degrees.

Step-by-step explanation:

Hi, to answer this question we have to subtract the product of the temperature decrease per week (-1.3) and the number of weeks (12) to the actual temperature (52).

Mathematically speaking:

52 - (1.3 x 12)  

Solving:

52-15.6

36.4 degrees

The temperature will be 36.4 degrees.

(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
