(a)A tram moved downward 20 meters in 4 seconds at a constant rate. What was the change in the tram's elevation each second? (b)In a lab, a substance was heated by 4 degrees Celcius each hour for 36 hours. What was the total change in temperature?

26

step-by-step explanation:

pretty sure 750 each month!

step-by-step explanation:

(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
