The tempature was very cold, tgen it doubled, then it dropped 10 degrees, and then it increased by 40 degrees. The tempature is now 16 degrees. What was the starting tempature?

Answer

The initial temperature was T = -7 degrees

Step-by-step explanation:

Let the initial temperature be T.

- The tempature was very cold

Temperarure = T

- Then it doubled

Temperature = 2T

- Then it dropped 10 degrees

Temperature = 2T - 10

- And then it increased by 40 degrees.

Temperature = 2T - 10 + 40 = 2T + 30

The tempature is now 16 degrees

Temperature = 16 degrees

2T + 30 = 16

2T = -14

T = -7 degrees

Hope this Helps!!!

The starting temperature was -7 degrees

Step-by-step explanation:

Let's call the inicial temperature by 'X'.

First the temperature doubled, so now it is 2X.

Then, it dropped 10 degrees, so now it is 2X - 10

Then, it increased by 40 degrees, so now it is 2X - 10 + 40 = 2X + 30

Now, the temperature is 16 degrees, so we have that:

2X + 30 = 16

2X = 16 - 30

2X = -14

X = -7

The starting temperature was -7 degrees

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
