Solve each equation. Explain your method.8.88=4.44(x−7)

omeli [17]

8.88=4.44(x−7)

write the equation

8.88 - 4.44=(x−7)

Transfer 4.44 to other side and it's sign changes from positive to negative

4.44=(x−7)

After subtracting we will get result as 4.44

(x−7) = 4.44

Arrange the equation as variable always comes at left side.

x−7 = 4.44

open brakets

x = 4.44 + 7

transfer 7 to other side and it changes from - to + sign

x = 11.44

The function y = -3x + 5 is transformed by reflecting it over the y axis. What is the equation of the new function? *

SpyIntel [72]

Answer:

x= −1/3 y+5/3

Step-by-step explanation:

Let's solve for x.

y=−3x+5

Step 1: Flip the equation.

−3x+5=y

Step 2: Add -5 to both sides.

−3x+5+−5=y+−5

−3x=y−5

Step 3: Divide both sides by -3.

−3x

The assumptions made are: The gas molecules from Caesar's last breath are now evenly dispersed in the atmosphere. The atmosphere

Dovator [93]

Answer:

$2.6\times 10^{19}m^{3}$

Step-by-step explanation:

we have given thickness of atmosphere =50 km

radius of earth =6400 km

average temperature of atmosphere=15°C

Average pressure of atmosphere= 0.20 atm

we have to calculate the volume of atmosphere

so the we have to calculate the volume of atmosphere = ( volume of earth +atmosphere) - volume of earth

volume of atmosphere = $\frac{4}{3}\times\pi \times \left ( 6400+50 \right )^{3}-\frac{4}{3}\times \pi\times 6400^3$

= $2.6\times 10^{19}m^{3}$
