Answer:

add x to both sides
divide both sides by 4
add 20 to both sides
divide both sides by 3

Step-by-step explanation:

Your steps in order would be ...

add x to both sides
divide both sides by 4
add 20 to both sides
divide both sides by 3

Executing these steps, we get ...

4(3x -20) = 16 . . . . . add x

3x -20 = 4 . . . . . . . . divide by 4

3x = 24 . . . . . . . . . . .add 20

x = 8 . . . . . . . . . . . . . divide by 3, giving the solution

Additional comment

If you were to distribute the 4 first, you would have ...

12x -80 -x = 16 -x

Now, you can add x and add 80 to get ...

12x -80 = 16

12x = 96

Then dividing by 12 gives ...

x = 8

You will notice that these steps do not match steps available in your list.

Distribute 4 to get 12x-20
Add x to both sides
Add 20 to both sides
Divide both sides by 12

A chemical flows into a storage tank at a rate of (180+3t) liters per minute, where t is the time in minutes and 0<=t<=60

Yuliya22 [10]

Answer:

The amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.

Step-by-step explanation:

Consider the provided information.

A chemical flows into a storage tank at a rate of (180+3t) liters per minute,

Let $c(t)$ is the amount of chemical in the take at t time.

Now find the rate of change of chemical flow during the first 20 minutes.

$\int\limits^{20}_{0} {c'(t)} \, dt =\int\limits^{20}_0 {(180+3t)} \, dt$

$\int\limits^{20}_{0} {c'(t)} \, dt =\left[180t+\dfrac{3}{2}t^2\right]^{20}_0$

$\int\limits^{20}_{0} {c'(t)} \, dt =3600+600$

$\int\limits^{20}_{0} {c'(t)} \, dt =4200$

So, the amount of the chemical flows into the tank during the firs 20 minutes is 4200 liters.
