Answer:

Solve for X ( The question I did was an example )

Step-by-step explanation:

To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.

2x=21

Now the next step is to divide. You have to divide to get the answer.

If an airplane descends 15 feet every 1.45 seconds, how far would the airplane travel in three and a half minutes? The equation

NemiM [27]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Here we go ~

The air plane descends 15 feels every 1.45 seconds, so it's unit rate is :

$\qquad \sf \dashrightarrow \: \dfrac{15}{1.45} \: \: ft / sec$

Now we have to calculate the descent in 3.5 minutes ~

$\qquad \sf \dashrightarrow \: \dfrac{15}{1.45} \: \: \times 3.5 \times 60$

$\qquad \sf \dashrightarrow \: 2172.41 \: \: ft$

So, the airplane descends 2172.41 feels in three and a half minutes ~
