"Solve for x" means get an equation that says " X = something ". It has nothing but X all alone on one side, and the other side tells exactly what X is equal to.

How do you get such an equation ?

-- Take what they gave you in the question.

-- Do anything you want on one side of it, to get X all by itself on that side.

-- Whatever you do to one side, you must immediately do the same thing on the other side.

Here's how that goes:

Given in the question: -1 = (5 + X) / 6

Multiply each side by 6 : -6 = 5 + X

Subtract 5 from each side: <em>-11 = X</em>

And there you are. It's over almost as soon as it started.

Anastaziya [24]

Step-by-step explanation:

Given that:-

1 cell = 15 minutes

So, we can concert 15 minutes to hours.

So,

60 minutes = 1 hour

1 minute = 1/60

15 minutes =

$\frac{15}{60} = 0.25 \: hrs$

Okay, now we will apply first for 0.4 hours.

$0.25 \: hrs= 1 \: cell$

$1 \: hr = \frac{1}{0.25}$

$0.4 \: hrs = \frac{0.4}{0.25}$

$= 1.6 \: cells$

$= 16 \times {10}^{ - 1} \: cells$

Now, second one:-

$10 \: hrs = \frac{10}{0.25}$

$= 40 \: cells$

$= 0.4 \times {10}^{2} \: cells$

Hope it helps :D
