Answer:  x = 2

<u>Step-by-step explanation:</u>

10 - 2(2x + 1) = 4(x - 2)

10 - 4x - 2 = 4x - 8       <em>distributed -2 into 2x + 1 and 4 into x - 2</em>

8 - 4x = 4x - 8             <em>added like terms (10 - 2 = 8) on left side</em>

8        = 8x - 8             <em>added 4x to both sides</em>

16       = 8x                  <em>added  8 to both sides</em>

2        =  x                   <em>divided 8 from both sides</em>

Answer:

No solution

Step-by-step explanation:

Actually, you have only one equation here.  We will solve it for x.

Performing the indicated multiplication, we obtain:

10-2(2x+1)=4(x-2)  =>  10 - 4x - 2 = 4x - 8, or 10 - 2 = -8.  This can never be true, so this equation has no solution.

.A bacteria culture grows at a rate of 20%
Zolol [24]

The number of the specimens would be in the culture after 5 minutes will be 7,962.62.

<h3>What is an exponent?</h3>

Consider the function:

y = a (1 + r) ˣ

Where x is the number of times this growth occurs, a = initial amount, and r = fraction by which this growth occurs.

A bacteria culture grows at a rate of 20% per minute.

If the culture initially has 3,200 bacteria specimens.

Then the equation will be

y = 3200 (1 + 0.2) ˣ

y = 3200 (1.20) ˣ

Then the number of the specimens would be in the culture after 5 minutes will be

y = 3200 (1.20)⁵

y = 7962.62

More about the exponent link is given below.
