Answer:

Answer: 5x - 9 = 6

Step-by-step explanation:

x = 3

2(3) - 8 -= 5 --> 6 - 8 =5  (false)

9(3) + 4 = -31 --> 27 + 4 = -31 (false)

6(3) - 9 = 57 --> 18 - 9 = 57 (false)

5(3) - 9 = 6 --> 15 - 9 = 6 (true)

Answer:

5x-9 =  6

Step-by-step explanation:

5x−9=6

Add 9 to both sides.

5x=6+9

Add 6 and 9 to get 15.

5x=15

Divide both sides by 5.

x=  15/5

Divide 15 by 5 to get 3.

x=3

Scientists found that a certain particle of dust doubles every 30 minutes. If the scientists tests this out with 21 grams of the
monitta

Answer: 1.663\times 10^{30}\ gm

Step-by-step explanation:

Given

Population of dust particle doubles every 30 minutes

If the initial sample is 21 grams

The model to predict the population will be

\Rightarrow P=21\cdot 2^{2t}

Where t=time in hours

A day has 24 hours . So, for 2 days time is 48 hours

Population is given by

\Rightarrow P=21\cdot 2^{2\times 48}\\\\\Rightarrow P=21\times 2^{96}\\\\\Rightarrow P=1.663\times 10^{30}\ gm

Given the lengths of two sides of a triangle, find the range for the length of the third side. (Range means find between which t
Sidana [21]
<h3>Answer:  5 < x < 21</h3>

Explanation:

Let x be the length of the third side. We can't find the exact value of x, as we don't have enough info, but we can find possible values for x.

The lower boundary for x is 13-8 = 5. It must be larger than this value.

At the same time, x must be smaller than 13+8 = 21 as well.

So x > 5 and x < 21 becomes 5 < x < 21

In short, x is between 5 and 21. It cannot equal either endpoint.
