Answer:

[tex]x=-\frac{5}{3}\quad \mathrm{or}\quad \:x=3[/tex]

Step-by-step explanation:

[tex]2\left|3x-2\right|=14[/tex]

⇒ Divide both sides by 2

[tex]\frac{2\left|3x-2\right|}{2}=\frac{14}{2}[/tex]

[tex]\left|3x-2\right|=7[/tex]

⇒ Now, apply absolute rule:- if |x|=a,a > a than x=a or x=-a

[tex]3x-2=-7\quad[/tex]

or...

[tex]3x-2=7[/tex]

Now,

[tex]3x-2=-7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=-7+2[/tex]

[tex]3x=-5[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{-5}{3}[/tex]

[tex]x=-\frac{5}{3}[/tex]

[tex]3x-2=7[/tex]

⇒ Add 2 to both sides:-

[tex]3x-2+2=7+2[/tex]

[tex]3x=9[/tex]

⇒ Divide both sides by 3:-

[tex]\frac{3x}{3}=\frac{9}{3}[/tex]

[tex]x=3[/tex]

Measuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second.

What increase in the speed of sound is caused by a 4-kilometer increase in depth?

Answers

Step-by-step explanation:

speed of sound in x depth = 1534 + 17x

4 × 17 = 68 is the increase of sound speed caused by 4 km increase in depth

4.25x10 to the power of 3 in standard notation

Answers

The basic idea is that multiplying by 10 just moves the decimal point one place to the right.  It makes the number bigger.

Examples:

3.1 x 10 = 31

3.1 x 10 x 10 = 31 x 10 = 310

Each time you multiply by another 10, the decimal point moves one more place.

In your exercise, [tex]10^3[/tex] says you're going to multiply by 10 three times in a row.  So that will move the decimal point 3 places to the right.

So what do you get if you move the decimal in 4.25 three places to the right?

#2

b + 3/2b + b + 45 + 2b - 5 + 90 = 540

b + 1.5b + b + 45 + 2b - 5 + 90 = 540

5.5b = 540 - 130

5.5b = 410

b = 410/5.5

b = 74.5

What is the common difference of the following sequence? 27, 11, -5, -21, -37, . . .

Answers

Answer:

Find the common difference and the next term of the following sequence:

3, 11, 19, 27, 35...

Step 1. To find the common difference, subtract any consecutive pair of terms.

11 - 3 = 8

19 - 11 = 8

27 - 19 = 8

35 - 27 = 8

The difference is always 8, so d = 8.

Step 2. Use the common difference to find the next term.

Since the last term was 35, adding the common difference of 8 will find the next term. The next term is 35 + 8 or 43.

Step-by-step explanation:

Answer:

Consider the given line segment. If AC is 39cm long, answer the following questions:
A
B
9x+7
-3x+20
AB -
BC =
Is point B the midpoint? (yes or no)

Answers

The point which is equidistant from the endpoints of a line segment, hence, marking the middle point of the line is called the midpoint. Therefore, Point B is not the midpoint

AB + BC = AC

9x + 7 + (-3x + 20) = 39

9x + 7 - 3x + 20 = 39

6x + 27 = 39

6x = 39 - 27

6x = 12

x = 12 / 6

x = 2

9x + 7 = - 3x + 20

9(2) + 7 = - 3(2) + 20

25 = 15

Hence,

Since, AB ≠ BC, then B is not the midpoint
