6(x - 8) = 96

Answers

Answer:

x= 24

Step-by-step explanation:

Multiply each term in the parentheses. Not sure if this helps but I hope it does.

6(x−8)=96

(6)(x)+(6)(−8)=96(Distribute)

6x+−48=96

6x−48=96

Step 2: Add 48 to both sides.

6x−48+48=96+48

6x=144

Step 3: Divide both sides by 6.

Step-by-step explanation:

Which number is greater,
23×10^3
or
11×10^4?

How do you know? Explain your steps.

Answers

the greater number would be 11•10^4

to know this, you have to evaluate each equation and compare your answers.

10^3 = 1,000
23•1,000 = 23,000

10^4 = 10,000
11•10,000 = 110,000

110,000 > 23,000

(hope this helps some)

[tex]11\times 10^4[/tex] is the greater number among the given.

The given numbers are 23×10³ and [tex]11\times 10^4[/tex].

We need to identify which is the greater number among the given.

What is scientific notation?

The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.

Now, 23×10³=23×1000=23000 and [tex]11\times 10^4[/tex]=11×10000=110000

Therefore,  [tex]11\times 10^4[/tex] is the greater number among the given.

...............times larger in area than the Southern Ocean.

Answers

Answer: A. 8

Step-by-step explanation:

An elevator travels 310 feet in 10 seconds. At that speed, how far can this elevator travel in 12 seconds?

Answers

Answer:

372 feet

Step-by-step explanation:

We need to first figure out how fast it goes per second

310 / 10 = 31.

31 x 12 = 372 feet.

That is one fast elevator

Answer:372

Step-by-step explanation:

310/10=31

31*12=372

One of the rows in the table has an error and does not have the same ratio as the other rows.

Row 2

Row 3
7
94
Row 4

108

Which explains how to correct the error in the table?
Row 1 should show 3 feet is equivalent to 32 inches.
Row 2 should show 6 feet is equivalent to 66 inches.
Row 3 should show 7 feet is equivalent to 84 inches.
Row 4 should show 9 feet is equivalent to 104 inches.

Answers

Answer:

Row 3 should show 7 feet is equivalent to 84 inches.

Step-by-step explanation:

First divide 36 and 3 to find the constant proportion. Which you get 12

Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9

You should be able to find the incorrect answer which is row 3

12 x 7 actually equals 84 not 94

Hope this makes sense!

If you know US Customary, you will recognize that in each foot, there is 12 inches. Answer a: 12(3) is equal to 36, 12(6) is equal to 72, and 12(9) is equal to 108. Through the process of elimination, Row 3 should not be 94 inches = 7 feet; it would be 84 inches. Hope this helps!
