{2x-4}{2}=11

Answers

Answer 1

Answer:

x = 19/4

Step-by-step explanation:

(2x - 4)(2) = 11

We can rewrite the equation in a more simple form.

2(2x - 4) = 11

Apply distributive property.

4x - 8 = 11

Get 4x alone. To get 4x alone, add 8 to both sides.

4x - 8 + 8 = 11 + 8

4x = 19

Get x alone. To get x alone, divide both sides by 4.

4/4x = 19/4

x = 19/4

I hope this helps! Let me know if I got anything wrong or if you need any more help.

Answer 2

Step-by-step explanation:

First, you distribute 2 among 2x and -4. This leaves you with 4x - 8 = 11 because when you distribute, you multiply both numbers inside the parenthesis by the number outside of it. Then, you need to eradicate the 8 on the left of the equal sign, so you add 8 to -8 to make it 0, and add 8 to 11 to make it 19. This leaves you with 4x = 19. Finally, you must divide 4x and 19 by 4, leaving you with x = 4.75 or 4¾.

1. (2x - 4)(2) = 11

2. 4x - 8 = 11

3. 4x - 8 + 8 = 11 + 8

4. 4x = 19

5. 4x/4 = 19/4

6. x = 4.75 or 4¾

Responses
A 3939
B 1616
C 3737
D 1313
E 17

Answers

Answer:

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

Mean = 128/8

Mean = 16

16
2+3+5+9+17+22+31+39=128
128/8=16

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

2r-5/4 = 58

I don’t understand what to do next

Answers

Hi

The aim of an equation is  to have  the letter on one side and a value to the pther side of the equal sign.  

For achieving this goal, I can use all operation I know and all quantities I want as long as I do it to each side in the same time. I will make apparent operation in bold.

So :  

2r - 5/4 = 58

if I want 2r  to be alone,  I need to get rid  of  -5/4  

The best way to do that is to add  5/4 to each side as  -5/4 + 5/4 = 0

so

2r -5/4 +5/4  = 58 +5/4

2r +0  = 58 +5/4

now we have :  

2r = 58+5/4

I will caculate the value of  58 +5/4

best way to do that is to convert 58 into  a  fraction .  as 58 *4 = 232  so  58 = 232/4

so now  we  have  :

2r = 232/4 +5/4

2r =  237/4

2r = 59.25

Now we have " 2r " , but my  aim is to have only one " r" .  So we  divide by "2" on each side :

2r /2  =  59.25 /2

r =29.625

If I want to check my result, I exchange the letter by the value I found.  

2 ( 29.625 )  - 5/4 =   59.25 - 5/4  =  59.25 - 1.25 =  58

as 58 is  the value given in line one for   2r - 5/4  , so my result is correct.



Answer:

r = 118.5

Explanation:

Given expression:

\(\sf \dfrac{2r-5}{4} = 58\)

Multiply Both sides by 4

\(\sf \dfrac{2r-5}{4} \times 4 = 58\times 4\)

Doing so gives:

\(\sf 2r-5 = 232\)

Add 5 on both sides

\(\sf 2r-5+5 = 232 + 5\)

Simplify following

\(\sf 2r = 237\)

Dividing Both sides by 2

\(\sf r = 118.5\)

Multiply: 2000x30=?

2000x30=60000

Answer:

52000 pounds

Step-by-step explanation:

On ton is equivalent to 2000 pounds.

We can use this information to set up a unit converter. See the format for a unit converter below:

\(\text{Unit We Have}\ \cdot\ \frac{\text{Unit We Want}}{\text{Unit We Have}}\)

Substitute the given values into the equation:

\(26\text{ tons}\ \cdot\ \frac{2000 \text{ pounds}}{1 \text{ ton}}=26\ \cdot\ 2000 \text{ pounds}=52000 \text{ pounds}\)

The truck weighs about 52000 pounds.

The population of Missoula, MT was 67,358 people in 2010. What was the increase if there were 75,516 people in 2019? What was the average increase per year?

Answers

Answer: 906

Step-by-step explanation:

75,516-67,358= 8,158

2019-2010= 9 years

8,158÷9= 906

The increase in the population is 8158 and average increase in the population per year is 906.4.

What is Subtraction?

Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.

The process of subtraction can also be termed as finding difference.

Given that,

Population of Missoula in 2010 = 67,358

Population of Missoula in 2019 = 75,516

Increase in the population = 75,516 - 67,358 = 8158

Average increase in the population per year = 8158 / (2019 - 2010)

                                                                           = 8158 / 9

                                                                           = 906.4

Hence the increase in the population is 8158 and average increase per year is 906.4.

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8​

Answers

The correct answer is (D) -2x - 8.

To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:

-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3

Then we can simplify using the properties of multiplication and division:

-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3

Finally, we can combine like terms:

-2x - 5 - 3 = -2x - 8

The correct answer is therefore (D) -2x - 8.✅
