What is an expression?

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

given that,

the expression is : 3x– 2

now, we have to find the expression which is not equivalent to 3x– 2.

now, we have, from the given options:

1.) x+x-1-1+x

= 3x - 2 , which is equivalent to 3x– 2.

2.) 2x+ 2+x

= 3x + 2 , which is not equivalent to 3x– 2.

3.) 3-x+ 2x-5 + 2x

= 3x - 2, which is equivalent to 3x– 2.

4.) 4x- 4-x+2

= 3x - 2, which is equivalent to 3x– 2.

Hence, The solution is, 2x+ 2+x, is the expression which is not equivalent to 3x– 2.

The expression 8x + 12y represents the sum of Harry's and Lloyd's total wages, where x represents the number of hours Harry worked and y represents the number of hours Lloyd worked. What is another way to write the expression, and what can you conclude from rewriting it in this way?

Answers

Answer:

The rewritten is x + 1.5y.

It can be concluded that Lloyd earns $0.5 per hour more than Harry.

Step-by-step explanation:

Given;

8x + 12y

The expression can be rewritten by dividing it through by 8 as follows:

(8 / 8)x + (12 / 8)y = x + 1.5y

Therefore, the expression can be rewritten as x + 1.5y.

Since x represents the number of hours Harry worked and y represents the number of hours Lloyd worked, the new expression implies that Harry earns $1 per hour while and Lloyd earns $1.5 per hour. Therefore, it can be concluded that Lloyd earns $0.5 per hour more than Harry.

Value of Term 9
10 11 12 13

Answers

Answer:

[tex]a_n=n+9[/tex][tex]a_9=18[/tex]

Step-by-step explanation:

Determining the expression for the sequence:

Given the sequence

10,  11,  12,  13

Here, the first element is:

a₁ = 10

An arithmetic sequence has a constant difference 'd' and is defined by  

[tex]a_n=a_1+\left(n-1\right)d[/tex]

computing the differences of all the adjacent terms

[tex]11-10=1,\:\quad \:12-11=1,\:\quad \:13-12=1[/tex]

The difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

now substituting d = 1 and a₁ = 10 in the nth term

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+10[/tex]

[tex]a_n=n+9[/tex]

Determining the value of the 9th term

Given the nth term

[tex]a_n=n+9[/tex]

substituting n = 9 to determine the 9th term

[tex]a_9=9+9[/tex]

[tex]a_9=18[/tex]

Therefore, the vale of the 9th term is:

[tex]a_9=18[/tex]

Please helpz Your friend evaluates (12 + x) ÷ 6 for x = 6 and gets 13. Explain your friend's error.

Answers

Answer:

See explanation

Step-by-step explanation:

The correct answer is obviously 3 because if we substitute x = 6 into the expression we get ( 12 + 6 ) / 6. Using the order of operations, we get 18 / 6 = 3.

The friend likely didn't use the order of operations when evaluating. It's most likely that he substituted x = 6 into the expression and got ( 12 + 6 ) / 6. Instead of first adding 12 and 6, he divided 6 by 6 first to get 1, then added 12 to get 13.

Answers

Answer:

12 hours and 4 minutes

Step-by-step explanation:

To solve first convert both terms to minutes. Do this by multiplying the number of hours by 60, then adding the remaining minutes. 8*60=480, then 480+39=519 minutes. Next, convert 3 hours and 25 minutes to 205 minutes. So now we have 519 minutes and 205 minutes, so add those together to get 724 minutes. Finally, convert back to hours to 12 hours and 4 minutes by dividing by 60.
