The algebraic expression for the given statement is k-13.

The given statement is "15 less than the sum of k and 2".

We need to form the algebraic expression for the given statement.

In mathematics, an algebraic expression is an expression built up from integer constants, variables, and algebraic operations.

Now, the sum of k and 2=k+2

15 less than the sum of k and 2=(k+2)-15

=k+2-15

=k-13

Therefore, the algebraic expression for the given statement is k-13.

Answer and Step-by-step explanation:

3 x 2 - x = ? Well, if you simplify it's just 5x. But, if you are trying to solve this then you have to know what x is or what your answer is. But, if you're trying to solve 3 x 2 = x then x would equal 6. Of course, if you know the answer or what x equals then plug it in as such, let's say x = 2 then you would plug 2 in for x and solve, 3 x 2 = 6 - 2 = 4. But, if you are trying to solve for x then look at the answer, let's say it is 24 so, 3 x 2 - x = 24, x would equal -18.

Answer:

x=4

Step-by-step explanation:

9=1/4 (6x+12)

Multiply each side by 4

4*9 =4*1/4 (6x+12)

36 =  (6x+12)

Subtract 12 from each side

36-12 = 6x+12-12

24 = 6x

Divide each side by 6

24/6 = 6x/6

4 =x

Sorry I couldn't help with the rest! Goodluck!~

Answer:

d. 20(x)+3(2x)=138

ap3x

The number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3.

A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.

Now it is given that,

Cost of each softball , $3.

Cost of each gloves, $20 .

Total money spend , $138 .

Tax , $8 .

She buys twice as many softballs as gloves.

To Find the number of gloves she buys .

Let , x represent the number of gloves she buys.

So , number of softballs she buys is 2x .

20 (2x) + 3 (x) + 8 = 138

or, 40x + 3x + 8 = 138

or, 43x + 8 = 138

Subtract 8 both the side we get,

43x = 130

or, x = 3.02

0r, x = 3

Hence,the number of gloves she buys is B. 20 (2x) + 3 (x) + 8 = 138, where x = 3

Answer:

2 • (x - 6) • (3x + 2)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x2" was replaced by "x^2".

STEP 1 : Equation at the end of step 1

((2•3x2) - 32x) - 24

STEP 2 : Pulling out like terms

Pull out like factors :

6x2 - 32x - 24 = 2 • (3x2 - 16x - 12)

Trying to factor by splitting the middle term

Factoring 3x2 - 16x - 12

The first term is, 3x2 its coefficient is 3 .

The middle term is, -16x its coefficient is -16 .

The last term, "the constant", is -12

Step-1 : Multiply the coefficient of the first term by the constant 3 • -12 = -36

Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is -16 .

-36 + 1 = -35

-18 + 2 = -16 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -18 and 2

3x2 - 18x + 2x - 12

Step-4 : Add up the first 2 terms, pulling out like factors :

3x • (x-6)

Add up the last 2 terms, pulling out common factors :

2 • (x-6)

Step-5 : Add up the four terms of step 4 :

(3x+2) • (x-6)

Which is the desired factorization

Final result : 2 • (x - 6) • (3x + 2)

Hope this helps~

Answer:

x= - 13

Step-by-step explanation:

2(3x+6) = 3(x-9)

6x+12 = 3x -27

-3x        -3x

3x+12=-27

    -12   -12

3x= -39

/3     /3

x= - 13

Answer:

x = -13

Step-by-step explanation:

2(3x + 6) = 3( x - 9)​

Distribute

6x +12 = 3x - 27

Subtract 3x from each side

6x-3x+12 = 3x-27-3x

3x+12 = -27

Subtract 12 from each side

3x+12-12 = -27-12

3x = -39

Divide by 3

3x/3 = -39/3

x = -13

If c – a = b, then true statement is A. a + b = c

The commutative property states that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer.

Now the given statement is,

c – a = b

adding a to both the the side

c – a + a = b + a

⇒ c = b + a

Using commutative property of addition we get,

a + b = b + a

Therefore, we get

⇒ c = a + b

Thus the true statement is A. a + b = c
