Answer:

x = 13.5

Step-by-step explanation:

3(2 x – 5) = 4( x + 3)

Distribute

6x - 15 = 4x +12

Subtract 4x from each side

6x-4x - 15 = 4x-4x +12

2x -15 = 12

Add 15 to each side

2x-15+15 = 12+15

2x = 27

Divide each side by 2

2x/2 =27/2

x = 13.5

Answer:

x = 27/2 = 13.500

Step-by-step explanation:

               

give me brainly please

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    3*(2*x-5)-(4*(x+3))=0

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (3 • (2x - 5)) -  4 • (x + 3)  = 0

Step  2  :

Equation at the end of step  2  :

 3 • (2x - 5) -  4 • (x + 3)  = 0

Step  3  :

Equation at the end of step  3  :

 2x - 27  = 0

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    2x-27 = 0

Add  27  to both sides of the equation :

                     2x = 27

Divide both sides of the equation by 2:

                    x = 27/2 = 13.500

One solution was found :

                  x = 27/2 = 13.500

HELP ASAP!!!!!!!!
Hoochie [10]

Answer:

Step-by-step explanation:

The set {1,2,3,4,5,6} has a total of 6! permutations

a. Of those 6! permutations, 5!=120 begin with 1. So first 120 numbers would contain 1 as the unit digit.

b. The next 120, including the 124th, would begin with  '2'  

 c. Then of the 5! numbers beginning with 2, there are 4!=24 including the 124th number, which have the second digit =1

d. Of these 4! permutations beginning with 21, there are 3!=6 including the 124th permutation which have third digit 3

e. Among these 3! permutations beginning with 213, there are 2 numbers with the fourth digit =4 (121th & 122th), 2 with fourth digit 5 (numbers 123 & 124) and 2 with fourth digit 6 (numbers 125 and 126).

Lastly, of the 2! permutations beginning with 2135, there is one with 5th digit 4 (number 123) and one with 5 digit 6 (number 124).

∴   The 124th number is 213564

Similarly reversing the above procedure we can determine the position of 321546 to be 267th on the list.

Explain why 3(5x) does not equal to (3 times 5)(3times x)
Anit [1.1K]

Answer:

Because 3(5x) is the same as 3 *5 * x

Step-by-step explanation:

When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key

Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.

So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).

Hopefully that makes sense!
