What are the steps to solving 2x+4=6x-12

4

Step-by-step explanation:

Step 1:

2x + 4 = 6x - 12        Equation

Step 2:

4 = 4x - 12        Subtract 4x on both sides

Step 3:

16 = 4x        Add 12 on both sides

Step 4:

x = 16 ÷ 4        Divide

x = 4

Hope This Helps :)

x = 4

Step-by-step explanation:

Solve for x:

2 x + 4 = 6 x - 12

Subtract 6 x from both sides:

(2 x - 6 x) + 4 = (6 x - 6 x) - 12

2 x - 6 x = -4 x:

-4 x + 4 = (6 x - 6 x) - 12

6 x - 6 x = 0:

4 - 4 x = -12

Subtract 4 from both sides:

(4 - 4) - 4 x = -4 - 12

4 - 4 = 0:

-4 x = -4 - 12

-4 - 12 = -16:

-4 x = -16

Divide both sides of -4 x = -16 by -4:

(-4 x)/(-4) = (-16)/(-4)

(-4)/(-4) = 1:

x = (-16)/(-4)

The gcd of -16 and -4 is -4, so (-16)/(-4) = (-4×4)/(-4×1) = (-4)/(-4)×4 = 4:

x = 4

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
