Six less than twice a number, x, is 38. what is the value of x

If six less than twice a number, x, is 38, then the value of x will be 21

Let the unknown number be x

Twice the number x is expressed as 2x

six less than twice a number, x will be expressed as 2x - 6

If the result is equal to 36, this will be written as 2x - 6 = 36

Solve the resulting equation

2x - 6 = 36

Add 6 to both sides

2x - 6 + 6 = 36 + 6

2x = 42

x = 42/2

x = 21

Hence if six less than twice a number, x, is 38, then the value of x will be 21.

Step-by-step explanation:

2x-6=38

2x=38+6

2x=44

x=44/2

x=22

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
