Three times a number is three more than twice the number. which equation can be used to find the value of x, the unknown number? 3x = 3 + 2x x = 3 + 2x 3x + 3 = 2x x + 3 = 2x

We have to find the equation for three times a number is three more than twice the number.

Let the number is x.

Three times a number = 3x

Three more than twice the number. = 3+2x

These two equations should be equal.

Hence, we have

Therefore, the equation 3x = 3 + 2x can be used to find the unknown x.

A is the correct option.

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
