PWEASE HELP:)The difference between a number and three is multiplied by negative six. The result is eighteen. What is the number? Write an equation that can be used to find the number, .
Solve the equation you wrote in part A to find the value of the number. Include all of your work in your answer.

Step-by-step explanation:

x-3x-6 this is the equation solve it

0

Step-by-step explanation:

Let the unknown number be ‘a’

a - 3 x (-6) = 18

a + 18 = 18

subtract 18 on both sides

a = 0

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

hope it you

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
