I will name Brainliest. I give my thxs ahead of time. Please Show your work and Solve. What is the answer to these 5 questions?
(1) -X + 4 = -2X - 6
(2) 4R - 4 = 3R + 10
(3) 2Y - 3 = Y - 4
(4) Ryan is X years old. Two times his age plus fifteen equals thirty-seven minus two. Write and equation showing how old Ryan is. Solve if you can.
(5) Andy is two fifths of Ruth's age. Ruth is ten. How old is Andy?

21 i watched a 3 hr vid explaining it

step-by-step explanation:

du what else would it be

brainliest

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

according to egenuity the answer is
