2/3x + 4 = 3/5x - 2 6 - .25x = x - 3

3(x-4) = -1/2(24-6x)

5x=20(4 + .25x)

Plsss answer these four questionss

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

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
