1. write an algebraic phrase for this verbal expression.

4 less than five times a number

2. -3.2 + (-4.6) + 5.4 = ? ?

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

think the answer would beb

i believe it's a.

i'm not sure on this one, most likely correct.
