The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. write an equation that could be used to find how many ounces a letter that costs $0.93 weighs. (let x represent the number of ounces.)
0.59x = 0.93 0.42x + 0.17 = 0.93 0.59 = 0.93x 0.42 + 0.17x = 0.93

0.42 + 0.17x = 0.93

Step-by-step explanation:

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 will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
