What is 0.40x+10=45 in math

x=87.5

Step-by-step explanation:

I'm pretty sure they ask you to solve for x. So you need to make x as alone on one side. To do that, I will move +10 to other side by subtracting by 10 for both sides. 0.40x=35. Now, we need to solve for x. So x must be 1. To do that, I will divide 0.40 for both sides which gives you the answer. x=87.5

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

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
