Which variable expression represents the phrase “the sum of a number and 10”? 10n n−10 n÷10 n + 10

let the given number is n

sum means use add (+) sign.

then sum of a number and 10 can be written as (n+10)

Hence (n+10) is the final answer.

Since each answer is 10 using a different action, here is what each one will give you.

Addition gives a sum. subtraction gives a difference, division gives a quotient and multiplication gives a product. It is asking for a sum, so which uses addition.

8121 because

130,000 divided by 16 is 8121

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
