Which expression has a value of 15 when n=7 ?

answer a isnt it because 5n -43 is 14

           b isnt it because 3n + 5 is 32

           c isnt it because 6n - 28 is 39

so the only possible answer is d 19 -28/7

28/7 = 4 because 28 goes into 7 4 times so that would be 19 - 4, 9 - 4 = 5, so just bring the 1 down from 19 and it would equal 15

I really hope this helped if it did please let me know and if i am right can i please have brainliest answer the reason i know the answer choices is because i did not get the answer from another question but i could not answer that persons question because 2 people were already answering so i looked up the question on and they had a picture of the answer choices and so i looked at the math problems that were the answer choices and i did the math then looked up the question by the time i was about to answer the 2 people hadn't answered yet but the were already answering it so i could not answer their question.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
