Answer 1

Answer:

Answer:

n = -10

Step-by-step explanation:

solving a one step equation with a missing variable

step 1: subtract 3 from both sides of the equation then simplify

ex: n + 3 - 3 = -7 - 3 (n = -10)

step 2: take your answer of n which is -10 and add plug it in into your original equation n + 3 = -7 and solve to check your answer

ex: n + 3 = -7 (-10 + 3 = -7)

add

-10 + 3 = -7

-7 = -7 (if both sides of the equation are the same numbers like -7 = -7 then your answer is true making n = -10 your answer) i would love to get brain if this is correct and helps <(^w^)>

use this and the formula for sn to find the total cost of tution and fees at public colleges for four years

Answers

Just substitute 4 in for n, then you would get 395*4 +5419. That is 6999, so it's 6999 for four years.

$\boxed{a_n=395n+5419}\n \n a_4=395*4+5419\n \n a_4=1580+5419\n \n \boxed{\boxed{a_4=6,999}}$
