To solve this, you need to isolate/get the variable "n" by itself in the equation:
Multiply 21 on both sides to get "n" by itself
Simplify the fraction
-18 = n
Answer:
One solution.
Step-by-step explanation:
X=2/3 or x=2.6666
Answer:
Step any explanation:
t & 1/r
t = k/r
When t =6 and r = 5
k = tr
k = 6×5
k = 30
Constant of proportionality is equal 30
c and e are expressions.
b is an equation.
a and d are inequalities.
Expressions are the only ones WITHOUT an 'equals', 'greater', or 'less than'.
