Casey has n nickels. megan has 4 times as many nickels as casey has. write an expression for the total number of nickels casey and megan have. then simplify the expression.

n = number of nickels casey has

n is simply a placeholder for a number

4*n = number of nickels Megan has

whatever number Casey has, multiply it by 4 to get Megan's number

We add n and 4n to get 5n. We can think of it as 1n+4n = (1+4)n = 5n

Or we can think of it as 1 nickel + 4 nickels = 5 nickels

The final simplified expression is 5n

∡ eia and ∡ kij are congruent
