The given system of equations models the coins in a jar containing n nickels, d dimes, and q quarters. which statement is modeled by one of the equations in the system?

"There are a total of 36 coins in the jar" -- third option

Step-by-step explanation:

First answer choice is wrong (look at meaning of first equation)

Second answer choice is also wrong (look at meaning of second equation)

Third answer choice is correct as it matches the third equation.

Fourth answer choice is wrong since nowhere is says that.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
