Emmett and Charlotte are both selling cookie dough for a fundraiser. Although Emmett has already sold 2 tubs, Charlotte hasn't sold any yet. If Emmett starts selling 7 tubs per day and
Charlotte begins selling 9 tubs per day, they will eventually sell the same amount of cookie
dough. How many tubs will each sell? How many days will that take?

Step-by-step explanation:

7x+2=9x

2=2x

x=1

1 day, they'll each sell 9 tubs

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.
