Marissa has twice as much money as Frank. Christina has $20 more than Marissa. If Christina has $100, how much money does Marissa have?

Marissa has $80

Step-by-step explanation:

are you sure its asking for Marissas money or Franks money? but its fine if its Marissa too

Christina: 100

Marissa: 20 less than her

So 100-20=80

And Marissa has $80

Just in case, heres how to find Franks money:

100-20=2x

subtract 20 from both sides

80=2x

divide by 2

40=x

And Frank has $40

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.
