You spend 30 minutes reading emails. You then spend 2 hours playing video games . Write the ratio of the amount of time reading emails to the amount of time spent playing on video games as a fraction in a simple form.

Step-by-step explanation:

Step 1: State what is given

2 hours playing games or 120 minutes

30 minutes reading email

Step 2: Put information into fraction

Step 3: Simplify the fraction by 30

Therefore the fraction representing how long he plays games and reads email is

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.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
