Simplify: <br><br> 6x + 2 - 1 - 4 - 3 - 2x + 2

IrinaK [193]

Answer:

4x - 4

Step-by-step explanation:

Combine like terms. Like terms are terms with the same variable as well as the same amount of variables:

6x - 2x + 2 - 1 - 4 - 3 + 2

(6x - 2x) = 4x

(2 - 1 - 4 - 3 + 2) = (2 + 2) + (-1 - 4 - 3) = (4) + (-8) = -4

4x - 4 is your answer.

Am I correct on number 3? If not whats the correct answer? And what is the answer for number 4? Will be marking brainliest!!

Answer for number 4 is $\frac{\bold2}{\bold3}$ hour.

Step-by-step explanation:

Maximum hour spent for all homework (English homework + math homework) is 2 hours.

Let us assume the hours spent for English homework be 'e'.

It is given that:

(Hours spent for math homework) = 2 × (Hours spent for English homework)

Hours spent for math homework = 2 × e = 2e

Total hours spent = (Hours spent for math homework) + (Hours spent for English homework)

Total hours spent = 2e + e = 3e

2 = 3e

3e = 2

∴ e = $\frac{\bold2}{\bold3}$

Therefore number of hours spent on English homework is equal to $\frac{\bold2}{\bold3}$ hours.
