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.

Evaluate the following expression. (-3)-2

harkovskaia [24]

Integers are whole numbers that are either positive or negative. Operation of signs is important when dealing with integers.
In this case, -3 and -2 are integers that are being added.
if we add -3 by -2 we get -6 because when a negative number is added to a negative number the negative sign does not change
thus, (-3)-2 = -5
