1) add.

for example -1 + -2 = - (||-1| + |-2||), which is -(1+2) or -3


2) subtract

for example 4 + -7 = -(||-7| + |4||), which is - |7 - 4| or -3


3) change
for example 3 - (- 2) = 3 + 2


4) -10

the sum is -10.25, which is closest to -10

If time is four hours from now, the time left till midnight would be quarter that if it is one hour from now. What time is it no
lapo4ka [179]

Answer:

The time now is 7 pm

Step-by-step explanation:

Suppose that now is the time T.

We know that:

"if time is four hours from now, the time left till midnight would be a quarter that if it is one hour from now".

Then:

if we define midnight as 12, and we assume that T is in the pm range.

Then the "time left till midnigth, assuming that the time is four hours from now" will be written as (12 - (T + 4))

With this in mind, we can write the problem as:

12 - (T + 4) = (1/4)*( 12 - (T + 1))

Now we can solve this for T.

12 - T - 4 = (1/4)*(12 - T - 1)

8 - T = (1/4)*(11 - T)

4*(8 - T) = 11 - T

32 - 4*T = 11 - T

32 - 11  = -T + 4*T

21 = 3*T

21/3 = T

7 = T

Then T = 7 pm

The time now is 7 pm
