What is 4 hours and 39 mins before 7:53 p.m

Answers

Answer 1

Answer:

4 hours and 39 minutes before 7:53 p.m. is 6:34 p.m.

To find the time 4 hours and 39 minutes before 7:53 p.m., we can subtract the given time from the duration.

Step 1: Convert 4 hours and 39 minutes into minutes.

4 hours = 4 * 60 = 240 minutes

Total duration = 240 minutes + 39 minutes = 279 minutes

Step 2: Subtract the duration from the original time.

7:53 p.m. - 279 minutes

Subtract the minutes first:

53 minutes - 279 minutes = -226 minutes

Now, since the result is negative, we need to "borrow" an hour from the original time:

7 p.m. - 1 hour = 6 p.m.

So, 4 hours and 39 minutes before 7:53 p.m. is 6:34 p.m.

Y=4x+19
-8x-5y=-11
Can u help me on this

Answers

y=4x+19 (1)
-8x-5y=-11 (2)
sub 1 into 2
-8x-5(4x+19)=-11
-8x-20x-95=-11
-28x-95=-11
-28x=84
x=84/-28
x= -3
sub into 1
y=4(-3)+19
y=7

therefore x= -3 and y=7

I'm just going to do substitution
Steps:
1. Substitute the y in -8x-5y=-11 for 4x + 19

-8x-5(4x + 19)= -11
-8x + (-20x) + (-95)= -11
-28x + (-95)=-11
2. Now add 95 on both sides
-28x= 84
3. Divide by 28 on both sides
4. X=-3
5. Now substitute the x in y= 4x + 19 for -3
Y= 4(-3) + 19
Y= -12 + 19
Y= 7
6. Your answer is x = 3 and y= 7 or (3,7)
