Answer:

Step-by-step explanation:

Divide 712 hours by 24 hours/day, obtaining 29 2/3 days, which in turn breaks down into 28 days plus 1 2/3 days, or 4 weeks plus 1 2/3 days.  '4 weeks' takes us to a Monday, 22:48, 4 weeks after the start of the journey.

To this we add 1 2/3 days, reaching 16 hours into the Tuesday immediately following that Monday.  That would be approximately 16:00 on that Tuesday, but we must work backwards 1:12 hours:  subtracting 1:12 from 16:00 on Tuesday yields 14:48

The journey finishes at 14:48 4 weeks and 1 day after it began.

Use substitution to solve the system. <br><br><br> X= 2y-5<br> 4x+3y=-9
sergey [27]

Step-by-step explanation:

x=2y-5 - equation 1

4x+3y=-9 -equation 2

Replace equation 1 in equation 2

4(2y-5)+3y=-9

8y-20+3y=-9

11y=-9+20

11y=11

y=11/11

y=1

If y=1, therefore x=2(1)-5=-3

x=-3,y=1

Many years ago, the towns of Franklin and Chester agreed to begin posting their populations on signs just
Sergeu [11.5K]

Answer:

Franklin's population < Chester's population by 4500

Step-by-step explanation:

Franklin: 20000 (1 + 0.05) = 21000   (21000 - 20000 = 1000 grew)

Chester: 25000 + 500 = 25500        (500 increase)

4.) 2(x-1)+3= 2x+1

Distribute the 2, multiply the 2 by x and -1.

2*x= 2x (all you need to do is put 2 in front of x)

2*-1= -2

2x-2+3= 2x+1

Combine like terms. 

2x+1=2x+1

Subtract one on both sides. 

2x=2x

Divide by 2 into both sides. 

x=1

We can check this by plugging it in. 

2(1-1)+3= 2(1)+1
2(0)+3= 2+1
0+3=3
3=3 <== this works

I hope this helps!
