Answer:

The driver took shorter than estimated

It took shorter by 2 hours( 120

minutes)

Step-by-step explanation:

Firstly we want to know if the drive took longer or shorter

By 2 days, the number of hours will be 2 * 24 = 48 hours ( recall 24 hours = 1 day

now , since 60 minutes give one hour, then 48 hours will me 60 * 48 = 2,880 hours

This is less than 3,000 hours

By how much?

Simply subtract the value of minutes in 48 hours from 3,000 = 3000-2880 = 120 minutes ( or two hours)

Solve the system using elimination.5x-9y=12x-9y=-12
NemiM [27]

Answer:

x = 6

y = 2

Explanation:

To solve the system using elimination, we need to multiply the second equation by -1, so the second equation is equivalent to:

x - 9y = -12

-1 (x - 9y) = -1 (-12)

-x + 9y = 12

Then, we can sum this equation and the first equation. So:

5x - 9y = 12

-x + 9y = 12

4x + 0 = 24

So, we can solve for x, as:

4x = 24

4x/4 = 24/4

x = 6

Then, we can replace x by 6 on the first equation and solve for y, so:

5x - 9y = 12

5(6) - 9y = 12

30 - 9y = 12

30 - 9y - 30 = 12 - 30

-9y = -18

-9y/(-9) = -18/(-9)

y = 2

Therefore, the solution of the system is x = 6 and y = 2
