Answer:

(3, 2)

Step-by-step explanation:

What you do is you take the first problem and move the -2x to the other side with the y to get y+2x=8.

The next thing you do is you substitute the second problem into the y of the first problem like this: (x-1)+2x=8.

The next thing that you do is you add the x's together to get 3x-1=8.

After that, you will add the 1 to both sides to get 3x=9.

The last thing you will do is divide 3 on both sides to get x=3.

How you will solve the y is you take the 3 that you just found out is your x and pug it into the second equation to get y=3-1.

y=2.

(3, 2) is your answer.

Natalie's coach has a stopwatch that records times to the nearest thousandth of a second. Natalie ran a given distance in 25.453

sdas [7]

Answer:

25.5 seconds

Step-by-step explanation:

Given that the stopwatch records times to the nearest thousandth of a second, it means that the time recorded will be given at 3 decimal places.

To get the time in the nearest tenth of a second, we would first convert to the nearest hundredth of a second, at this, the reading of 25.453 seconds will be

= 25.45 seconds

Since the number at the hundredth position is 5 (or more), we would add 1 to the number at the tenth position to round it to the nearest tenth. Hence the reading to the nearest tenth

= 25.5 seconds
