the conjunction, x<3 and x>-1, may be written -1

Answers

Answer 1
Answer:   -1 < x < 3

===========================================================

Explanation:

The first thing to do is to swap the positions of the x < 3 and the x > -1

So you'll end up with x > -1 and x < 3

Now focus entirely on x > -1. Swap the left and right sides, and also swap the inequality sign. So we end up with -1 < x

That means the "x > -1 and x < 3" is the same as "-1 < x and x < 3"

From here, we collapse the two inequalities to form the compound inequality -1 < x < 3

We can say "x is between -1 and 3, excluding either endpoint".

I believe, by process of elimination, it is "Kara's fee for the second child is $5"

Step-by-step explanation:

It can't be the second option because if her hourly rate for 2 kids was 14, then on hour 2 the total would be $28.

It can't be the third option because Jill's pattern is $11 dollars an hour, and Kara's is adding $9. So, by hour 4, Jill would make $44 and Kara would make $41.

Lastly, it can't be the 4th option because 11-9=2. 2 does not equal 3.

Place the following in order from least to greatest. 8,000,000 mm, 5 km, 7000,000 cm, 6,000 m

Answers

Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm

Step-by-step explanation:

Note that:

1km = 1,000,000mm

1m = 1000mm

1cm = 10mm

Therefore,

5 km = 5 × 1,000,000mm = 5,000,000mm

7000,000 cm = 7,000,000 × 10 = 70,000,000mm

6,000 m = 6000 × 1000 = 6,000,000mm

Therefore, from the least to the greatest will be:

5km, 6000m, 8,000,000 mm, 7000000 cm
