Lemur [1.5K]3 years ago

Answer:

First answer:

"<em>The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational."</em>

Step-by-step explanation:

Both 1.12 and 18/7 are rational numbers (meaning that they can be written as a quotient of integer numbers:

1.12 = 112/100

Then, since the addition of rational numbers is also a rational number, their sum is another rational number.

Then the correct answer is:

<em>The sum is rational because both 1.12 and 18 are rational, and the sum of rational numbers is rational.</em>

- 9(x + 2) &gt; 9(x – 3)
mezya [45]

Answer:

x < 1/2

Step-by-step explanation:

Distribute: -9x - 18 > 9x - 27

Collect like terms: -18x > -9

Divide both sides by -18: x < 1/2.

The sign changes because both sides were divided by a negative number.

Can you help with this. Thanks!

92 males buy tickets so
200-92=108
so 108 females buy tickets

30 males buy business and a total of 44 people (female and male) but business so 44-30=14
14 females buy business

108-14(business ticket) = 94 females left.
62 of those 94 females buy economy tickets
so therefore 94-62=32. 32 females left over

14 females = business
62 females = economy
14 + 62 = 76
108 - 76 = 32
32 remaining females buy premium


it says a total of 60 people buy premium so 60 - 32 = 28

so 28 males buy premium

hope this helped

The given number is 3.75, we will read the number separately first as follows:
before the decimal point we have 1 3 which is read as three
after the decimal point we have a .75 which is read as seventy-five hundredth

So, combing the two parts, we can find that the word form of 3.75 is:
three and seventy-five hundredth.
