Answer:

Rational

Step-by-step explanation:

A rational number is any integer, fraction, terminating decimal, or repeating decimal.

3 repeats itself, so it's rational.

Answer: Rational

This is because the number is in the form P/Q where P and Q are integers

We have P = -13 and Q = 12.

You can think of "rational" as in "ratio" which is very closely tied to fractions. Any rational number is a fraction of two integers. The denominator can never be zero.

The solution to -3(2 - 5x) = 3x + 12 is<br> 1. -2.25<br> 2. -1.625<br> 3. 1.5<br> 4. 3
Nonamiya [84]

Answer:

1.5

Step-by-step explanation:

i am not certain but this is how I got it

First distribute which gives you the -3 with 2 I switched them around so I did -3(-5x+2) and you will get 15x-6

Then the opposite of subtraction is addition so you add 6 to both sides so you add six to 12 and to 6 leaving you with 15x=3x+18 you then will subtract 3x from 15x and 3 leaving you with 12x=18 the divide the numbers

After you divide you get 3/2 then put it has a decimal and you get 1.5

Mr. Rivera can grade 18 math teat in 15minutes. What is the teachers unit rate?
Andru [333]

In this question, you're trying to find the unit rate in which the teacher can grade tests.

A unit rate is another word for "rate of change".

This means that we have to find how many tests the teacher could grade in 1 minute.

To find the unit rate, divide 18 by 15

18 ÷ 15 = 1.2

This means that Mr. Rivera can grade 1.2 tests in 1 minute.

Answer:

1.2 tests
