If R is the set of all integers, choose the set S that will make the following statement false.S ⊆ R
1 S = {−2, −1, 0, 1, 2}
2 S = {0, 0.5, 1, 1.5}
3 S = {0}
4 S = {1, 2, 3, 4}

Answers

Answer: 1 S = {−2, −1, 0, 1, 2}

Step-by-step explanation:

Integers are whole numbers that could be positive or negative .

This means that

R = { ... -3 ,-2 , -1 , 0 , 1 , 2 , 3 , 4 , ...}

S ⊆ R means that all elements of S is also an element in R , therefore :

The current temperature in Smallville is 20 degrees. This is 6 degrees less than twice the temperature that it was six hours ago. What was the temperature six hours ago?

Answers

ANSWER:  

The temperature in Small ville, six hours ago was 13 degrees.

SOLUTION:

Given, current temperature in Smallville is 20 degrees.  

And this is 6 degrees less than twice the temperature that it was six hours ago.

We need to find what was the temperature six hours ago.

Let the temperature six hours ago be x.

Then, 2x - 6 = 20 [ according to the given information

2x = 20 + 6

2x = 26

x = (26)/(2)

x = 13 degrees.

Temperature six hours ago was 13 degrees

Hence, the temperature in smallville , six hours ago was 13 degrees.
