Answer:

Step-by-step explanation:

When looking at the number line, we can see the distance between A and B is one unit

A |-2| + |-1| = 2+1 =3 That is not 1 unit

B 2-1 =1 that is 1 unit

C -2 + -1 = -3 that is not 1 unit

D |-1| - (-2) = 1 + 2 =3 that is not 1 unit

Even though it says all expressions, there is only 1 that shows a distance of 1 unit

Which of the following are the subset of ,B={1,2,3,4,5,6,7,8,9,10}.

Verdich [7]

Answer:

A, C, T

Step-by-step explanation:

A subset simply means a set of which all of its elements are contained in a larger set :

To obtain the subsets of B={1,2,3,4,5,6,7,8,9,10}.

We observe the smaller sets whose entire elements can be found in B

D={0,2,4,6,8,10,12} = not a subset of B ; B does not contain 0

A={5,6,7} = subset of B, all elements Cann be found in B

C={2} = subsets of B, 2 can be found in B

T={1,2,3,4,5,...,8} = subset of B; all elements can be found in B

Find 3 1/6 + (-4 1/3).

jeka94

Answer:

-1 1/6

Step-by-step explanation:

$3\frac{1}{6} + (-4\frac{1}{3} )$

Convert the mixed numbers into improper fractions

$\frac{19}{6} + (-\frac{13}{3} )$

Apply the rule: a + (-b) = a - b

$\frac{19}{6} + (-\frac{13}{3} ) = \frac{19}{6} - \frac{13}{3}$

The Least Common Multiplier of 6 and 3 is 6

Adjust the fractions on the LCM

$\frac{19}{6} - \frac{26}{3}$

Apply the Fraction Rule: $\frac{a}{c} -\frac{b}{c} = \frac{a - b}{c}$

$\frac{19 - 26}{6}$

Subtract the numbers

$\frac{-7}{6}$

Apply the Fraction Rule: $\frac{-a}{b} = - \frac{a}{b}$

$-\frac{7}{6}$

Convert improper fraction into a mixed number

$-1\frac{1}{6}$

Hope this Helps :)
