Question 1

Find -x for the given value of x.
-$$x = \frac { 1 } { 2 }$$

Accepted Answer

To find -x when $x = \frac{1}{2}$, you simply negate x, resulting in $-\frac{1}{2}$.

Question 2

-0 + (-11.3 )

Accepted Answer

Adding 0 to any number does not change the value of that number, so 0 + (-11.3) equals -11.3.

Question 3

-14.7 + (-14.7)

Accepted Answer

When you add a number to its negative, the result is always 0.

Question 4

Find the absolute value.
-$$- \left| - \frac { 13 } { 3 } \right|$$

Accepted Answer

The answer of Find the absolute value.
-\[- \left| - \frac...

Question 5

Find -x for the given value of x.
-$$x = - \frac { 5 } { 9 }$$

Accepted Answer

To find -x when $x = - \frac{5}{9}$, you change the sign of x, resulting in $-(-\frac{5}{9}) = \frac{5}{9}$.

Question 6

Find -x for the given value of x.
-$$x = - \sqrt { 10 }$$

Accepted Answer

The negative of $x = -\sqrt{10}$ is $x = \sqrt{10}$, because negating it removes the initial negative sign.

Question 7

Add as indicated.
--12 + 8

Accepted Answer

When adding a negative number to a positive number, you subtract the smaller number from the larger number and keep the sign of the larger number. So, -12 + 8 = -4.

Question 8

Subtract as indicated.
-1 - 12

Accepted Answer

Subtracting 12 from 1 gives -11.

Question 9

--14.9 + (-13.7)

Accepted Answer

When you add two negative numbers together, you get a negative result. Adding -14.9 and -13.7 gives -28.6.

Question 10

-$- \frac { 5 } { 9 } - \frac { 3 } { 4 }$

Accepted Answer

To subtract the fractions, find a common denominator, which is 36. Convert $-\frac{5}{9}$ to $-\frac{20}{36}$ and $-\frac{3}{4}$ to $-\frac{27}{36}$. Subtract: $-\frac{20}{36} - \frac{27}{36} = -\frac{47}{36}$.

Question 11

Find -x for the given value of x.
-$$x = - 26$$

Accepted Answer

To find -x when x = -26, you change the sign of x, resulting in -(-26) = 26.

Question 12

Find -x for the given value of x.
-$$x = - \frac { 11 } { 7 }$$

Accepted Answer

To find -x when $x = - \frac{11}{7}$, you change the sign of x. Thus, $-x = -(- \frac{11}{7}) = \frac{11}{7}$.

Question 13

Add as indicated.
--16 + (-17)

Accepted Answer

When adding two negative numbers, you add their absolute values and keep the negative sign. So, -16 + (-17) = -(16 + 17) = -33.

Question 14

-$\frac { 2 } { 3 } + \left( - \frac { 5 } { 9 } \right)$

Accepted Answer

To add fractions, they must have a common denominator. The least common denominator of 3 and 9 is 9. Convert $\frac{2}{3}$ to $\frac{6}{9}$ so it has the same denominator as $\frac{-5}{9}$. Then, $\frac{6}{9} + \left(-\frac{5}{9}\right) = \frac{1}{9}$.

Question 15

Find -x for the given value of x.
-$$x = \frac { 3 } { 8 }$$

Accepted Answer

To find -x when $x = \frac{3}{8}$, you simply multiply x by -1, resulting in $-\frac{3}{8}$.

Question 16

Add as indicated.
-11 + (-14)

Accepted Answer

When adding a positive number (11) and a negative number (-14), you subtract the smaller number from the larger number and keep the sign of the larger number, resulting in -3.

Question 17

Add as indicated.
--5.4 + 5.2

Accepted Answer

When adding -5.4 and 5.2, the negative number reduces the positive number, resulting in -0.2.

Question 18

Find -x for the given value of x.
-$$x = 21$$

Accepted Answer

To find -x when x = 21, you simply put a negative sign in front of 21, making it -21.

Question 19

Find -x for the given value of x.
-$$x = - 2.2$$

Accepted Answer

To find -x when x = -2.2, you change the sign of x, resulting in 2.2.

Question 20

Find -x for the given value of x.
-x = 23

Accepted Answer

The negative of x, when x = 23, is -x = -23.
