To find the reciprocal of a fraction, you just need to "flip" it. To check your work, you multiply the fraction and the reciprocal to get 1.

the reciprocal if 2/3 is 3/2

$\frac{2}{3} * \frac{3}{2} = \frac{6}{6} = 1$

The answer is B

Anne picked out 3 board games from her cabinet to take to a game night with her friends. She still has more than 10 board games

Tresset [83]

Answer:

x - 3 > 10

There were more than

board games in Anne's cabinet to start.

Step-by-step explanation:

The variable x represents how many board games were in Anne's cabinet to start. Since she has already picked out 3 board games to bring, the expression x–3 represents how many board games are still in the cabinet.

And, since Anne has more than 10 board games still in her cabinet, x–3 must be greater than 10.

This inequality shows the relationship.

x–3>10

Now, solve for x.

x–3

> 10

x–3+3

> 10+3 Add 3 to both sides

> 13 Simplify

So, there were more than 13 board games in Anne's cabinet to start.

-2/3 x -9/8 x -4/5 x -1

Lerok [7]

Answer: 0.6

Step-by-step explanation: First, you want so seperate the equations in parenthesis to make solving the equation easier.

(-2/3x-9/8x )-(4/5x)-(1)

So (-2/3x-9/8x) equals -11/24x

And -11/24x-4/5x equals -151/120x

So -151/120x-1 ends up being 0.6.

N^2 + 36n + c "find the value of c that completes the square"

RSB [31]

For this case we have the following polynomial:

$n ^ 2 + 36n + c$

To find the value of c that completes the square, we use the following equation:

$c = (\frac {b} {2}) ^ 2$

Where,

<em>b: coefficient of the variable of degree 1 </em>

Substituting values we have:

$c = (\frac {36} {2}) ^ 2\\c = (18) ^ 2\\c = 324$

Answer:

the value of c that completes the square is:

$c = 324$
