Answer: -5 and -7

Step-by-step explanation:

|\frac{x}{2}+3| = \frac{1}{2}

It has 2 cases

the first case ;

\frac{x}{2} + 3 = \frac{1}{2}

\frac{x}{2} = \frac{-5}{2}

x = -5

the second case;

\frac{x}{2} + 3 = \frac{-1}{2}

\frac{x}{2} = \frac{-7}{2}

x = -7

12 less than the quotient of a number and seven is -2 find the number
kiruha [24]
A quotient is the result of a division.
Let the unknown number be x.

We translate the problem into an equation, piece by piece.

<span>"quotient of a number and seven"  ---->   x/7
</span>
<span>"12 less than the quotient of a number and seven"  ---->    x/7 - 12

The word "is" means "="
x/7 - 12 =

All the above is -2, so it equals -2.

x/7 - 12 = -2

\dfrac{x}{7} - 12 = -2

First, add 12 to both sides and simplify.

</span><span>\dfrac{x}{7} - 12 + 12 = -2 + 12

</span>
<span><span><span>\dfrac{x}{7} = 10</span>
</span>
Next, multiply both sides by 7.

\dfrac{x}{7} \times 7 = 10 \times 7

x = 70
</span>
Answer: The number is 70.

Which of the following expressions shows how to rewrite 5 − 6 using the additive inverse and displays the expression correctly o
Andru [333]

The correct display of the expression on a number line is number line (c)

<h3>How to determine the expression that shows how to rewrite 5 − 6 using the additive inverse?</h3>

The complete question is added as an attachment

The expression is given as:

5 - 6

Put 6 in a bracket.

So, we have:

5 - 6 = 5 - (6)

Express 6 as --6

So, we have:

5 - 6 = 5 - -(-6)

Rewrite as:

5 - 6 = 5 + (-6)

The above means that the arrow on the number line must start from 5 and moves in the negative direction in 6 units

The correct display of the expression on a number line is number line (c)
