Multiply the additive inverse of (-7/8) by the reciprocal of (5 1/2)<br><br>PLEASE HELP!

EleoNora [17]

Answer:

$\bold {$\dfrac{7}{44}$}$

Step-by-step explanation:

<h3> Reciprocal:</h3>

$\sf \text{The reciprocal of any number $\dfrac{a}{b}$ is given by $\dfrac{b}{a}$}\\\\5\dfrac{1}{2}=\dfrac{11}{2}\\\\\text{Reciprocal of $\dfrac{11}{2}$ = $\dfrac{2}{11}$}$

<h3>Additive inverse:</h3>

$\text{Additive inverse of $\dfrac{-7}{8}$=$\dfrac{7}{8}$}$

Now multiply,

$\sf \dfrac{7}{8}*\dfrac{2}{11}=\dfrac{7}{4}*\dfrac{1}{11}\\$

$=\dfrac{7}{44}$

Solve this equation showing work − 9 ≥− 8(1 + 6v) − 1

Flauer [41]

Answer:

v≥0

Step-by-step explanation:

−9≥−8(1+6v)−1

Step 1: Simplify both sides of the inequality.

−9≥−48v−9

Step 2: Flip the equation.

−48v−9≤−9

Step 3: Add 9 to both sides.

−48v−9+9≤−9+9

−48v≤0

Step 4: Divide both sides by -48.

−48v

−48

≤
