What is the answer to 19=-3a-5

stepan [7]

Answer:

$\fbox{ \huge{ \sf{ a = - 8}}}$

Step-by-step explanation:

$\bigstar{ \sf{ \: 19 = - 3a - 5}}$

$\tt{Step \: 1 \: }$ : Swap the sides of the equation

$\longmapsto{ \sf{ - 3a - 5 = 19}}$

$\tt{Step \: 2 \: }$ : Move 5 to right hand side and change it's sign

$\longmapsto{ \sf{ - 3a = 19 + 5}}$

$\tt{Step \: 3 \: }$ : Add the numbers : 19 and 5

$\longmapsto{ \sf{ - 3a = 24}}$

$\tt{Step \: 4 \: }$ : Divide both sides by -3

$\longmapsto{ \sf{ \frac{ - 3a}{ - 3} = \frac{24}{ - 3}}}$

$\tt{Step \: 4}$ : Calculate

$\longmapsto{ \sf{a = - 8}}$

$\sf ∴ \: the \: value \: of \: a \: is \: - 8.$

What is the distance between (22,-3) and (1, -3)?

Bingel [31]

Answer:

Option D

Step-by-step explanation:

<h2>Distance between two points</h2>

The y-value of the two points is unchanged. So, the line is parralel to x-axis.

The distance will be the diffrence between the x-co ordinates.

$\sf Distance = 1 - (-2\dfrac{1}{2})$

$\sf =1+\dfrac{5}{2}\\\\= \dfrac{2}{2}+\dfrac{5}{2}\\\\=\dfrac{7}{2}\\\\=3\dfrac{1}{2}$
