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

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

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

A cube with sides 5 inches, and a pyramid with base edges 5 inches. What is the height, so that the volume of the cube and the p

Ostrovityanka [42]

<u>1</u><u>5</u><u> </u><u>inches</u> is the height of the pyramid

Step-by-step explanation:

The volume of a cube is a³

Given <em>a</em> = 5 inches

→ Volume = a³

= 5³

= 5×5×5

= <u>125 in²</u>

The volume of a pyramid is $\frac{1}{3} {a}^{2}h$

Given a = 5 inches , h = height of pyramid

$= > \frac{1}{3} {a}^{2} h$

$= > \frac{1}{3}(5)^{2}h$

$= > \frac{1}{3} \times 25 \times h$

$= > \frac{25}{3}h$

then,

$125 = \frac{25h}{3}$

$= > 25h = 125 \times 3$

$= > 25h = 375$

$= > h = \frac{375}{25}$

$= > h = 15$

Hence, the height of pyramid is <u>1</u><u>5</u><u> </u><u>inches</u>
