-6(2+a)=-48 what is the value for a<br>​
GrogVix [38]

Answer:

\boxed{A=6}\checkmark

The answer should have positive sign.

Step-by-step explanation:

First you do is divide by -6 from both sides of an equation.

\frac{-6(2+a)}{-6}=\frac{-48}{-6}

Then, simplify and solve the problem.

-48/-6=8

2+a=8

Next, you switch sides.

a+2=8

You subtract by 2 from both sides of an equation./

a+2-2=8-2

Finally, solve/simplify.

8-2=6

A=6 is the correct answer.

Hope this helps you!

Have a nice day! :)

GREYUIT [131]

The total cost for utilities last month is 353,571.43.

<h3>What is the total cost for utilities last month?</h3>

The total cost for utilities last month can be determined by multiplying the volume of the stadium by the cost per cubic foot.

The volume of the stadium can be determined by using the formula for the volume of a hemisphere.

Volume of a hemisphere = Volume of a hemisphere = (2/3) x (n) x (r^3)

n = 22/7

r = radius

2/3 x 22/7 x 150³ = 7071,428.57

The total cost for utilities last month =  7071,428.57 x 0.05 = 353,571.43
