Answer:

x = -12

Step-by-step explanation:

2x^2 + 8 = x^2 - 16

2x + 2x + 8 = x + x - 16

4x + 8 = 2x - 16

-2x        -2x

2x + 8 = -16

      -8     -8

2x = -24

----   ------

2        2

x = -12

He school that Tony goes to is selling tickets to a play. On the first day of ticket sales the school
UNO [17]

Answer:

The price of 1 adult ticket is 12 dollars, and the price of a ticket for one student is 7 dollars

Step-by-step explanation:

Make a system of equations for the two days that the play was shown.

Let x = the price of an adult ticket

Let y = the price of a student ticket

For the first day:

<h3>9x+8y=164</h3>

For the second day:

<h3>2x+7y=73</h3>

Now, we can solve using the elimination method. Multiply the first equation by 2 and the second equation by 9. Then swap the order of the equations.

<h3>18x+63y= 657</h3><h3>-</h3><h3>18x+16y= 328</h3><h3>0x+ 47y= 329</h3><h3>divide both sides by 47</h3><h3>y = 7</h3><h3>Plug in 7 for y for the 2nd equation</h3><h3>2x+7(7)=73</h3><h3>2x+49=73</h3><h3>subtract 49 from both sides</h3><h3>2x= 24</h3><h3>divide both sides by 2</h3><h3>x = 12 </h3><h3>Check:</h3><h3>2(12)+7(7)=73</h3><h3>24+49= 73!</h3>

Write 2/15 as a decimal.
Cloud [144]
If you need to write a number as a decimal, it means that you need to write is a an x divided by a power of 10.
you can use this formula:
\frac{2}{15} = \frac{x}{10}

now let's multiply both sides by 10:
\frac{20}{15} = x
and simplyfy:
(by dividing the first fraction's elements by 5)
\frac{4}{3} = x

change improper fraction into a mixed number
1\frac{1}{3} = x

and 1 over 3 is 0.33333...

so the  answer is 1.333333 - we can also write it as 1.(3)

Please explain step by step​
JulijaS [17]
1. Calculate the volume of entire cube as if it was a solid rectangle:
Length x width x height=
20x16x12 = 3,940 cubic inches

2. Calculate the volume of the "missing"
Piece and subtract:
Length x width x height=
20x8x6 = 960 cubic inches
(notice you can find the height of the missing piece by subtracting 12-6)

So your answer is 3,940-960 = 2,980 cubic inches inside the steps
