To solve for the value of x, it is easiest by isolating "x" to one side of the equation. This method is shown below:

-2x - 13 = 8x + 7

Adding 2x to both sides:

-2x - 13 + 2x = 8x + 7 + 2x
-13 = 10x +7

Subtracting 7 from both sides:

-13 - 7 = 10x + 7 - 7
10x = -20

Dividing both sides by 10:

10x / 10 = -20 / 10
x = -2

On a particular night, a baseball stadium sells 60% of its seats, and of those, 15% do not end up showing up to the game.Assumin
Lelechka [254]

Answer:

Step-by-step explanation:

so llets find what 15% of 60% really is,

0.15*0.60=0.09

0.09 AKA 9%

so since 9% of people didn't show up we can subtract 9% from 60%

so 60-9=51

51% of setas are taken

to find the percent of seats still empty, subtract 100 form 51

so

100-51=49

49% of seats are still empty

Hope this helsp!

fredd [130]
3/4 of a bushel is 75%, 2/3 of a bushel is 66.67% about. Being that both cost $9 the first store who is selling 3/4 of a bushel is a better deal because you get more for what you pay for.
