Rearrange y =1/2x+1to make x the subject.
ella [17]

❤❤❤❤❤❤❤❤❤❤❤❤❤❤

y =  \frac{1}{2} x + 1 \\

Multiply sides by 2

2 \times y = 2 \times ( \frac{1}{2} x + 1) \\

2y =( 2 \times  \frac{1}{2} x) + (2 \times 1) \\

2y = x + 2

x + 2 = 2y

Subtract sides 2

x + 2 - 2 = 2y - 2

x = 2y - 2

Done...

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!
