How o I get the awnser to 9s+3=57 I need help asap im in 8th grade

PIT_PIT [208]

First subtract 3 from both sides of the equal sign.
9s + 3 = 57
- 3 -3
9s = 54

Then divide both sides by 9.
9s = 54
/9 /9
s = 6

You can check it by plugging it back into the equation.
9s + 3 = 57
9 * 6 + 3= 57
54 + 3 = 37
57 = 57
Yep! It's correct! :)

Hope that helped. Algebra can be tricky sometimes I know but it's really just balancing equations.

$H_{0}$ : p=10%

$H_{a}$ : p>10%

The alternative hypothesis states that the parameter is greater than the hypothesized value.
