Solve a two- step equation 6x+8=50

2 answers:

6 0

First subtract 8 from both sides so 6x+8-8=50-8
Which is 6x=42 then divide both sides by 6:
6x/6=42/6
x=7

4 0

X = 7 . You have to subtract the total from the amount your adding, then divide the 6. then you get your answer

Answer:

0.0445937

Step-by-step explanation:

-Given that the sample statistic has a mean of 406 grams, standard deviation of sq root(225) and the null statistic is 411 grams.

-Assuming normal distribution, the test statistic is calculated as:

$z=\frac{Sample \ statistic-Null \ statistic}{\sigma/\sqrt{n}}\\\\=\frac{406-411}{\sqrt{225/26}}\\\\=-1.6997$

-we then find the p-value of the test statistic from the z-tables:

P-value=0.0445937
