1. how can we get equation B from A

A. 4x+2=6-x

B. 5x+2=6

since equation a has -x on one side just add x to both sides to get rid of the -x and since you do it to both sides you maintain balance

Step-by-step explanation:

4x+x=6-2

5x=6-2

5x+2=6

Step-by-step explanation:

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
