How would you solve a equation with X and Y on the same side?

I think this is the answer. Not sure though.

Step-by-step explanation:

Take 3x, for example

3x will equal to (4x - 10)

So, in other words, the equation is

(4x - 10) + 3x = 10

= 7x - 10 = 10

7x = 10 + 10

= 20

x = 20/7

x =  2.85

y = 4x - 10

= (4 x 2.85) - 10

= 11.4 - 10

= 1.4.

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;
