The work of a student trying to solve the equation 2(2x − 3) = 6 + 2x + 4 is shown below: step 1: 2(2x − 3) = 6 + 2x + 4 step 2: 4x − 3 = 10 + 2x step 3: 4x − 2x = 10 + 3 step 4: 2x = 13 step 5: x = 6.5 in which step did the student first make an error and what is the correct step?

step 2: 4x − 6 = 10 + 2x
step 2: 4x − 3 = 2 + 2x
step 3: 4x + 2x = 10 + 3
step 3: 4x − 2x = 10 - 3

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?

Can anyone explain to me how to do this? anything will .
