Answer:
x = 30/7
Step-by-step explanation:
2/3x = − 1/2x + 5
multiply by 6 to clear the fractions
4x = -3x + 30
add 3x to both sides
7x = 30
Divide both sides by 7
x = 30/7

Answer:
Here is your answer hope this helps!
Step-by-step explanation:
Question 1 4(3x+2)-2
Step 1 use distributive property which is (4times3x)+(4times2)-2
Step 2 solve =12x+8+-2
step 3 use combine like terms so its (12x)+(8+-2)
The answer is 12x+6
Question 2 is 4(5b-4)
Answer:
The standard error of the sample mean is 0.57
Step-by-step explanation:
we know that
The Standard Error Formula is given by the formula
where:
SE = standard error
s = standard deviation
n = the sample size
In this problem we have
substitute in the formula
