3(4x+2) - 6x = 5x - 5(2 + x)
3·4x+3·2-6x=5x-5·2-5·x
12x+6-6x=5x-10-5x
12x-6x-5x+5x= -10-6
6x=-16
x=- \frac{16}{6}  \\ x=- \frac{8}{3}  \\ x=-2 \frac{2}{3}

3(4x + 2) - 6x = 5x - 5(2 + x)

First, expand the equation. / Your problem should look like: 12x + 6 - 6x = 5x - 10 - 5x
Second, simplify 12x + 6 - 6x to 6x + 6. / Your problem should look like: 6x + 6 = 5x - 10 - 5x
Third, simplify 5x - 10 - 5x to -10. / Your problem should look like: 6x + 6 = -10
Fourth, subtract 6 from both sides. / Your problem should look like: 6x = -10 - 6
Fifth, simplify -10 - 6 to -16. / Your problem should look like: 6x = -16
Sixth, divide both sides by 6. / Your problem should look like: x = -\frac{16}{6}
Seventh, simplify \frac{16}{6} to \frac{8}{3} / Your problem should look like: x = - \frac{8}{3}

Answer: x = - \frac{8}{3}

Select the expression that is equivalent to (x-3)^2
krek1111 [17]

Answer:

x² - 6x + 9

Step-by-step explanation:

(a - b)² =a² - 2ab + b²

a = x and b = 3

(x - 3)² = x² - 2*x*3 + 3²

           = x² - 6x + 9

katen-ka-za [31]

Answer:

1/3n-3<6

Step-by-step explanation:

One third of a number: 1/3

3 is subtracted from 1/3 of a number n: 1/3n -3

Result is less than 6: less is represented with the symbol <. So, the result of the expression 1/3n-3 is less (<) than 6.

The final expression:

1/3n-3<6

Assume that blood pressure readings are normally distributed with a mean of 124 and a standard deviation of 6.4. If 64 people ar
Murrr4er [49]

Answer:

99.38%

Step-by-step explanation:

We have that the mean (m) is equal to 124, the standard deviation (sd) 6.4 and the sample size (n) = 64

They ask us for P (x <126)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / (sd / (n ^ 1/2))

We have all these values, replacing we have:

z = (126 - 124) / (6.4 / (64 ^ 1/2))

z = 2.5

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <2.5) = 0.9938

The probability is 99.38%
