Answer:

x = 3

Step-by-step explanation:

x + 6 = 2x + 3 \\ subtract \: 2x \: from \: both \: sides \\  \\  -1x + 6 = 3 \\ subtract \: 6 \: from \: both \: sides \\  \\  - 1x =  - 3 \\  divide \: both \: sides \: by \:  - 1 \\  \\ x = 3

Answer:

3

Step-by-step explanation:

x + 6= 2x + 3

what you would do to find the answer is first subtract the coeffcient 2 on both sides of the equation. ( Subtract the 2 under 2x for the right side of the equation and subtract 2 under the x on the left side. ) Then you would subtract 6 on both sides. (subtract 6 under the 6 on the left side of the equation and subtract 6 under the number 3 on the right side of the equation)

so that would give you -x = -3 However you would have to eliminate the x on the right side of the equation and so you would divide positive x (also known as 1x) on both sides. -1x/-1 = -1  and -3/-1 = 3

A normal distribution has a mean of 15 and a standard deviation of 4. What percent of values are from 15 to 23
muminat

Answer:

47.72%

Step-by-step explanation:

Given

Mean (u) = 15

SD = 4

P(15<x<23) = P(\frac{x-u}{\sigma}

= P(\frac{15-15}{4}

=P(0<z< 2)

=P(z<2) - P(z<0)

Use standard normal table to find probability of the z score

= 0.9772 - 0.5

= 0.4772 \approx\\ 47.72%
