If n is the average of three numbers x, 12, and 15, what is the value of x?

Answers

Answer 1

Answer: 9- because it looks like 12 and 15 were multiplied by 3,
3x5= 15
3x4= 12
3x3= 9

Explain why the equation 2(3x - 5) = 6x + 8 has no solutions.

Answers

Answer:

Look at step-by-step solution

Step-by-step explanation:

2(3x-5)=6x+8

First start by dividing two from the left side:

3x-5=3x+4

From there add five and subtracted 3x from both sides:

0=9

Since zero does not equal nine, there is no solution.

Answer:

- 5 does not equal 8

Step-by-step explanation:

Distribute the 2 to get 6x - 5 = 6x +8

6x - 5 = 6x + 8

subtract 6x on both sides you are left with -5 = 8 which is not a true statment.

Since the equation leads to a statment that isn't true, there is no solution.

Find the equation of a line perpendicular to y - 12 = 2x – 8 that passes through the point (2, 3). (answer in slope-intercept form)

Answers

Hello,

The slope of y-12=2x-8 is 2 thus the perpendicular will have as slope -1/2

y-3=-1/2(x-2)
or y=-x/2 + 4 is the equation searched.

Answers

3x -y = 4 ------> eqn1
2x + y = 11 ------> eqn2
add the two equations
3x -y +2x +y = 11 + 4
5x = 15
x = 3
then sub. in eqn 2
2(3) + y =11
y= 11 -6
y = 5
the answer is ( 3, 5)
