No. The answer would be 6 because even though PEMDAS is a thing you have to multiply 3 with 4 and -2. That is how you do 3x4 is 12x then 3x-2 would be -6. So 12x-6 x=6

In order to solve for this equation, we need to isolate 'x', or figure out a way to keep 'x' on one side.

First, divide both sides by 3. This will get rid of the '3' in '3(4x - 2)':

4x - 2 = 4

Add 2 to both sides:

4x = 6

Divide both sides by 4:

x = 6/4

Simplify:
x = 3/2

Which set of points is not coplanar?

spin [16.1K]

we know that

Coplanar points are three or more points which lie in the same plane. Remember that a plane is a flat surface which extends without end in all directions. Any three points in 3-dimensional space determine a plane.

case a) points A, B, E

Any group of three points determines a plane

The points A,B,E are coplanar

case b) points A, B,C,E

The four points do not belong to the same plane

The points A,B,C,E are not coplanar

case c) points B, C, D

Any group of three points determines a plane

The points B, C, D are coplanar

case d) points A,B, C, D

The base of the pyramid is a flat surface, the four points lie in the same plane

The points A,B, C, D are coplanar

therefore

the answer is the option

points A, B, C, E are not coplanar

At a chocolate store, 70% of the items are dark chocolate and 30% are milk chocolate. Also 20% of the items have nuts and 80% ar

Delvig [45]

Answer:

A. 13%

Step-by-step explanation:

let's suppose there's 1000 bars of chocolate in general

70 % dark = 700 dark choco bars

30 % milk = 300 milk choco bars

20 % have nuts = 200 bars have nuts

80 % don't have nuts = 800 bars don't have nuts

if 90 % of dark chocolate bars don't have nuts, that means 630 dark chocolate bars don't have nuts, but 70 have nuts

200 bars in general have nuts, if only 70 dark chocolate bars have nuts,

200 - 70 = 130

130 = 13%
