Answer:

x=2.5

Step-by-step explanation:

• Distributive Property

-6x+8+9=2x+3

• Add like terms

-6x+17=2x+3

• Move like variables over equal sign

17=2x+3

+6x (the sign flips once across equal sign)

• Same thing with the whole #s

17=8x

+3

• Get "x" by itself by dividing the 8 on both sides

(÷8) 20=8x (÷8)

• Equals

x=2.5

In a class of all girls, 22 of the 28 students have brown hair. What is the
Verdich [7]

Answer:

\frac{3}{14}

Step-by-step explanation:

Total Students = 28

Brown Hair = 22

NOT Brown Hair = 28 - 22 = 6

The probability of an event is the number of that event divided by total number.

So, let denote probability of without brown hair be  P(NOT BROWN). So, we can say:

P(NOT BROWN) = 6/28

Reducing, we get:

P(NOT BROWN) = 3/14

Sammy has 2 pairs of jeans, 3 pairs of black pants, and 1 skirt. She also has 2 pink shirts, 4 striped shirts, and 2 hooded swea
Semenov [28]

I'm not too sure if this a a question for school but i think it really depends on what Sammy wanna wear. I would also say she may wear black pants and a striped shirt because of the amount she has of them. All the other clothes have only two pairs, So because she has more than two pairs for black pants and striped, it means that she likes that outfit of the black pants and striped shirt so she will most likely wear them.
