Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10
Answer:
D) 3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Divisions
Additions
Subtractions
~
First, subtract 4 from both sides of the equation:
2x + 4 (-4) = 10 (-4)
2x = 10 - 4
2x = 6
Next, divide 2 from both sides of the equation:
(2x)/2 = (6)/2
x = 6/2
x = 3
D) 3 is your answer.

Answer:
<em>∠6 = 78°.</em>
Step-by-step explanation:
<em>∠3 = 78°</em>
<em>∠2 and ∠3 are vertical angles, => ∠2 = ∠3 = 78°.</em>
<em>∠2 and ∠6 are corresponding angles, => ∠6 = 78°.</em>
