3(4x - 2) = 5x + 15

multiply the bracket by 3

(3)(4x)=12x

(3)(-2)=-6

12x-6=5x+15

move 5x to the other side

sign changes from +5x to -5x

12x-5x-6=5x-5x+15

12x-5x-6=15

7x-6=15

move -6 to the other side

7x-6+6=15+6

7x=15+6

7x=21

divide both sides by 7 to get x by itself

7x/7=21/7

Answer: x=3

Prudence has 12 pairs of gold earrings and 12 pairs of silver earrings.

Total Number of Earrings =12+12=24

Relative Frequency of Picking a Gold Earrings =12/24= 0.5

If she randomly pulls six pairs of earrings out of the drawer to take with her on a trip

Number of Possible Outcome =Relative Frequency X Number of Trials

=0.5 X 6

=3

She would most likely take 3 gold earrings.

Value of x after the statement "if P(x) then x 1" is executed where P(x): > 1
ziro4ka [17]

The values of x after the statement are:

  • b) If x=1, then the statement P(1)="1>1" is false, and thus the value of x is equal to 1 after the statement "P(x) then x := 1".
  • c) If x=2, then the statement P(2)="2>1" is true, and thus the value of x is equal to 1 after the statement "if P(x) then x := 1".

<h3>What is Discrete Mathematics?</h3>

This refers to the field of mathematics that studies mathematical structures and views them as discrete, rather than continuous and they include integers, statements, etc.

Therefore, if we consider the statement "if P(x) then x:=1" which is equivalent to "if x>1 then x:=1", then we can see that If x=1, then the statement P(1)="1>1" is false

Gabe​ Amodeo, a nuclear​ physicist, needs 60 liters of a 60​% acid solution. He currently has a 50% solution and a 70% solution.
FromTheMoon [43]

Answer:

Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.

Step-by-step explanation:

Equation:


acid + acid = acid


0.40x + 0.70(60-x) = 0.60*60


40x + 70*60 - 70x = 60*60


-30x = -10*60


x = 20 liters


Gabe needs 20 liters of the 40% solution.  

He also needs 40 liters of the 70% solution.
