What is the solution to 8x - 3(2x - 4) = 3(x - 6)?
A.30
B.2
C.6
D.No solution
Answer: A.30
Step-by-step explanation:
Let's solve your equation step-by-step.
8x−3(2x−4)=3(x−6)
Step 1: Simplify both sides of the equation.
8x−3(2x−4)=3(x−6)
8x+(−3)(2x)+(−3)(−4)=(3)(x)+(3)(−6)(Distribute)
8x+−6x+12=3x+−18
(8x+−6x)+(12)=3x−18(Combine Like Terms)
2x+12=3x−18
2x+12=3x−18
Step 2: Subtract 3x from both sides.
2x+12−3x=3x−18−3x
−x+12=−18
Step 3: Subtract 12 from both sides.
−x+12−12=−18−12
−x=−30
Step 4: Divide both sides by -1.
−x/-1 = -30/-1
x=30PLEASE I NEED THIS NOWWWWW

Step-by-step explanation:
A die has 6 faces with numbers 1, 2, 3, 4, 5, 6.
The faces that are less than 3 are 1, 2.
2 faces have numbers less than 2.
The desired outcome can happen 2 ways, 1 or 2.
The total number of possible outcomes is 6: 1, 2, 3, 4, 5, or 6.
p(event) = (number of desired outcomes)/(total number of possible outcomes)
p(less than 3) = 2/6 = 1/3
The probability of rolling a number less than 3 is 1/3.
Now we find 1/3 of 420.
1/3 * 420 = 420/3 = 140

Answer: P(Quarter & Penny): 9/100
p(Two pennies): 9/25
Step-by-step explanation:
There are 20 coins in the bag, so you have a 3/20 chance of getting a quarter, 5/20 chances of getting a dime and 12/20 chance of getting a penny on each draw if the coins are always replaced.
Im this situation, you can simplify the fractions, the
Multiply the chance of each independent event times the chance of the next independent event.
3/20 × 3/5 = 9/100 for the quarter and the penny
3/5 × 3/5 = 9/25 for the two pennies
