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

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

Answer:
30
Step-by-step explanation:
Add all the measures 50+35+85+65+60= 210
subtract 180 from 210 and you get
210-180 = 30
we use 180 because Example: Angles on one side of a straight line always add to 180 degrees. 30° + 150° = 180° When a line is split into 2 and we know one angle, we can always find the other one.

Brad has a garden with dimensions 12 feet long x 7 feet wide. He wants to enlarge the garden to an area of 119 square feet. How much farther will he need to extend the length of the garden to attain his desired
Answer:
the length will need to be increased by 5 feet
He will need to 5 feet extend the length of the garden to attain his desired.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Brad has a garden with dimensions 12 feet long x 7 feet wide.
And, He wants to enlarge the garden to an area of 119 square feet.
Now,
Let the number of additional feet added to the length = x
So, We can formulate;
⇒ 7 (12 + x) = 119
⇒ 84 + 7x = 119
⇒ 7x = 119 - 84
⇒ 7x = 35
⇒ x = 5
Thus, He will need to 5 feet extend the length of the garden to attain his desired.
