Answer:
7
Step-by-step explanation:
5(x - 3) = 2(x + 3) Distribute
5x - 15 = 2x + 6
+ 15 + 15 Switch sides to the liked terms
5x = 2x + 6 + 15
-2x -2x Switch sides to the liked terms
5x - 2x = 6 + 15
3x = 21 Divide
3 3
x = 7
Answer:
x = 7
Step-by-step explanation:
Equation: 5(x-3) = 2(x+3)
Step 1: Simplify the equation.
5 (x − 3) = 2(x + 3)
(5)(x) + (5)(−3) = (2)(x) + (2)(3) Distribute
5x + −15 = 2x + 6
5x − 15 = 2x + 6
Step 2: Subtract 2x.
5x − 15 −2x = 2x + 6 −2x
3x − 15 = 6
Step 3: Add 15.
3x − 15 + 15 = 6 + 15
3x = 21
Step 4: Divide by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex]
Step 5: Divide 21 by 3.
The answer is x = 7.
Three more than twice a number x is 15. Determine the value of x.
Answer:
Pretty sure the answer would be x=6
Step-by-step explanation:
The number (x) in: "3 more than twice a number is 15" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
2x/2 = 12/2
x = 6
Write the expression 12p+48 as a product using GCF (greatest common factor) as one of the factors
Answer:
12(p+4)
Step-by-step explanation:
The greatest common factor of expressions is the highest divisor that can divide both expressions
The equivalent expression of 12p+48 is 12(p - 4)
The expression is given as:
[tex]\mathbf{12p + 48}[/tex]
Express 48 as 12 * 4
[tex]\mathbf{12p + 48 = 12p - 12 \times 4}[/tex]
Express 12p as 12 * p
[tex]\mathbf{12p + 48 = 12 \times p - 12 \times 4}[/tex]
Factor out 12 from the expression on the right-hand side
[tex]\mathbf{12p + 48 = 12 \times (p - 4)}[/tex]
Remove the product sign
[tex]\mathbf{12p + 48 = 12 (p - 4)}[/tex]
Hence, the equivalent expression is 12(p - 4)

Use the divisibility rules to determine which of the following numbers 330 is divisible by. (Check all that apply.)
2
3
5
7
11
The numbers that divide 330 are 2, 3, 5 and 11.
How to find the divisibility for a given number?In order to find divisibility, there are certain rules for different numbers. If a number is divisible by two numbers then it is also divisible by their product.
The given number is 330.
The divisibility rules for the number given can be applied one by one as follows,
Divisibility for 2,
For a number to be divisible by 2 its unit digit must be 0, 2, 4, 6 or 8.
Thus, 330 is divisible by 2.
Divisibility for 3,
For a number to be divisible by 3 sum of the digits of the number must be divisible by 3.
Since sum of the digits of 330 is 6 which is divisible by 3, 330 is also divisible by 3.
Divisibility for 5,
A number should either end with 0 or 5 in order to be divisible by 5.
Thus, 330 is divisible by 5 as it ends with 0.
Divisibility for 7,
For a number to be divisible by 7, the digit at ones place multiplied by 2 and then subtracted from the remaining digits must be divisible by 7.
Here, in 330 this rule is applied as,
33 - 2 × 0 = 33
Since 33 is not divisible by 7, 330 is also not divisible.
Divisibility for 11,
The difference of the sum of the digits at even place to the odd place must either be zero or divisible by 11.
In 330, 3 + 0 - 3 = 0.
Thus, 330 is divisible by 11.
Hence, the given number 330 is divisible by 2, 3, 5 and 11.

Answer: The slope is -2.
Step-by-step explanation:
(2,-3)
(-2,5)
Using the two given points, you can find the slope by finding the difference in the y coordinates and diving it by the difference in the x coordinates.
y coordinates: -3 - 5= -8
x coordinates; 2-(-2) = 4
Slope: -8/ 4 = -2

Find the probability of getting four consecutive aces when four cards are drawn without replacement from a standard deck of 52 playing cards.
Answer:
P=0.0000037
P=0.00037%
Step-by-step explanation:
Probability
A standard deck of 52 playing cards has 4 aces.
The probability of getting one of those aces is
[tex]\displaystyle \frac{4}{52}=\frac{1}{13}[/tex]
Now we got an ace, there are 3 more aces out of 51 cards.
The probability of getting one of those aces is
[tex]\displaystyle \frac{3}{51}=\frac{1}{17}[/tex]
Now we have 2 aces out of 50 cards.
The probability of getting one of those aces is
[tex]\displaystyle \frac{2}{50}=\frac{1}{25}[/tex]
Finally, the probability of getting the remaining ace out of the 49 cards is:
[tex]\displaystyle \frac{1}{49}[/tex]
The probability of getting the four consecutive aces is the product of the above-calculated probabilities:
[tex]\displaystyle P= \frac{1}{13}\cdot\frac{1}{17}\cdot\frac{1}{27}\cdot\frac{1}{49}[/tex]
[tex]\displaystyle P= \frac{1}{270,725}[/tex]
P=0.0000037
P=0.00037%
