how do I solve this problem −24−18p=38p?
To solve the equation
-24 - 18p = 38p, add 18p to both sides to combine like terms, then divide by 56 to isolate p, resulting in p = -3/7.
To solve the algebraic equation
-24 - 18p = 38p, we need to isolate the variable p on one side of the equation. Here's a step-by-step solution:
Combine like terms by getting all the terms containing p on one side of the equation. To do this, add 18p to both sides:
-24 - 18p + 18p = 38p + 18p
-24 = 56p
Now divide both sides by 56 to solve for p:
-24 / 56 = 56p / 56
-3/7 = p
The solution to the equation is p = -3/7.

How do you write 6.67 × 102 in standard form
Standard form refers to the regular way you write out a number, such as 4,300, as opposed to scientific notation, which is 4.3 x 10^3, or in expanded form, such as 4,000 + 300. You can convert numbers large and small to standard form in a few steps.
STANDARD FORM WITH LARGE NUMBERSTo convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:
10 x 10 x 10 x 10 = 10, 000
Plug the product -- which is 10,000 -- into the original equation to get this:
1.5625 x 10,000 = 15, 625
Therefore, the standard form of this number is 15,625.
For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:
10,000 + 2,000 + 100 + 10 + 9 = 12,119
Therefore, the standard form of the number is 12,119.
STANDARD FORM WITH SMALL NUMBERSSmall numbers, such as those less than one, can also be converted to standard form. For example, consider the scientific notation 5 x 10^-2. Start with 10^-2, and note that the exponent is negative, which in this case, is negative two. This indicates that the number will be a decimal, with the decimal point moving twice to the left of the base number, which in this case, is 10. This would give you 0.01. Your equation will look like this:
10^2-1 = 0.01
Plug in this value, which, in this case is 0.01, into your original equation to get this:
5 x 0.01 = 0.05
Therefore, the standard form of this number is 0.05.
Convert small numbers presented in expanded form, such as 0.0003 + 0.001 + 0.02 by adding like this:
0.0003 + 0.001 + 0.02 = 0.0213

Part 1:Is it possible for a composite number to have more than one prime factorization? Is it possible for a number to have no prime factors? Why?
Part 2: Give an example of how prime factorization could be used in the real world.
There is only 1 set of prime factors for any number
A prime number can be divided evenly only by 1 or
itself, so it would not have any prime factors
Part 2
Prime factorization is used by people who try to make or break secret codes made with numbers, because factoring really large numbers is difficult and can take computers a long time to do it.
Answer:
Part 1:Is it possible for a composite number to have more than one prime factorization?
Answer: No.
Is it possible for a number to have no prime factors? Why?
Answer: Yes. The number 1 has no prime factors, and 1 is not prime.
Part 2: Give an example of how prime factorization could be used in the real world.

the line parallel to x-3y=-12 that passes through (-3,4)
The equation of the line parallel to x-3y=-12 that passes through (-3,4) is y=x/3+5.
What is the standard equation of a line?The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
The line function equation is
x - 3y = -12
y = (1/3)x +4
When a line is parallel to another line, the slope of the lines is same.
So, the slope of the line parallel to the line x - 3y = -12 is 1/3
y = (1/3)x +c
As the line passes through the point (-3,4)
4 = (1/3) * (-3) +c
4 = -1 +c
c = 5
The equation is
y=x/3+5

13 tenths+8 tenths+32 hundredths
The value of 13 tenths + 8 tenths + 32 hundredths is 2.42.
Here's how we can break it down:
Convert tenths and hundredths to decimals:
13 tenths = 13/10 = 1.3
8 tenths = 8/10 = 0.8
32 hundredths = 32/100 = 0.32
Add the decimal values:
1.3 + 0.8 + 0.32 = 2.42
Therefore, 13 tenths + 8 tenths + 32 hundredths equals 2.42.

The length and width of a rectangle quadruple what happens to the area is to be determined.
the rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.
What is surface area?Surface area is defined as the area of the surface that is uncovered.
Here,
The length(L) = 4 L
The width (W) = 4W
area of the rectangle = length * width = LW
The new area of the rectangle = 4L * 4W

Thus, to find the unit rate that represents number of pages to be read by Shaun in 1 hour,
let x = number of pages read in 1 hour.
The following proportion would be created:
60 pages = 3/4 h
x pages = 1 h
Cross multiply[tex]\frac{3}{4} \times x = 1 \times 60\\\\\frac{3x}{4} = 60[/tex]

David was given $0.75.
David was given $0.26.
One coin is smaller in size than the other
David was given $0.15.
Final answer:
The statement 'David was given $0.26' is not true because U.S. currency does not include the necessary coins where one coin is twice the value of the other to make up $0.26.
Explanation:
David was given two coins, where one coin is worth twice the value of the other. We need to identify which statement is not true among the given options regarding the value of the coins David was given. Let's analyze each statement:
Only the statement about being given $0.26 cannot be true, because U.S. currency does not include the necessary coins to satisfy the condition where one coin is twice the value of the other.

The equation of the line in point-slope form that passes through (-2, -6) and has a slope of 13 is y + 6 = 13(x + 2).
Explanation:The equation of a line in point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
To find the equation of the line that passes through (-2, -6) and has a slope of 13, we can substitute the values into the formula:
y - (-6) = 13(x - (-2))
Simplifying this equation, we get y + 6 = 13(x + 2). Therefore, the correct equation of the line in point-slope form is y + 6 = 13(x + 2).
