Solve 2(4x+2)= 4x -12(x-1) the solution is x
The Value of x is -1/2 in this Linear equation
As we have the equation 2(4x+2)= 4x -12(x-1)
2(4x+2)= 4x -12(x-1) 8x + 4 = 4x - 12x + 12................. On opening the brackets8x + 4 = -8x + 1216 x + 4 = 12 ----------------- on subtraction 8x from both the sides( As we can perform any operation in both the sides of equation)16x = 8 -------- On subtracting 4 from both the sidesx= 1/2So we can conclude that the Value of x is 1/2
we can verify the answer by putting back the value of x in the equation and both sides will have the same value.
2(4x+2)= 4x -12(x-1)
2(4*1/2+2)= 4*1/2 -12(1/2-1)

Joseph has a bag filled with 2 red, 4 green, 10 yellow, and 9 purple marbles. Determine P(not green) when choosing one marble from the bag.
The probability that the selected marble will not be green is 21/25.
What is probability?Probability is a measure of how likely something is to occur.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
So, we know that:
The bag contains: 2 red, 4 green, 10 yellow, and 9 purple
Probability formula: P(E) = favourable events/total events
Now, calculate as follows:
P(not green) = 21/25

Answer:

Step-by-step explanation:
Answer: The answer to your question is 60%
Step-by-step explanation: The total number of marbles in Joseph's bag is:
2 (red) + 4 (green) + 10 (yellow) + 9 (purple) = 25
The probability of choosing one marble that is not yellow can be found by dividing the total number of marbles that are not yellow by the total number of marbles in the bag:
P(not yellow) = (2 red + 4 green + 9 purple) / 25
P(not yellow) = 15/25
P(not yellow) = 3/5
P(not yellow) = 0.6 or 60%

ProportionThe heights of things in the photo are presumed to be related to their actual height by the given scale factor.
actual height / photo height = 2.5 ft / (1.5 in)
actual height / 6 in = (2.5 ft)/(1.5 in)
Multiplying by 6 in gives ...

What is the rule of substitution?
In this rule, we have to find the value of any of the variables either first or second and substitute its value in the other equation.
It is best to use the substitution method when equations are either given in form or can be gain into the form of x = ay + b and y = mx + n.
A procedure to answer a system of linear equations in more than two variables algebraically is the substitution method. In this process, we find the value of any one of the variables by alienating it on one side and taking every other term on the other side of the equation.
Then we substitute that first value in the second equation.
The substitution method is one of the algebraic processes to answer simultaneous linear equations. It implies substituting the value of any one of the variables from one equation into the other equation.
And at last, we can put the value of y in any of the given equations to find x.

What 3 lengths make a triangle?
The Triangle Inequality Theorem, which asserts that the sum of a triangle's two side lengths is always greater than the third side, will suffice. You will have a triangle if this holds true for each of the three possibilities of increased side lengths.
Let's use the triangle inequality theorem to examine the characteristics of a triangle's sides.
The two requirements for a triangle's sides are:
(1) The two sides added together are always larger than the third side.
a+b>c
a+c>b
b+c>a
(2) Less exists between the two sides than there does between the third side.
|a-b|<c
|a-c|<b
|b-c|<a
Therefore, if and only if the total of two sides is always larger than the third side and the difference of the two sides is less than the third side, 3 lengths could be the measures of the edges of a triangle.

How to create triangle ?Triangle Properties
A triangle's (of all varieties) total sum of angles is 180°.The length of a triangle's two longest sides added together is longer than the third side.Similar to this, the length of the third side of a triangle's third side is shorter than the difference between its two sides.Any two triangle sides can add up to a length that is longer than the third side. The greatest side of a triangle is the side that faces the largest angle. The sum of the triangle's internal opposing angles is equal to any of its outer angles.
According to the sides of a triangle rule, the lengths of any two sides of a triangle must add up to more than the length of the third side.
Sum of 2 sides each are :

Sam is proving the product property of logarithms. Step justification given substitution which expression and justification completes the third step of her proof? ; power rule of exponents subtraction property of exponents multiplication rule of exponents division property of exponents.
Sam's rationale for the third step based on logarithm properties would be logb(b^x+y), power rule of exponents. Thus, the correct answer is C.
The first step of Sam's proof is to show that logb(MN) is equal to logb(b^x.b^y), which is a substitution of MN for b^x.b^y. This is based on the product property of logarithms, which states that logb(MN) = logb(M) + logb(N) for any positive numbers M and N and any base b, as long as b doesn't equal 1.
The third step of her proof is to simplify logb(b^x.b^y) further by applying the power rule of exponents, which states that:
b^(x+y) = b^x.b^ySo, by substituting b^(x+y) for b^x.b^y, we get:
logb(b^(x+y)) = logb(b^x+y)So, in short, the justification of the third step is based on the power rule of exponents, and it shows that logb(b^x.b^y) can be simplified further to logb(b^x+y).
The answer choice A, logb(b^xy), power rule of exponents, is incorrect because it implies that the third step is to multiply x and y instead of adding them.
This question should be provided with answer choices, which are:
A. logb(b^xy), power rule of exponents.B. logb(b^x-y), subtraction property of exponents.C. logb(b^x+y), power rule of exponents.D. logb(b^x/y), division property of exponents.The correct answer is C.

600=5+60 what was the annual interrest rate
On solving the provided question, annual rate is 2% while doing calculations through simple interest.
What is simple interest?Borrowers must pay simple interest to lenders as a fee for a loan. Compound interest is not taken into account while calculating it; just the principal is used. Simple interest is applicable to all loans. It is also the form of interest that banks give their customers on their savings accounts. Simple interest can be calculated using a simple formula. Simply multiply the loan's principal by the interest rate and the period to get the total. Although some mortgages employ this calculation approach, this type of interest typically relates to auto loans or short-term loans.
Let the annual rate be x%
Principal Amount (p)= $600
Annual Rate (r) = x % (Assumed)
Time (t) = 5 years
Simple Interest (I) = $60
Use the simple interest formula given below:
SI = p×r×t/100
r = 60 ×100/600× 5
r = 2%
Thus, the annual rate of interest is 2 %.
