Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.
Answers
Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)
Divide the product of 5 and 8 by 4

Divide the product of 5 and 8 by 4 gives 10.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.
Division can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
Thus, a ÷ b = a divided in b equal parts.
We have to Divide the product of 5 and 8 by 4
So, Product; 5 x 8 = 40
Now divide by 4;
40 ÷ 4 = 10
Hence, Divide the product of 5 and 8 by 4 gives 10.

Find the mean of the integers: 17, -25, 3, -29, -15, 7
Answers
Answer: -7
Step-by-step explanation: To find the mean, here is the equation =
Divide the sum of all values in a data set ÷ the number of values = mean (average)
Step 1 :
So we do =
17 + -25 + 3 + -29 + -15 + 7 = -42
So the sum of the integers is -42
Step 2 :
We divide the sum by the number of values.
17, -25, 3, -29, -15, 7
1 2 3 4 5 6
So there are 6 values.
We do =
-42 ÷ 6 = -7
So the mean (average) of these integers is -7

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
Answers
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.

Brainlist for positive attitude and correct answer :D
Answers
Answer: The correct answer is:
Probability of rolling a number less than 3: 2/6 or 1/3
Step-by-step explanation:
Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.
Probability of not rolling a number less than 3: 4/6 or 2/3.
Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D
