Answer:

r - d/t

Step-by-step explanation:

Given d = r*t, solve for r:

To isolate r on the right side of this equation, divide both sides by t.  This results in

r = d/t

Answer:

r=\frac{d}{t}

Step-by-step explanation:

We have been given a formula d=rt, which means that the distance traveled is equal to the rate (speed) times the time.

To solve the given equation for r, we will divide both sides of our equation by 't' as shown below:

\frac{d}{t}=\frac{rt}{t}

\frac{d}{t}=r

Switch sides:

r=\frac{d}{t}

Therefore, our required equation would be r=\frac{d}{t}.

There are 4 books on a shelf. books are added to the shelf at a rate of 2 books per minute. the total number of books on the she
Bad White [126]

The algebraic equation to represent the given situation is as follows,

y = 4 + 2x

What is an algebraic equation?

The term "algebraic equation" refers to a formulation of the equality of two expressions using the algebraic operations of addition, subtraction, multiplication, division, raising to a power, and extraction of a root on a set of variables.

An expression that includes variables, constants, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, etc.).

Forming the Algebraic Equation

Number of book present on the shelf initially = 4

It is given that 2 books are added per minute to the shelf.

If x is the number of minutes, then the books added will be 2x.

If y is the total number of books present on the shelf, then the algebraic equation is given as,

y = Number of books initially present on the shelf  + 2x

⇒ y = 4 + 2x

Thus, y = 4 + 2x is the required algebraic equation.

(80 POINTS) What rule describes a dilation with a scale factor of ½ and the center of dilation at the origin?
lesya [120]

Answer:

C

Step-by-step explanation:

(x, y) -> (1/2x, 1/2y)

When you dilate a side, point, etc, you are multiplying the original dimension by the scale factor. That is represented in option C: the original x and y are multiplied by the scale factor, 1/2! Hope that helps! :)

Find two numbers if their sum is 6.1 and their difference is 1.6
Nimfa-mama [501]
A+b=6.1 ---(1)
a-b=1.6 ---(2)

(1)+(2); 2a=7.7
then a=3.85
so b=a-1.6 = 3.85-1.6 = 2.25

so that the two numbers are 2.25 and 3.85

10 increased by the quotient of a number and 6 is 15
Makovka662 [10]
<h2>Verbal Phrase to Mathematical Phrase</h2><h3>Answer:</h3>

10 +\frac{n}{6} = 15\\

<h3>Step-by-step explanation:</h3>

Let that number be n.

The quotient of a number and 6 is \frac{n}{6}\\.

"Increased" is just another term for "plus (+)" so 10 increased by The quotient of a number and 6 is 10 + \frac{n}{6}\\

And it tells us that it is 15 so it must be 10 +\frac{n}{6} = 15\\
