If 15/x is equal to 75/100 what is x

Answer: The expression can be T(X) = X/3 + 1 where X is the number of students, and we always should round up our solution if it is not a whole number.

Step-by-step explanation:

She needs a tent for every 3 campers, and she also needs a tent for herself.

This means that if X is the number of campers, we need to have:

T(X) = X/3 + 1

this means that we divide X into groups of 3, and for each group of 3 we have one tent, plus one that we need for the camp leader.

now, if for example we have 10 campers, we will have:

T(10) = 10/3 + 1 = 3.33 + 1

So we will need to round up the number of tents to 4 + 1

The solution of the expression is 48.

Here,

The given expression is;

The quotient of a number and four decreased by ten is two .

We have to find the value of given expression.

What is Mathematical expression?

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Now,

The given expression is;

The quotient of a number and four decreased by ten is two .

Let a number is ''x''.

Then, the quotient of x and four is = x/4

So, the given expression is written as,

x/4 - 10 = 2

x/4 = 10 + 2

x/4 = 12

x = 12 * 4

x = 48

Hence, The solution of the expression is 48.

The below-level floors will be represented by negative numbers and the above level by positive numbers.

An integer is a number whose values are ranges from 0 to infinite positive and zero to infinite negative. A numeral system is a way to convey numbers in writing; it is a way to describe numbers in mathematics by utilizing a consistent collection of digits or other symbols.

Given that a parking garage has floors above and below ground level. For a scavenger hunt, Gaia's friends are given a list of objects ground level is 0 and the first level above ground is 1.

The floors are -3,-4, and 4 because the negative numbers represent below ground as they are below zero and the positive 4 is higher than 1 so which shows that level 4 is higher than level 1.

Therefore, the below-level floors will be represented by negative numbers and the above level by positive numbers.

To determine how much stone Jason will spread on each square yard, one must divide the total amount of stone, which is 3/4 ton, by the number of square yards, which is 3. The result is 1/4 ton of stone per square yard.

Jason has 3/4 ton of stone to spread equally in 3 square yards. To find out how many tons of stone will be spread in each square yard, you divide the total tons by the number of square yards. That gives you:

This calculation shows that Jason will spread 1/4 ton of stone on each square yard.

By definition of squared root of numbers, The square root of fraction of numbers √49 / 144 is,

⇒ √49 / 144 = 7 / 12

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Answer:  the distance between the points R and T is 45 units.

Step-by-step explanation:  We are given to find the distance between the points R and T on the co-ordinate grid.

Distance Formula : The distance between the points (a, b) and (c, d) i given by

[tex]D=\sqrt{(c-a)^2+(d-b)^2}.[/tex]

From the co-ordinate grid, we note that the co-ordinates of point R are (-30, 10) and the co-ordinates of point T are (15, 10).

Therefore, the distance between the points R and T is given by

[tex]D=\sqrt{(15-(-30)^2+(10-10)^2)}=\sqrt{45^2+0^2}=\sqrt{45^2}=45.[/tex]

Thus, the distance bewteen the points R and T is 45 units.

The markup rate of the book is 42 which is 50%.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that a math book at the victor valley college bookstore originally cost $84 to purchase they sell it for $126.

The markup rate will be calculated as,

Markup price = 126 - 84

Markup price = 42

Markup price percentage = 42 / 84 = 0.5x 100= 50%

Therefore, the markup rate of the book is 42 which is 50%.

The graph that represents the equation y = 1.4x +2 is attached in the image.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

The graph that represents the equation y = 1.4x +2 can be plotted on a graph paper by choosing some arbitrary values of x.

When x = 0, y =2. x = 5 , y = 9. x = 10 , y = 16.

This can be put together as ordered pairs (x, y) as (0, 2), (5, 9), (10, 16).
