The value of unknown number n is 47, wrote by Ms. Morales.

<h3>What is defined by the term expression?</h3>

In mathematics, an expression is a sentence that contains at least two digits or variables and with at least each math operation.

Addition, simple arithmetic, multiplication, or division are all examples of math operations.

a) Constant: a numerical value that is fixed.
b) Variables: they have no fixed values. Values are assigned based on the requirement.
c) Terms: could be constants, variables, or variables multiplied by constants/ (s). Each word in an expression is denoted by a '+' or '-' sign.

For, the given condition in question;

Ms. Morales wrote the sum of 5 copies of some number n.

Then again,

He again wrote 2 copies of the same unknown number n.

The expression becomes;

n = 42 + 5

n = 47

Thus, the value of the unknown value is found as 47.

A rectangular prism has a length of 12 in., a width of 5 in., and a height of 414 in.

Dafna11 [192]

Answer:

16320 cubes are needed to fill the rectangular prism.

Step-by-step explanation:

Given : A rectangular prism has a length of 12 in., a width of 5 in., and a height of $4\frac{1}{4}$ in.

The prism is filled with cubes that have edge lengths of $\frac{1}{4}$ in.

To find : How many cubes are needed to fill the rectangular prism?

Solution :

A rectangular prism has

Length of 12 in.

Width of 5 in.

Height of $4\frac{1}{4}=\frac{17}{4}$ in.

Volume of rectangular prism is $V=L\times B\times H$

$V=12\times 5\times \frac{17}{4}$

$V=255 in^3$

A cube has length of $\frac{1}{4}$ in.

Volume of cube is $V=L^3$

$V=\frac{1}{4}^3$

$V=\frac{1}{64}in^3$

Cubes are needed to fill the rectangular prism is

$=\frac{\text{Volume of rectangular prism}}{\text{Volume of cubes}}$

$=\frac{255}{\frac{1}{64}}$

$=255\times 64$

$=16320$

Therefore, 16320 cubes are needed to fill the rectangular prism.

AnnyKZ [126]

Consider the expression $0.09(75h) + 75h.$

If h represents the number of hours it takes to repair the computer, then expression 75h represents the amount of money that repairer earns.

The expression 0.09(75h) represents the amount of money for tax Mrs. Bull has to pay. This means that tax makes up 9%.

Answer: first part 0.09(75h) represents the amount of money for tax Mrs. Bull has to pay.

Which equation represents a line which is parallel to the line y=5/6x−7?

lyudmila [28]

Answer: The choice will be any equation where the slope is the same and the y-intercept is different.

$y=\frac{5}{6}x + b$

Step-by-step explanation: Using slope-intercept form, y = mx + b,

m is the slope, b is the y-intercept.

Parallel lines will have the same slope.

So, you are looking for another equation that has 5/6 as the coefficient of x.

It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.
