What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n"  ways; then the two events in succession can occur in m × n  ways.

Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.

Pencil = 21

Pencil holder = 3

Therefore, we will do as 21 divided by 3

21/3 = 7

Hence, there are 7 pencils in each pencil holder.

x is less than or equal to 3. What is the interval notation

Answers

Answer:

Step-by-step explanation:

Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .

The statement in the mathematical form will be x ≤ 3. Then the inequality in the interval notation will be [3, ∞).

What is inequality?

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

x is less than or equal to 3.

Convert the statement into a mathematical inequality. Then we have

x ≤ 3

The statement "x is less than or equal to 3" in the mathematical form will be x ≤ 3.

Thus, the inequality in the interval notation will be [3, ∞).

Find the value of x and
y if x-y=3 and 2x+3y=4​

Answers

Answer:

Step-by-step explanation:

Given :

x-y = 3                                equation(i)

2x + 3y = 4                           equation(ii)

Now,

x - y = 3

x = 3 + y

substitute the value of x in equation (ii)

2x + 3y = 4

2(3 + y) + 3y = 4

6 + 2y + 3y = 4

6 + 5y = 4

y = -2/5

x-y=3

2x+3y=4

Using elimination we can multiply the top equation by -2 to Eliminate the x values. Doing this gives us

-2(x-y)= -2(3)

Simplifying we have

-2x+2y=-6
And then adding the second equation, we can have a system of two equations where the x eliminates

-2x+2y=-6
+2x+3y=+4

Adding we get that

5y=-2

Dividing by 5 on both sides gives us y=-2/5

We can substitute this y term in for the first equation. Doing so we have

x-(-2/5)=3

using the a-(-b)=a+b rule we get

x+2/5=3

Thus x=3- 2/5

So using a calculator we can say that x=13/5.

Thus your answers are x=13/5 and y=-2/5

What is Simplification?

Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.

Given, the values of a and b are 9/11 and 7/10 respectively

thus,

ab = 9/11 * 7/10

simplifying it

ab = 63/110

Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10

When you square or cube a negative number is it still negative or does it become positive?

Example:
(-4)^{2}

Answers

When you square a negative number, the result is positive.
(-4)^2 = (-4)ª(-4) = 16

When you cube a negative number, the result is negative.
(-4)^3 = (-4)•(-4)•(-4) = -64

Negatives pair up and cancel out, so odd exponents always have one negative unpaired, making the result negative.
