Answer:
The square root of 3 is an irrational number if that's what you were asking
x = -4z - 19
y= 5x + z - 4
-5y - z = 25
Answer:
x = 1, y = -4, z = -5
Step-by-step explanation:
Solve the following system:
{x = -4 z - 19 | (equation 1)
{y = z + 5 x - 4 | (equation 2)
{-z - 5 y = 25 | (equation 3)
Express the system in standard form:
{x + 0 y + 4 z = -19 | (equation 1)
{-(5 x) + y - z = -4 | (equation 2)
{0 x - 5 y - z = 25 | (equation 3)
Swap equation 1 with equation 2:
{-(5 x) + y - z = -4 | (equation 1)
{x + 0 y + 4 z = -19 | (equation 2)
{0 x - 5 y - z = 25 | (equation 3)
Add 1/5 × (equation 1) to equation 2:
{-(5 x) + y - z = -4 | (equation 1)
{0 x + y/5 + (19 z)/5 = -99/5 | (equation 2)
{0 x - 5 y - z = 25 | (equation 3)
Multiply equation 2 by 5:
{-(5 x) + y - z = -4 | (equation 1)
{0 x + y + 19 z = -99 | (equation 2)
{0 x - 5 y - z = 25 | (equation 3)
Swap equation 2 with equation 3:
{-(5 x) + y - z = -4 | (equation 1)
{0 x - 5 y - z = 25 | (equation 2)
{0 x + y + 19 z = -99 | (equation 3)
Add 1/5 × (equation 2) to equation 3:
{-(5 x) + y - z = -4 | (equation 1)
{0 x - 5 y - z = 25 | (equation 2)
{0 x + 0 y + (94 z)/5 = -94 | (equation 3)
Multiply equation 3 by 5/94:
{-(5 x) + y - z = -4 | (equation 1)
{0 x - 5 y - z = 25 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)
Add equation 3 to equation 2:
{-(5 x) + y - z = -4 | (equation 1)
{0 x - 5 y + 0 z = 20 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)
Divide equation 2 by -5:
{-(5 x) + y - z = -4 | (equation 1)
{0 x + y + 0 z = -4 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)
Subtract equation 2 from equation 1:
{-(5 x) + 0 y - z = 0 | (equation 1)
{0 x + y + 0 z = -4 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)
Add equation 3 to equation 1:
{-(5 x) + 0 y + 0 z = -5 | (equation 1)
{0 x + y + 0 z = -4 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)
Divide equation 1 by -5:
{x + 0 y + 0 z = 1 | (equation 1)
{0 x + y + 0 z = -4 | (equation 2)
{0 x + 0 y + z = -5 | (equation 3)

Write as an inequality. Do not solve.
Yellow Cab charges a flat rate of $3.00 plus $0.50 per mile. Raven
has $20.00 to spend on a cab ride. Write an inequality that expresses how
many miles Raven can travel under her limit.
The product of 8 and y is less than 21.
Raven can travel 5.71 miles or less under her limit.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions. If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality.
Let x b the number of miles Raven travels, we can write an expression relating the amount he spends. So there:
3.00 + 0.50= 3.50
Consider that total cost per mile be less than equal to the amount the Raven can spend:
3.50x ≤ 20
We can determine x;
x ≤ 5.71
Therefore, Raven can travel 5.71 or less under her limit.

a. Which information is not needed to compute the bill after tax and tip?
b. What was the total bill?
well, the bill was actually "x", which oddly enough is the 100%, but we also know that the tip was $1.05 and that's 15% of the whole bill plus tax.
so if we know that 1.05 is 15% of "x", what the dickens is "x"?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 1.05 & 15\\ x& 100 \end{array} \implies \cfrac{1.05}{x}~~=~~\cfrac{15}{100} \\\\\\ 105=15x\implies \cfrac{105}{15}=x\implies 7=x[/tex]
well, as you can see, we know the tax was 8%, but, it doesn't really matter if it had been 25% or who knows, so long we know that 1.05 is 15% of the whole smack.

About Right triangle's
The formula for a right triangle's area, perimeter, and hypotenuse length are all included in the formula for a right triangle.
In geometry, there are several figure kinds that are distinguished from one another by their unique characteristics. A triangle is one of the shapes they frequently use. A triangle is a closed, three-sided polygonal shape. It has three vertices and three sides that contain the triangle's three interior angles. A triangle's three inner angles always add up to 180 degrees.
Equilateral, isosceles, scalene and right-angled triangles are the most typical triangle types we examine. The right triangle formula, commonly known as the right-angled triangle formulae, will be discussed in this section.
Any interior angle that is 90 degrees in length is said to be in a right triangle. It should be remembered that only one of the three angles may be a right angle because the total interior angle of a triangle is 180 degrees.
Continue reading: Right Angle Triangle
The triangle is referred to as an isosceles right-angled triangle if the other two angles are equal, or 45 degrees each. A scalene right-angled triangle, on the other hand, results from the other two angles being uneven.
Trigonometry is where right-angled triangles are used the most frequently. In reality, trigonometry's foundation is the relationship between its angles and sides.

Mrs. Gomez earns $19.50 per hour and gets a 5% raise. Use compatible numbers to estimate her new hourly rate.
The new hourly rate using compatible numbers is $21.
Given,
The earnings of Mrs. Gomez = $19.50 per hour
She gets a raise of 5%
We have to estimate her new hourly rate by using compatible numbers.
Compatible numbers:
Compatibility in mathematics refers to the mental ease with which a number can be added, subtracted, multiplied, or divided. Compatibility refers to the proximity of the compatible numbers to the real numbers, which facilitates estimation of the solution and simplifies problem-solving.
So,
Compatible number of 19.50 is 20.
The amount raised = 20 × 5/100 = 5/5 = $1

Is it possible for consecutive interior angles to be congruent?
No, It is not possible for consecutive interior angles to be congruent.
If the transversal line crosses the two lines as parallel to one another, the consecutive interior angles are supplementary rather than congruent and add up to 180 degrees.
Parallel internal angles are additional (the consecutive interior angles postulate) External angles that follow each other are supplemental (the consecutive exterior angles theorem) Congruent alternate interior angles (the alternate interior angles theorem)
What are consecutive interior angles?The pair of non-adjacent internal angles that are located on the same side of the transversal are referred to as consecutive interior angles.
