Answer:
6 or 5
Step-by-step explanation:
The value of x is 8.366, y is 4.582 and z is 5.477.
Using Pythagoras theorem in both Triangle as
Triangle 1:
H² = P² + B²
z²= y² + 3²
z² = y² + 9
Triangle 2:
x² = y² + 7²
x² = y² + 49
and, x² = z² - 9 + 49
x² = z² + 40.............(1)
Now, In big Triangle
x² + z² = 10²
x² + z² = 100
Now, from equation (1) we get
z² + 40 + z² = 100
2z² = 60
z² = 30
z = 5.477
and, x²= 30+40 = 70
x= 8.366
and, y²= z² - 9
y² = 21
y= 4.582

System of EquationsA system of equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point of the intersection.
You can solve a system of equations by the adding or substitution methods. In the addition method, you eliminate a variable, on the other hand, in the substitution method you replace a variable for the other.
First, you should convert the text of the question into a math expression. Then,
Javier pagó $92 por 5 libretas y 3 lápices. You can represent this text as the equation:5B+3L=92, where B= libretas and L=lápices.
Laura compró 2 libretas y 6 lápices, y pagó $56. You can represent this text as the equation:2B+6L=56, where B= libretas and L=lápices.
Therefore,
5B+3L=92 (1)
2B+6L=56 (2)
After that, you should multiply equation(1) by -2. Thus,
-10B-6L=-184(1)
2B+6L=56 (2)
Now, when you sum equations 1 and 2, you eliminate L . Thus, from this sum, you will have:
-8B=-128
B=128/8
B=16
If B=16, from equation 2, you can find L.
2B+6L=56 (2)
2*16+6L=56
32+6L=56
6L=56-32
6L=24
L=4

|x-1| + 5 = 2
Answer: x has no solutions
Step-by-step explanation:
|x-1| + 5 = 2
|x-1| + 5 - 5 = 2-5
|x-1| + 5 - 5 = -3
|x-1| = -3 ==> Absolute value functions can't be negative. Hence, there is no solution.
x has no solutions

Select all the true statements.
A) Triangle STU is isosceles.
B) Triangle STU is equilateral.
C) Each side of triangle STU is composed of two radii that have the same
length.
D) In triangle STU, two sides are radii of circle T but the third side, segment
SU, is not a radius of any circle shown in the diagram.
☐E) Triangle VWZ is equilateral.
OF) Each side of triangle VWZ is composed of two radii that have the same
length.
The true statements are: (A), (D), (E) and (F).
Statement A is true. A triangle is said to be isosceles if its two sides are of equal length. Considering the triangle STU, the sides ST and TU are the radius of the same circle centered at T and hence of same length. So triangle STU is isosceles.
Statement B is false. In triangle STU, ST and TU being radii of circle T, are equal. But the third side SU is not a radius of any circle in the diagram and so not equal to ST and TU. Since three sides are not of same length, triangle STU is not an equilateral triangle.
Statement C is false. In Triangle STU two sides are composed of a single radii and not of two radii. The third side is not composed of radii.
Statement D is true. In triangle STU, two sides are radii of circle T but the third side, segment SU, is not a radius of any circle shown in the diagram.
Statement E is true. In triangle VWZ, each side is composed of 2 radii which are of same length. Hence three sides are equal and so it is an equilateral triangle.
Statement F is true. Each side of triangle VWZ is composed of two radii that have the same length.

Tthe difference of depths between them is 1 foot, and the trench which is deeper is the Japan Trench
What is the difference of depths between them, and which trench is deeper?The depths of the trenches are given as
Japan Trench = 9 km below sea level
Peru-Chile Trench = 8 km below sea level
Both trenches are below the sea level
This means that the deeper trench will have the higher absolute value
The trench with the higher absolute value is the Japan Trench
This is so because 9 is greater than 8
The difference of depths between the trenches is

32+(-17) is 17 units from 32, in the positive direction
On the number line, It is true to the claim that the solution to the expression 32 + (-17) is 17 units from 32 in the positive direction.
What is a number line?A number line is an illustration of a graded straight line that represents actual numbers. What we call a "number line" is really a horizontal line with regularly spaced number increments. The number line's response format is determined by the numbers it contains.
All possible numbers may be plotted along a line called a number line. Any real number may be represented by a single dot on a number line.
On the number line, we have the negative numbers on the -ve x-axis to the left and they are smaller than the positive numbers to the right, and this is immediately apparent when looking at a number line.
Given that:
= 32 + (-17)
= 32 - 17
= 17
We can therefore conclude that the given expression shows that we are 17 units far away from 32 in the positive x-axis on the number line.

Question 3: A family is traveling in their RV all summer. They have several propane tanks on their RV. Propane is safe to use between temperatures of −40° F and 120° F.
Write an inequality to represent the temperatures at which the propane is safe to use.
The inequality to represent the temperatures at which the propane is safe to use is -40 < x < 120.
It is said that it is safe to use Propane between the temperatures of -40°C and 120°C.
We already know the use of an equality. It makes the values on both sides of it equivalent.
An inequality compares the values on both sides of it. It informs us which one is greater than or less than the other or if they are equal. That is, inequality has a possibility for equality too.
Here the minimum temperature at which propane is safe to use = -40°C
The maximum temperature at which Propane is safe to use = 120°C
We take a variable 'x' to denote the safe temperature of Propane.
Then according to the information, the inequality to represent the temperatures at which the propane is safe to use is,
