Answer:
n = 9
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
3n - 5 = 22
Step 2: Solve for n
Add 5 to both sides: 3n = 27Divide 3 on both sides: n = 9If you have a decimal answer, round to the nearest tenth!
8n−6=2n+13
Answer:
n = 3.17
Step-by-step explanation:
Given:
8n − 6 = 2n + 13
Collect like terms
8n - 2n = 13 + 6
6n = 19
Divide both sides by 6
n = 19/6
= 3.167
Approximately to the nearest tenth
n = 3.17

34% of 65. Do not round!!! pls help
Answer:
22.1
Step-by-step explanation:
If we put 65 over 100 and x over 34 and do cross multiplication, we see that 65 times 34 is 2,210. Dividing 100 from both sides of the equation, we divide 100 from x and 100 from 2,210. We are left with X = 22.1

What is the area of the triangle in the in the diagram?
Answer:
no tengo ni idea
Step-by-step explanation:
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.
What is the area of the triangle?Assume 'h' is the height of the triangle and 'b' be the base of the triangle. Then the area of the triangle is given as,
A = (1/2) × h·b
The coordinates of the triangle will be (x₁, y₁), (x₂, y₂), and (0, 0).
The length of the base of the triangle will be given as,
Base = (x₂ - x₁)
The height of the triangle is given as,
Height = (y₂ - 0) or (y₁ - 0)
Height = y₂ or y₁
The area of the triangle will be given as,
A = (1/2) × (x₂ - x₁) × y₁
A = (1/2) y₁(x₂ - x₁)
The area of the triangle will be A = (1/2) y₁(x₂ - x₁). Then the correct option is B.

through (2, -4) and parallel to y= 9/2x+3
Answer:
y=[tex]\frac{9}{2\\}[/tex] x-13
Step-by-step explanation:
first, since it's parallel the slope has to be the same and the y-intercept has to be different.
you will have y=9/2x+b
find b, by using the points you are given so you will get
-4=(9/2) times (2)+b.
then when sloving you will get b=-13 and so the full equation will be
y=9/2x-13

Good luck on the test BTW. =)
The correct answer is option B which is the hourly pay usually increases with the work experience.
What is a scatter plot?Scatter plots are graphs that show how two variables in a data collection relate to one another. On a two-dimensional plane or in a Cartesian system, it represents data points.
In the given graph horizontal axis contains the years of experience and the vertical axis consists of the hourly pay of an employee. We can see that the employees with higher experience are paid a higher hourly amount.
Therefore the correct answer is option B which is the hourly pay usually increases with the work experience.
