Answer:
a = -21
Step-by-step explanation:
-3a +2a -8 = 13
- a-8 = 13
-a -8 -13 = 0 ( the sign changes from +13 to -13 )
-8 -13 = a ( the sign of a changes from -a to + a ) -21 = a

Find the distance between the points R(0, 1) and S(6, 3.5). The exact distance between the two points is .
Answer:
the answer 6.5
........
The distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.
What is a distance formula?It is defined as the formula for finding the distance between two points. It has given the shortest path distance between two points.
The distance formula can be given as:
[tex]\rm d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
It is given that:
Two points are:
R(0, 1) and S(6, 3.5)
To find the distance between points R and S we can use the distance formula.
[tex]\rm d=\sqrt{(6-0)^2+(3.5-1)^2}\\[/tex]
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
d = √(36 + 6.25)
d = √42.25
d = 6.5 units
Thus, the distance between the points R(0, 1) and S(6, 3.5) is 6.5 units after using the distance formula.

Write a couple sentences to explain how you would find the area of the shaded region:
Answer:
I would find the area of the circle and then find the area of the shape in the middle and then minus that from the area of the whole circle
Answer:
Step-by-step explanation:
1. Find the area of the circle. Area_c = pi * r^2
2.Find the area of the pentagon in terms of the radius Area_P =
3 sqrt(3) r^2 / 2
The answer you want is Area_shade = Area_c - area_P
Area = pi * r^2 - 3 sqrt(3)r^2/2
Area = r^2 (pi - 3 sqrt(3)/2)

Let's flip the equation so x is on the left. We want to isolate x to see what it equals.
4x+3=-13
We subtract 3 from both sides.
4x=-16
We divide both sides by 4.
x=-4.

Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = - 4}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 13 = 4x + 3}[/tex]
Swap the sides of the equation
[tex] \longrightarrow{ \sf{4x + 3 = - 13}}[/tex]
Move 3 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{4x = - 13 - 3}}[/tex]
The negative integers are always added but posses the negative ( - ) sign
[tex] \longrightarrow{ \sf{4x = - 16}}[/tex]
Divide both sides by 4
[tex] \longrightarrow{ \sf{ \frac{4x}{4} = \frac{ - 16}{4}}} [/tex]
Calculate

If x = -2, then 2x = -4.
A. Addition Property of Equality
B. Subtraction Property of Equality
C. Multiplication Property of Equality
D. Division Property of Equality
E. I'm not sure.
The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.
Option C is the correct answer.
We have,
The Multiplication Property of Equality states that if you multiply both sides of an equation by the same non-zero number, the equality still holds true.
In this case, x = -2.
Multiply both sides of the equation by 2,
2x = 2(-2) = -4
Thus,
The statement "If x = -2, then 2x = -4" can be demonstrated using the Multiplication Property of Equality.

In triangle ABC, the size of angle B is 5 times the size of angle A, and the size of angle C is 11 degrees less than 4 times the size of angle A.
Find the size of the angles.
Answer:
A = 19.1°
B = 95.5°
C = 65.4°
Step-by-step explanation:
B = 5A
C = 4A-11
We know that a triangle has a total of 180° so:
180 = A + B + C
Which can be written as:
180 = A + (5A) + (4A - 11)
180 = 10A - 11
10A = 191
A = 19.1°
With A, we can work out B and C:
B = 5(19.1)
B = 95.5°
C = 4(19.1) - 11
C = 76.4 - 11
C = 65.4°
What is the slope of the line ?
Answer:
The slope of a line characterizes the direction of a line.
Step-by-step explanation:
To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. also You can determine the slope of a line from its graph by looking at the rise and run. One characteristic of a line is that its slope is constant all the way along it. So, you can choose any 2 points along the graph of the line to figure out the slope.

please solve 5p-9=2p+12
The required solution to the equation 5p - 9 = 2p + 12 is p = 7, as of the given condition.
To solve the equation 5p - 9 = 2p + 12, we will follow these steps:
Combine like terms on each side of the equation:
5p - 9 = 2p + 12
Move all the terms containing "p" to one side and the constant terms to the other side. To do this, we'll subtract 2p from both sides and add 9 to both sides:
5p - 2p - 9 + 9 = 2p + 12 - 2p + 9
Simplifying both sides:
3p = 21
Now, to solve for "p," we'll divide both sides of the equation by 3:
3p/3 = 21/3
Simplifying:
p = 7
Therefore, the solution to the equation 5p - 9 = 2p + 12 is p = 7.
