Distributive Property
x +3> -8
Can you help please also you need to see what it’s greater then or less than too.
Answer:
x > -11
Step-by-step explanation:
Step 1: Write inequality
x + 3 > -8
Step 2: Solve for x
Subtract 3 on both sides: x > -11Here, the inequality is saying that any number greater than -11 will work as a solution.

A company earns $150 a week for 9 weeks. It then has a loss of 565 a week for 25 weeks. At the end of the 34 weeks what is the company's
balance?
Answer:
54
Step-by-step explanation:
multiply 9 and 7 which is 63. then multiply 63 by 150 which is 9,450. then multiply 25 and 7 which is 175. then divide 175 and 9,450. and the answer is 54. Yw!!
We need to write and solve an algebraic equation to find the final company's balance.
The answer is: The final balance is -$275.
Let's see how to get that.
First, we know that the company earns $150 per week for 9 weeks, then the total amount of money that the company earns in these 9 weeks is:
$150*9 = $1,350
Then the company losses $65 per week for 25 weeks, then the amount that the company losses is:
$65*25 = $1,625
The final balance will be the difference between what the company earned and what the company lost, then the final balance is:
balance = $1,350 - $1,625 = -$275
This means that the company's final balance is -$275.

There were 350 tickets sold for the spring concert at the local high school. Adult tickets cost $4.00 each, student tickets cost $2.50 each, and senior tickets cost $2.00 each. There were 40 fewer senior tickets sold than student tickets. If a total of$1,095 was collected from tickets, write the linear systems that could be used to find the number of each type of ticket sold
Answer:
[tex]\left\{ \begin{array}{ll} a+s+r=350 \\ 4a+2.5s+2r=1095\\r=s-40 \end{array} \right.[/tex]
Step-by-step explanation:
Let's define our variables. Let a represent the number of adult tickets sold, s represent the number of senior tickets sold, and r represent the number of senior tickets sold.
We know that a total of 350 tickets were sold. So, the number of adult, student, and senior tickets sold must total 350. Therefore, we can write the following equation:
[tex]a+s+r=350[/tex]
We know that each adult ticket costs $4, each student ticket costs $2.50, and each senior ticket costs $2. We are given that a total of $1095 was collected. Therefore, the number of tickets multiplied by their respective price must equal $1095. So, we can write the following equation:
[tex]4a+2.5s+2r=1095[/tex]
Finally, we know that 40 fewer senior tickets were sold than student tickets. So, however many students tickets were sold, we can subtract 40 to get the number of senior tickets sold. Therefore:
[tex]r=s-40[/tex]
So, our system of equations is:
[tex]\left\{ \begin{array}{ll} a+s+r=350 \\ 4a+2.5s+2r=1095\\r=s-40 \end{array} \right.[/tex]

Hailey signed up for a streaming music service that costs $14 per month. The service allows Hailey to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $1.50 per song. How much total money would Hailey have to pay in a month in which she downloaded 40 songs? How much would she have to pay if she downloaded ss songs?
Answer:
The given data can be written in the form of an AP, where n is the number of songs Hailey downloads
song_bill(n) = 14 + n(1.50)
Money Hailey has to pay after downloading 40 songs:
n = 40
song_bill(40) = 14 + 40(1.5)
song_bill(40) = 14 + 60
song_bill(40) = 74 dollars
Money Hailey has to pay after downloading ss songs:
n = ss
song_bill(ss) = 14 + ss(1.5)
song_bill(ss) = 14 + 1.5(ss) dollars

8x + 6y = 28
9x + 3y = 39
Set to equal y.
8x + 6y = 28
6y = -8x + 28
y = -8/6x + 28/6
y = -4/3x + 14/3
9x + 3y = 39
3y = -9x + 39
y = -9/3x + 39/3
y = -3x + 13
Set equal to each other.
-4/3x + 14/3 = -3x + 13
Combine like terms.
5/3x = 25/3
Multiply by 3/5
x = 5
Plug x in.
y = -3(5) + 13
y = -15 + 13
y = -2

-2x - 9y = -3
-7x - 9y= -33
Set equal to y.

y = -2/9x + 3/9
y = -2/9x + 1/3
-7x - 9y= -33
-9y = 7x - 33
y = -7/9x + 33/9
y = -7/9x + 11/3
Set equal to each other
-2/9x + 1/3 = -2/9x + 1/3

find the perimeter of the figure below composed of a rectangle and a semi circle round to the nearest tenths place
Given parameters:
We have two shapes, the rectangle and semi circle;
The problem is to find the perimeter of the shape given
The perimeter of a body is the total length of the body.
Here, it is the sum of the perimeter of the rectangle and semi-circle.
Note, to remove repetition, we to deduct 6 which is a common point to both of them.
Perimeter of a semi-circle = Circumference of semi- circle
= πr² x [tex]\frac{1}{2}[/tex]
The diameter here is 6 and radius is 3;
Circumference of semi-circle = π x 3² x [tex]\frac{1}{2}[/tex] = 14.14
Perimeter of rectangle = 2(6+8) = 28
The perimeter of the figure = 14.14 + 28 - 6 = 36.1
The perimeter of the figure is 36.1

If m∠7 = 55°, which of the following statements are true? Select all that apply. There are two horizontal parallel lines are cut by a transversal. The top left angle is denoted by 1 when transversal line makes an angle with upper horizontal line. The supplementary angle of angle 1 (which is top right angle) is denoted by 2 and opposite angle is denoted by 4. The remaining angle is denoted by 3. The corresponding angle of 1 is denoted by 5 and the corresponding angle of 2 is denoted by 6. The opposite angle of 5 is denoted by 8 and opposite angle of 6 denoted by 7. A. m∠6 = 55° B. m∠5 = 135° C. m∠1 + m∠4 = 250° D. m∠1 + m∠6 = m∠7 + m∠4
Answer:
The true statements are;
A. m∠6 = 55°
C. m∠1 + m∠4 = 250°
D. m∠1 + m∠6 = m∠7 + m∠4
Step-by-step explanation:
The given information are;
m∠7 = 55°
The angles formed by the transversal and the upper horizontal parallel line are (starting from the top left and moving in clockwise direction) = 1, 2, 4, 3
Similarly, the angles formed by the transversal and the lower horizontal parallel line are (starting from the top left and moving in clockwise direction) = 5, 6, 8, 7
Therefore, we have;
m∠7 ≅ m∠6 (Vertically opposite angles are congruent)
∴ m∠6 = m∠7 = 55°
m∠6 = 55° which corresponds with option A.
m∠5 + m∠6 = 180° (The sum of angles on a straight line)
∴ m∠5 = 180° - m∠6 = 180° - 55° = 125°
m∠5 = 125°
m∠1 ≅ m∠5 (Corresponding angles)
∴ m∠1 = m∠5 = 125°
m∠1 ≅ m∠4 (Vertically opposite angles)
∴ m∠1 = m∠4 = 125°
∴ m∠1 + m∠4 = 125° + 125° = 250°
m∠1 + m∠4 = 250° which corresponds with option C.
m∠1 ≅ m∠4 (Vertically opposite angles)
m∠6 ≅ m∠7 (Vertically opposite angles)
∴ m∠1 + m∠6 = m∠7 + m∠4 (Transitive property) which corresponds with option D.

Prove: (1+tanθ)/(1+cotθ )=secθ/cscθ
(1 + tanθ) / (1 + cotθ) = (1 + sinθ / cosθ) / (1 + cosθ / sinθ)
(1 + tanθ) / (1 + cotθ) = ((cosθ + sinθ) / cosθ) / ((sinθ + cosθ) / sinθ)
(1 + tanθ) / (1 + cotθ) = (1 / cosθ) / (1 / sinθ)
(1 + tanθ) / (1 + cotθ) = secθ / cscθ
