Answer:
First side=7
Second side =28
Third side =8
explanation:
Perimeter of a triangle is the sum of the length of the sides of the triangle. Given that the perimeter of the triangle = 43 inches
Second side is 4 times the first side
Third side is 1 inch longer the first
Let's call the first side x
Then equation for the perimeter of the triangle is given by
x+4x+x+1=43
We solve for x
6x+1=43
6x=43-1
6x=42
x=42/6
x=7
Therefore the first side x=7, the second side is 4x= 4*7=28, third side= 1+x= 1+7=8

A system of linear equations includes the line that is created by the equation y = 0.5 x minus 1 and the line through the points (3, 1) and (–5, –7), shown below. What is the solution to the system of equations?
Answer:
The solution to the system of equations is x = 4 and y = 2.
Step-by-step explanation:
From statement we know that the first line is [tex]y = 0.5\cdot x[/tex]. The second line is determined by knowing two distinct points and solving the resulting system of equations by definition of the equation of the line:
[tex](x_{1},y_{1}) = (3,1)[/tex] and [tex](x_{2}, y_{2}) =(-5,-7)[/tex]
[tex]3\cdot m + b = 1[/tex] (1)
[tex]-5\cdot m + b = -7[/tex] (2)
The solution of the system of equations is:
[tex]m = 1[/tex], [tex]b = -2[/tex]
The second line is represented by [tex]y = x-2[/tex]. And the resulting system of equations is:
[tex]0.5\cdot x -y = 0[/tex] (3)
[tex]x-y = 2[/tex] (4)
The soltuion to the system of equations is:
[tex]x = 4[/tex], [tex]y = 2[/tex]
The solution to the system of equations is x = 4 and y = 2.

From: Mr. Otero
tell whether the given statement below illustrate quadratic inequality in one variable or not you may translate into mathematical symbols to justify your answers.
Answer:
Step-by-step explanation:
Let width of the parking space = x meters
Since, parking space is 6 meters longer than the width,
Length of the parking space = (x + 6) meters
Area of the parking space = Length × Width
= x(x + 6)
Area of the parking space is less than 40 square meters.
Therefore, inequality representing the area of the parking will be,
x(x + 6) < 40
x² + 6x < 40
x² + 6x - 40 < 0
x² + 10x - 4x - 40 < 0
x(x + 10) - 4(x + 10) < 0
(x - 4)(x + 10) < 0
-10 < x < 4
For -10 < x ≤ 0, width of the paring will be negative.
Therefore, possible values of x will be in the interval,
0 < x < 4
Or 0 < width < 4
Length of the parking space will be,
6 < Length < 10

Use the percent error formula:
% error = | (approx - exact) ÷ approx | x 100
Plug in the approx. and exact values:
| (8.9 - 8.7) ÷ 8.9 | x 100

i don’t know how to find the equation for this problem
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance. The dance will cost $400.
Write an inequality to determine the number, ttt, of tickets the committee could sell to have money left over after they pay for this year's dance.
Answer:
t > 82
Step-by-step explanation:
First write what we know.
Earned $72
$4 per ticket, t
Cost is $400
So let's write our equation:
The cost is $400 so we put that on the left side,
$400 =
Now on the right side, we know they earned $72, so +$72 and each ticket (t) is $4 so $4t would represent the amount earned after they sell a certain number of tickets.
So we write:
$400 = $4t + $72 Now solve for t to find the number of tickets they need to sell.
400 = 4t + 72 Subtract 72 from each side.
400 - 72 = 4t + 72 - 72
328 = 4t Divide each side by 4.
328/4 = 4t/4
328/4 = t
82 = t
If the committee wants money left over they need to sell more than 82 tickets!
Our inequality is:
t > 82

Answer:
Angle F is 50° because their side lengths are different but the angle measurements did not change. All triangles add up to 180 degrees and a right angle is 90 and it gives you the other angle measurement. So you would do 40 plus 90 which would get you 130. To find the last angle you would do 180 minus 130 which is 50. Angle F is 50 degrees.

The required equation of the lines are y = 5/3x , y = -3/4x and y = -4x which passes through y axis and points (-3, -5) , (-4, 3) and (1, -4) respectively.
Given that,
To plot four lines. Each line should pass through the point on the y-axis and one of the other four points.
A line can be defined by the shortest distance between two points is called a line. The standard equation of the line is y = mx +c where c = intercept and m, = slope of the equation.
Here, (-3, -5) , (-4, 3) and (1, -4)
Three lines are to be plotted on the curve which passes through (-3, -5) , (-4, 3), and (1, -4) and at any point on the y-axis,
So the equation are,
y = 5/3x passes through (-3, -5 ) and 0 on y axis
y = -3/4x passes through (-4, 3) and 0 on y axis
y = -4x passes through (1, -4 ) and 0 on y axis
Thus, the required equation of the lines are y = 5/3x , y = -3/4x and y = -4x which passes through y axis and points (-3, -5) , (-4, 3) and (1, -4) respectively.
