side one is 5 side two is 10 and the third side is 13. 28 is not divisible by three so if one side i 5 ft longer and another side is 8 ft longer then you add them 5+8=13 then subtract 13 from the perimeter 28-13=15 then divide 15 by 3 and get 5 5 5. add 5 (5+5) (5+8).
The lengths of the sides of the triangle are 5 feet, 10 feet, and 13 feet.
Let's assume the second side of the triangle has a length of x feet.
According to the given information, the first side of the triangle is 5 feet longer than the second side, so its length would be x + 5 feet.
Similarly, the third side is 8 feet longer than the second side, so its length would be x + 8 feet.
The perimeter of a triangle is calculated by adding the lengths of all three sides, so we can write the equation:
x + (x + 5) + (x + 8) = 28
Now let's solve this equation to find the value of x:
3x + 13 = 28
3x = 28 - 13
3x = 15
x = 15 / 3
x = 5
So, the second side of the triangle has a length of 5 feet.
Using this value, we can find the lengths of the other two sides:
First side: x + 5 = 5 + 5 = 10 feet
Third side: x + 8 = 5 + 8 = 13 feet
Therefore, the lengths of the sides of the triangle are 5 feet, 10 feet, and 13 feet.

If a and −a are numbers on the number line, which expression MUST give the distance between them?
Answer:
|2a|
Step-by-step explanation:
Note that distance is positive. a less -a comes out to +2a, which is the distance between and -a.
Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 < x < 4.5}
Answer:
{x | x = 0.5 or x = 4.5}
Explanation:
Before we begin, remember that:
The modulus gives the positive value of what's inside it.
This means that:
|a| = |-a| = a
Now, for the given, we have:
|2x-5| = 4
From the above rule, we can deduce that:
either:
2x - 5 = 4
2x = 4 + 5 = 9
x = 4.5 ............> first solution
Or:
2x - 5 = -4
2x = 5-4 = 1
x = 0.5 ..........> second solution
Now, we check:
at x = 4.5: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified
at x = 0.5: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified
Hope this helps :)
Answer:
{x | x = 0.5 or x = 4.5}

Write an expression that shows how to use the halving and doubling strategy to find 28x50
Write an expression that shows how to use the halving and doubling strategy to find 28x50
Halving strategy means we divide by 2
Doubling strategy means we multiply by 2
We apply halving strategy for 28 and doubling strategy for 50
Half of 28 is 14
Double of 50 is 100
So 14 * 100 = 1400
Now we check with 28 * 50
28 x 50 = 1400
So required expression is

c=
3.2c+1.7=24.1
First subtract 1.7 from both sides
3.2c=22.4
Now divide both sides by 3.2
c=7
Now put it in the equation.
3.2(7)+1.7=24.1

evaluate 4 to the power of 3 . (100/25) - 5 to the power of 0
Hey there!!
Remember :-
=> Anything to the power 0, is always one.
In the question, is states at the last that the final answer is powered with zero.
Hence, the required answer is "1".
Hope my answer helps!!
Find the equation of the line that passes through the points (2, 8) and (-2, 6).
(multiple choice)
A. y = -1/2 x + 9
B. y = -2x + 12
C. y = 1/2 x + 7
D. y = 2x + 4
The correct answer is C. y = 1/2x + 7
In order to find this, we first have to look for the slope. We can do that by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (8 - 6)/(2 - -2)
m = 2/4
m = 1/2
Now we can solve using the slope intercept form and a given point.
y = mx + b
8 = 1/2(2) + b
8 = 1 + b
7 = b
Now we can put these into the equation and model as y = 1/2x + 7

The answer x = 11 is correct for problem 4. Nice work.
Use this x value to find the answer in problem 5. From problem 4, we're told that Romeo runs at a speed of 5 m/s. If he runs for x = 11 seconds,then he runs a total distance of:
5*x =(5 m/s)*(x meters) = (5 m/s)*(11 seconds) = 5*11 = 55 meters
The answer to problem five is 55 meters
A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday. There were 57 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on thursday
Answer:
325 hamburgers were sold on Thursday.
Step-by-step explanation:
Let h be the number of hamburgers and c be the number of cheeseburgers.
Using this information we can set up two equation as:
[tex]h+c=593\\c=h-57[/tex]
Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:
[tex]h+h-57=593\\2h-57=593\\2h=650\\h=325[/tex]
Therefore, the number of hamburgers sold on Thursday were 325.

If the measure of angle ABF=6x+26 and the measure of angle EBF=2x9 and measure of angle ABE= 11x-31 find the measure of angle ABF
Its not clearly given that whether EBF = 2x + 9 or 2x - 9.
I have written the solution for both.
If EBF = 2x + 9,
then ABF = 6x + 26 and ABE = 11x - 31.
Now, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x + 9)
= (6x + 2x) + (26 + 9)
= 8x + 35
11x - 8x = 35 + 31
3x = 66
x = 22
Therefore, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°
If EBF = 2x - 9,
then ABF = 6x + 26 and ABE = 11x - 31.
Now, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x - 9)
= (6x + 2x) + (26 - 9)
= 8x + 17
11x - 8x = 17 + 31
3x = 48
x = 16
Therefore, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°
The expression for angle ABF: ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°
What is the angleFrom the question: If EBF = 2x + 9, then ABF = 6x + 26 and ABE = 11x - 31.
When, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x + 9)
= (6x + 2x) + (26 + 9)
= 8x + 35
11x - 8x = 35 + 31
3x = 66
x = 22
Hence, ABF = 6x + 26 = 6(22) + 26 = 132 + 26 = 158°
When EBF = 2x - 9,
So, ABF = 6x + 26 and ABE = 11x - 31.
When, ABE = ABF + EBF
11x - 31 = (6x + 26) + (2x - 9)
= (6x + 2x) + (26 - 9)
= 8x + 17
11x - 8x = 17 + 31
3x = 48
x = 16
So, ABF = 6x + 26 = 6(16) + 26 = 96 + 26 = 122°

which shows the image of quadrilateral ABCD after transformation
need the image to see the answer
which rule describes the composition of transformations that maps pre- image ABCD to final image A’’B’’C’’D’’ ?
In order to identify the transformations from ABCD to A''B''C''D'', carefully analyze changes in position and orientation. If, for instance, you observe a translation to the right by 3 units followed by a clockwise rotation of 90 degrees about point P, the rule in symbolic notation would be: T(3, 0) • R(P, 90)(x, y)
Identify the individual transformations:
Examine the image carefully and determine what transformations are involved in mapping ABCD to A''B''C''D''. Common transformations include translations (shifting), reflections (flipping), and rotations (turning).
Look for clues like changes in position, orientation, or direction to identify the transformations.
Analyze the order of transformations:
Determine the sequence in which the transformations were applied. This is crucial because the order affects the final result.
Look for intermediate images (like A'B'C'D' in your case) that show the effects of individual transformations.
Write the rule in symbolic notation:
Once you've identified the transformations and their order, use appropriate notation to express the composition rule.
Common notations include:
T(a, b) for translation by (a, b) units.
R(O, θ) for rotation about point O by θ degrees.
r(line) for reflection over a line.
Combine the notations for individual transformations using the composition symbol "•" to represent their sequential application.
If you determine that the transformations are a translation by (-6, 1) units followed by a reflection over the x-axis, the rule would be written as:
r(x-axis) • T(-6, 1)(x, y)
Complete question:
Which rule describes the composition of transformations that maps pre- image ABCD to final image A’’B’’C’’D’’ ?
Final answer:
The question seeks a description of the composition of geometric transformations mapping a pre-image to a final image, involving transformations such as translations, rotations, reflections, and dilations.
Explanation:
The question revolves around the concept of geometric transformations, specifically the composition of transformations as they apply to mapping a pre-image (ABCD) to a final image (A''B''C''D''). The composition of transformations includes operations such as translations, rotations, reflections, and dilations. To provide an accurate description of the rule that maps the pre-image to the final image, we would need to know the specific transformations applied in sequence. For instance, if ABCD was translated right by 5 units and then rotated about the origin by 90 degrees, the compositional rule would be a translation followed by a rotation.
