In a triangle the longest side is 3 inches longer than twice the shortest side. The third side is 2 inches less than twice the shortest side. If the perimeter of the triangle is 61 inches, which equation should be used to find the length of the shortest side, s?
Answers
Answer:
your face
Step-by-step explanation:
:)
Let's let A, B, C represent the sides of the triangle from shortest to longest, then:
A = ?
B = A + 2
C = A + 3
To find the perimeter we add all the sides p = A + B + C, and based on the problem
p = A + B + C
26 = A + (A + 2) + (A+3)
26 = 3A + 5
21 = 3A
7 = A
Now we can use the fact that A = 7 in, which is the shortest side, to find all three sides:
A = 7
B = 7 + 2 = 9
C = 7 + 3 = 10
The lengths of the sides are 7 in, 9 in, and 10 in.

Solve for x:
6x + 9 = 4x + 25
Answers
Answer:
x = 8
Step-by-step explanation:
Solve for x:
6 x + 9 = 4 x + 25
Subtract 4 x from both sides:
(6 x - 4 x) + 9 = (4 x - 4 x) + 25
6 x - 4 x = 2 x:
2 x + 9 = (4 x - 4 x) + 25
4 x - 4 x = 0:
2 x + 9 = 25
Subtract 9 from both sides:
2 x + (9 - 9) = 25 - 9
9 - 9 = 0:
2 x = 25 - 9
25 - 9 = 16:
2 x = 16
Divide both sides of 2 x = 16 by 2:
(2 x)/2 = 16/2
2/2 = 1:
x = 16/2
The gcd of 16 and 2 is 2, so 16/2 = (2×8)/(2×1) = 2/2×8 = 8:

Maya painted 3/4 of her art project in the morning and 1/8 of her project in the evening which equation can Maya use c to find how much of the project she painted
Answers
The equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]
Let the size of the art be x.
In the morning, she paints 3/4 of x.
So, we have:
[tex]\mathbf{Morning = \frac 34 x}[/tex]
In the evening, she paints 1/8 of x.
So, we have:
[tex]\mathbf{Evening = \frac 18 x}[/tex]
So, the amount of project painted is:
[tex]\mathbf{c = Morning + Evening}[/tex]
This gives
[tex]\mathbf{c = \frac 34x + \frac 18x}[/tex]
Take LCM
[tex]\mathbf{c = \frac{6x + x}8}[/tex]
Add the numerator
[tex]\mathbf{c = \frac{7x}8}[/tex]
So, we have:
[tex]\mathbf{c = \frac{7}{8}x}[/tex]
Hence, the equation to find the proportion painted is: [tex]\mathbf{c = \frac{7}{8}x}[/tex]

Column 2 is labeled height (inches) with entries 3.75, 4.1, 4.45, 4.8. Arrows are drawn from each row to the next. Use the table to interpret the rate of change.
What is the change for each consecutive input?
What is the change for each consecutive output?
What is the rate of change for the relationship?
Answers
Answer:1. 0.35. 0.35
Step-by-step explanation:
I did the question on edgenuity
The change for each consecutive time given is: 1
The change of each consecutive height given is: 0.35
The rate of change for the relationship between time and height is: 0.35
The table that displays the height of water when a pool is being filled against time is shown in the image attached. (See attachment).
Recall:
Rate of change can be calculated as: change in output / change in input
Change in output = difference between consecutive outputs
Change in input = difference between consecutive inputs
In the question given,
Time is input
Height is output
Thus:
Change for each consecutive input (time):
13 - 12 = 12 - 11 = 11 - 10 = 1Therefore, the change of each consecutive input (time) is: 1
Change for each consecutive output (height):
4.8 - 4.45 = 4.45 - 4.1 = 4.1 - 3.75 = 0.35Therefore, the change of each consecutive output(height) is: 0.35
Rate of change of the relationship between time and height:
Rate of change = change in height / change in time
Rate of change = 0.35/1 = 0.35
In summary:
The change for each consecutive time given is: 1
The change of each consecutive height given is: 0.35
The rate of change for the relationship between time and height is: 0.35

Answer:
I think the answer would be the fourth answer or the second answer.
sorry if its not the correct answer.
Step-by-step explanation:
D; 10.5x + 45 < 12.5x + 35
We are told that;
Charges of Company A; $10.50 for each t-shirt plus one-time design fee of $45. If x is the minimum number of shirts ordered so that the charge at Company A is less than the total charge at Company B. Thus;C_a = 10.5x + 45
Similarly, we are told that;
Charges of Company B; $12.50 for each t-shirt plus one-time design fee of $35. If x is the minimum number of shirts ordered so that the charge at Company A is less than the total charge at Company B. Thus;C_b = 12.5x + 35
Since we want to make C_a < c_b
Then, we will have;
10.5x + 45 < 12.5x + 35

Which of the following equations has a graph with a y-intercept of -8?
Ay=3x - 8
B. y = -8x + 3
C. 3x - 8y = -5
D. -8x + 3y = -5
Answers
The equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8
To determine which of the given equations has a graph with a y-intercept of -8.
We will compare the equations with the slope-intercept form of the equation of a straight line.
The slope-intercept form of the equation of a straight line is
y = mx + c
Where m is the gradient or slope
and c is the y-intercept
For A. y =3x - 8By comparing with y = mx + c
m = 3 and c = -8
∴ The y-intercept here is -8
For B. y = -8x + 3By comparing with y = mx + c
m = -8 and c = 3
∴ The y-intercept here is 3
For C. 3x - 8y = -5This can be written as
y = (3/8)x + 5/8
By comparing with y = mx + c
m = 3/8 and c = 5/8
∴ The y-intercept here is 5/8
D. -8x + 3y = -5This can be written as
y = (8/3)x - 5/3
By comparing with y = mx + c
m = 8/3 and c = - 5/3
∴ The y-intercept here is -5/3
Hence, the equation that has a graph with a y-intercept of -8 is y =3x - 8. The correct option is A. y =3x - 8

Estimate the value of negative square root of 150.
Answers
Answer:
-12.25
Step-by-step explanation:
Let's investigate what happens when negative values appear under the radical symbol (as the radicand) for cube roots and square roots.
In some situations, negative numbers under a radical symbol are OK. For example, radnegnew14is not a problem since (-2) • (-2) • (-2) = -8, making the answer -2. In cube root problems, it is possible to multiply a negative value times itself three times and get a negative answer.
Difficulties, however, develop when we look at a problem such as radnegnew214. This square root problem is asking for a number multiplied times itself that will give a product (answer) of -16. There simply is no way to multiply a number times itself and get a negative result. Consider: (4) • (4) = 16 and (-4) • (-4) = 16.
CUBE ROOTS:
radnn1
BUT
SQUARE ROOTS:

Yes, (-2) x (-2) x (-2) = -8.
No problem.
Nope! (4) x (4) ≠ -16.
Nope! (-4) x (-4) ≠ -16.
bullet Square roots are the culprits! The difficulties arise when you encounter a negative value under a square root. It is not possible to square a value (multiply it times itself) and arrive at a negative value. So, what do we do?
statement
The square root of a negative number does not exist among the set of Real Numbers.
When problems with negatives under a square root first appeared, mathematicians thought that a solution did not exist. They saw equations such as x2 + 1 = 0, and wondered what the solution n3 really meant.
In an effort to address this problem, mathematicians "created" a new number, i, which was referred to as an "imaginary number", since it was not in the set of "Real Numbers". This new number was viewed with much skepticism. The imaginary number first appeared in print in the year 1545.
def The imaginary number "i" is the square root of negative one.
neg i
An imaginary number possesses the unique property that when squared, the result is negative.
irad1
Consider: irad2a
The process of simplifying a radical containing a negative factor is the same as normal radical simplification. The only difference is that the irad4 will be replaced with an "i ".
As research with imaginary numbers continued, it was discovered that they actually filled a gap in mathematics and served a useful purpose. Imaginary numbers are essential to the study of sciences such as electricity, quantum mechanics, vibration analysis, and cartography.
When the imaginary i was combined with the set of Real Numbers, the all encompassing set of Complex Numbers was formed.

what is y 5(y -10)=-5
Answers
Answer:
y=9
Step-by-step explanation:
5(y-10)=-5
We move all terms to the left:
5(y-10)-(-5)=0
We add all the numbers together, and all the variables
5(y-10)+5=0
We multiply parentheses
5y-50+5=0
We add all the numbers together, and all the variables
5y-45=0
We move all terms containing y to the left, all other terms to the right
5y=45
y=45/5
y=9
The value of y = 9 is correct. Therefore, the solution is y = 9.
To solve the equation 5(y - 10) = -5 for y, follow these steps:
Step 1: Distribute the 5 on the left side of the equation:
5y - 50 = -5
Step 2: Move the constant term to one side by adding 50 to both sides:
5y - 50 + 50 = -5 + 50
Step 3: Simplify the left side and evaluate the right side:
5y = 45
Step 4: Isolate y by dividing both sides by 5:
5y / 5 = 45 / 5
Step 5: Simplify and calculate y:
y = 9
The solution to the equation is y = 9. To verify, substitute y with 9 in the original equation:
5(9 - 10) = -5
5(-1) = -5
-5 = -5
Since both sides are equal, the value of y = 9 is correct. Therefore, the solution is y = 9.
