Answer: x=8
Step-by-step explanation: 8+14x+8x-4=180
The sum of a triangle will always be 180 degrees so you put 8+14x + 8x-4 equal to 180 and solve the equation, the answer is x=8

sandy found seashells and 119 starfish on the beach she gave 225 of the seashells to fred how many seashells does sandy niw have
Answers
Answer:
114?? Ummm I confused that's it......
After giving 225 of the seashells to Fred, then Sandy has -106 seashells now, which is determined by subtraction.
To calculate this, we subtract the number of seashells given to Fred from the initial number of seashells.
Seashells Sandy has now can be calculated as follows:
Seashells Sandy has now = Initial number of seashells - Seashells given to Fred
Therefore, we have:
= 119 - 225
Apply the subtraction operation to get
= -106
This negative sign indicates that there are not enough seashells
Therefore, after giving 225 of the seashells to Fred, then Sandy has -106 seashells now.

Answer:
y = -9 (negative 9)
Step-by-step explanation:
7 - 3(-9) =
7 - (-27) =
34
Hope this helped and pls mark brainliest!
Answer:
y = -9Explanation:
7 - 3y = 34
Simplify both sides of the equation
7 − 3y = 34
7 + −3y = 34
−3y + 7 = 34
Subtract 7 from both sides
−3y + 7 − 7 = 34 − 7
−3y = 27
Divide both sides by -3
−3y / -3 = 27 / -3
Simplify
y = -9

Our principal has to travel from one city to the next city at an average speed of 50km/hr. Compute for the distance between 2 cities
Answers
Answer:
The answer is false or "impossible"
Step-by-step explanation:
Heres why I say this:
If the “average speed” in one hour make the car travel 50km, it means the speed could not be constant. So, it could be 90km/h during the first 30 minutes and 10km/h during the second 30 minutes. If this is the case, for example, in the next 12 minutes after the first hour, the car could be traveled 18km at 90km/h, completing 50 + 18 = 68km. The tricky word “average” makes it impossible to answer. Good try, but no cigar.
Given f(x) = x + 1 and g(x) = 3x – 5,
what are
the restrictions on the domain when f(x)/g(x)
Answers
Answer:
There will be an asymptote at [tex]x=\frac{5}{3}[/tex], meaning the domain is restricted from (-∞, [tex]\frac{5}{3}[/tex])U([tex]\frac{5}{3}[/tex], ∞).
Step-by-step explanation:
When finding domain restrictions for an equation that has a fraction, take the denominator and set it equal to 0. Then, solve for x:
[tex]3x-5=0[/tex]
[tex]3x=5[/tex]
[tex]x=\frac{5}{3}[/tex]
Then we can determine that there's an asymptote at [tex]x=\frac{5}{3}[/tex] but that is the only restriction.
Complete the table using the equation y = 6x +3.
Answers
If x is 1, you’d have y = 6(1) + 3, so y = 9
If x is 2, you’d have y = 6(2) + 3, so y = 15
If they give you y and you need to solve for x, your equation can be changed to solve for x
y = 6x + 3
Subtract 3 from both sides
y-3 = 6x
Divide both sides by 6
x = (y - 3)/6
So if y is 21
x = (21-3)/6
x = (18)/6
x = 3

The two sides of the rectangle will be (x - 6) and (x - 2).
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
Sarah has a large square piece of foam for an art project.
The side lengths of the square are x in.
To fit her project, Sarah cuts a section of foam from two of the sies so now she has a rectangle.
The area of the rectangle given by the expression will be
⇒ x² - 8x + 12
Factorize the expression, then we have
⇒ x² - 6x - 2x + 12
⇒ x(x - 6) - 2(x - 6)
⇒ (x - 2)(x - 6)
Then the two sides of the rectangle will be (x - 6) and (x - 2).
