Answer: x=-7
Step-by-step explanation:
1) The angles of a triangle are equal to 180
2) Add your angles together and set them equal to 180 like this:
x+59+x+51+84=180
3) Combine like terms:
2x+ 194 =180
4) Subtract 195 from both sides:
2x+ 194 =180
- 194 -194
2x = -14
5) Divide by 2 on both sides
2x= -14
/2 /2
x= -7

7y-9=3y+27 y= please help!
Answers
Answer:
Y=9
Step-by-step explanation:
Single out the variable, so subtract 3y from both sides.
7y-9-3y=3y+27-3y
4y-9=27
Then move the value to one side, so add 9 to both sides.
4y-9+9=27+9
4y=36
Then divide 36 by 4
4y/4=36/4
y=9

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = - ( 7v + 1.1 ) be equation (1)
Multiply by the value -1 throughout the brackets , we get
A = -1 ( 7v ) - ( 1.1 )
On simplifying , we get
A = -7v - 1.1
Hence , the expression is A = -7v - 1.1

We have ST=5x, TU=3x+32 and they're equal if T is the midpoint:
5x = 3x + 32
2x = 32
x = 16
ST = 5x = 80
So TU = 80 and SU=160

Tessa works for the park service in her town. She paid $21 for 3/4ton of wood chips to cover flower beds in the park. She want to know the cost of the wood chips on dollars per ton. What is the price per ton?
Answers
Answer:28
Step-by-step explanation:
The cost of the wood chips on dollars per ton is $28.
Given that, Tessa paid $21 for 3/4 ton of wood chips to cover flower beds in the park.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Let the cost of the wood chips on dollars per ton be x.
Now, the cost of the wood chips on dollars per ton = Cost of 3/4 ton of wood chips to cover flower beds in the park ÷ 3/4
x = 21 ÷ 3/4
= 21 × 4/3
= 28
Therefore, the cost of the wood chips on dollars per ton is $28.

Write the domain and the range of the function as an inequality, using set notations, and using interval notation. Also describe the end behavior of the function or explain why there is no end behavior (19 points and brainliest)
Answers
Answer:
Step-by-step explanation:
I think we need to define domain and range first.
Domain is the set of all x values where the function f(x) exists or is defined.
Range is the set of all y values that will result from substituting all x values (the domain) into the function.
So for g(x) = 2x - 2 we can evaluate g(x) at any point, and we will get a real answer for y.
So the range of g(x) = 2x -2 is also all real numbers, because no matter what value of x is, we can always multiply that number by 2 and subtract 2.
The inequality does not affect the domain and range of linear functions at all. Don't confuse domain and range with a solution to an inequality. These two concepts are different. Domain and range mean all possible values of x and y that could be substituted into the inequality. A solution means all possible values that make the inequality statement true.
The domain as an inequality would be -∞ < x < ∞
The range as an inequality would be -∞ < y < ∞
As a set notation:
Domain {x | -∞ < x < ∞}
Range {y | -∞ < x < ∞}
In interval notation:
Domain (-∞ , ∞)
Range (-∞ , ∞)
End behavior:
As x gets larger and larger, g(x) gets larger and larger as well, and as x gets smaller, g(x) gets smaller too.
