please help, i will give BRAINLIEST. Write an expression in the simplest form to model the perimeter of the following triangle:
Answers
Answer: Original expression: 2x - 11 + 4x + 7 + 3(x-4)
Simplified: 9x - 16
Step-by-step explanation:
2x - 11 + 4x + 7 + 3(x-4) becomes 2x - 11 + 4x + 7 + 3x -12
Group like terms, then combine to simplify:
2x + 4x + 3x -11 + 7 - 12
2x + 4x + 3x = 9x
-11 -12 + 7 = =23+7= -16
Simplified expression: 9x - 16

Step-by-step explanation:
Answer:
Number of trees used

Which of the followin statements are true about the equation 10x + 45x - 13 = 11(5x + 6) *
Answers
Step-by-step explanation:
The given expression is :
10x + 45x - 13 = 11(5x + 6)
We can simplify it as follows :
Opening parenthesis on RHS
10x + 45x - 13 = 55x + 66
Taking like terms together,
55x-55x = 13+66
0 = 13+66
The given expression has no solution, as the variable cancels out woh each other. It is a meaningless expression.

Y is directly related to X, and Y is 81 when X is 27.
The constant of variation is ___
(there are no answer choices, it's just a type in box so i need an exact answer please! :))
Answers
Answer:
Since x and y are directly related, the equation for their comparison will look like
kx = y
where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.
kx = y
k (27) = 81
k = 3
So, the constant of variation is 3.

A couch costs $350 to make. Before it is sold, it is marked up in price 80% more. How much will the couch cost?
Answers
Answer:$630
Step-by-step explanation:
What is 80% of 350?
Y is 80% of 350
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 80% * 350
Converting percent to decimal:
p = 80%/100 = 0.8
Y = 0.8 * 350
Y = 280
then u add 280 to 350

PLEASE HELP!!! A $950 computeris on sale for 15% off. If sales tax is 6% will this computer cost including tax?
Answers
Answer:
the computer will cost 864.5
Step-by-step explanation:
15% of 950 is 142.5.
950-142.5=807.5
6% of 950 is 57
Answer:
$855.95
Step-by-step explanation:
So We can first multiply the original price by 0.85 becuase its 15 percent off and we’re paying 85 percent of the original price basically.
You’ll get 807.50.
Now to find the sales tax we multiply that by 1.06 becuase the 100 percent is the price now and we’re just adding 6 percent so 1.06, and you’ll get 855.95
So no adding and subtracting and that takes off 2 steps and its way quicker
So the final answer is $855.95

O fx) = 2x + 3
O fx)= 4x +5
O fx) =3x-10
Answers
The function with the domain is given by f ( x ) = 2x + 3
What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as A
Now , the value of A is
Let the x values be x = { -7 , -1 , 3 , 4 , 7 )
Let the y values be y = { -11, 1 , 9 , 11 , 17 }
Now , the function is given as
f ( x ) = 2x + 3 be equation (1)
when x = -7
y = 2 ( -7 ) + 3
y = -11
when x = 7
y = 2 ( 7 ) + 3
y = 17
Hence , the function is f ( x ) = 2x + 3

Step-by-step explanation:
Given
[tex]Weights = \frac{3}{4}lb[/tex]
[tex]Bananas = 3[/tex]
Required
Determine the weight of each
To do this, we simply divide the total weight by the number of bananas.
[tex]Each\ Weight = \frac{3}{4}/3[/tex]
Convert to multiplication
[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]
[tex]Each\ Weight = \frac{1}{4}[/tex]
