Answer:
x=16
Step-by-step explanation:
First, minus 80 from 180 because the sum of all the angles in a triangle is 180. Then use linear equations. 100=(4x-4)+(0.5x+32)
After that, you will get 100=4.5x+28
x=16

The Lanier band is raising money for their annual trip. They are selling insulated cups for $25 each and have already made $1500. They need to make at least $10,000 to go on the trip. Determine the smallest number of cups they need to sell.
Answers
Answer:
The probably need to sell 340 more
Step-by-step explanation:
1500divided by25 is 60. So they have sold 60. 10,000 divided by 25 is 400, so they need to sell 400 cups to reach their goal.
During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibels?
Answers
Hey Child.
The answer to this is 1 or 7:
To find the range for the number of measures played to satisfy our solution, we must solve for x using s = 80.
Next, we subtract 50 from both sides of the equation.
Next, we divide both sides of the equation by 10
Next, to eliminate the absolute value bars, we will add a ± sign in front of our s value, 3.
Finally, we add 4 to both sides of our equation giving us 4 ± 3 = x
Separating this into two equations, we get 4 - 3 = x and 4 + 3 = x
Therefore, x, the number of measures of music played, must be either 1 or 7.

It will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.
Given that,
A sprout in Jessie’s garden is 5 1/5 cm tall and is growing 1 3/10 cm each week. Write and solve equality in order to resolve how many weeks it will take for the plant to be 13 cm tall is to be determined.
In calculation, it deals with number of procedures according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
Let the number of weeks be x, the height after each week be y
According to the question,
y = 5 1 /5 + 1 3/10 x
y = 26 / 5 + 13 / 10x
Now,
y = 13
13 = 26 / 5 + 13 /10x
13/10x = 13 - 26 / 5
x = 39 × 10 / 5 × 13
x = 3 ×2
x = 6
Thus, it will take 6 weeks for the sprout in Jessi's garden to grow 13 cm tall.

What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is the function -
f(x) = 3 - x/7
The given function is -
f(x) = 3 - x/7
we can write -
y = 3 - x/7
Replace [y] and [x], as follows -
x = 3 - y/7
y/7 = 3 - x
y = 7(3 - x)
f ⁻¹(x) = 7(3 - x)
Therefore, the inverse of the function f(x) is equivalent to -
f ⁻¹(x) = 7(3 - x).
