(3x-5) + (x+1) = 180
The value of 'x' for the given expression is calculated as (x = 48).
What is defined as the linear equation in one variable?A linear equation in one variable is an equation that has only one solution.
It is expressed in the form ax+b = 0, where a and b are two integers and x is a variable. The numbers a' and b' are real numbers.'a' and 'b' are both greater than zero.2x+3=8, for example, is a linear equation with a single variable.Now, for the given expression;
(3x-5) + (x+1) = 180
Open the brackets.
3x-5 + x+1 = 180
Add the similar parts;
4x - 4 = 180
Further simplifying;
4x = 180 + 4
4x = 184
x = 184/4
x = 48
Therefore, the value of 'x' is estimated as 48.

Bill's school is selling tickets to a fall musical.
On the first day of ticket sales the school sold 1 adult ticket
and 6 child tickets for a total of $52.
The school took in $66 on the second day by selling 1 adult
ticket and 8 child tickets.
Find the price of an adult ticket.
•$3
•$10
•$7
•$9
By solving a system of equations, we can see that the adult ticket costs $10.
How to find the price of the adult ticket?
Let's define the two variables:
x = price of the adult ticket.y = price of the child ticket.With the given information, we can write a system of equations:
1*x + 6*y = $52
1*x + 8*y = $66
By taking the difference between the two equations we get:
(1*x + 8*y) - (1*x + 6*y) = $66 - $52
2y = $14
y = $14/2 = $7
Now that we know the value of y, we can find the value of x.
Replacing the value of y in the first equation we get:
1*x + 6*$7 = $52
x = $52 - 6*$7 = $10
With this, we know that the adult ticket costs $10.

the inequality always, sometimes, or never true
4x8> 1 + 4(x + 3)
The given inequality is never true which means it has no solutions. If an inequality has no actual solution, then there aren't any numbers that might be used to solve it and make the statement true. An inequality can be made true by substituting any real number into it if the solution to the inequality is all real numbers.
Given the expression is 4x ₋ 8 > 1 ₊ 4(x₊3)
first apply the distributive property.
4x ₋ 8 > 1 ₊ 4x ₊ 12
now combine the like terms.
4x ₋ 8 > 4x ₊ 13
Variables should be moved to the equation's left side.
4x ₋ 4x > 13 ₊ 8
combine like terms.
0 > 13 ₊ 8
calculate the sum.
0>21
This is the solution of inequality which has no solutions.
Hence the inequality of the expression is never true.

I started golfing again recently and I've played 5 rounds of golf with the following scores: 92, 88, 85, 90, and 89. What score would I need the next time I play to have an average below 88.
The next score should by less than 84 to have an average below 88.
What is an average?The term average is the sum of all the numbers divided by the total number of values in the set.
Mathematically,
Average = Sum of the observations/number of observations
Now given that,
Scores = 92, 88, 85, 90, and 89
Rounds = 5
Let x be the score the score for next round or sixth round.
So, According to question,
Average < 88
So, Average = Sum of the scores/number of rounds
⇒ Average = (92 + 88 + 85 + 90 + 89 + x)/6
⇒ Average = (444 + x)/6
⇒ (444 + x)/6 < 88
⇒ (444 + x) < 528
⇒ x < 528 - 444
⇒ x < 84
Thus, the next score should by less than 84 to have an average below 88.

Patricia wishes to have a rectangular garden in her backyard. She has 88 ft of fencing with which to enclose her garden. Letting x denote the width of the garden, find a function f in the variable x giving the area of the garden.
The area of the rectangular garden in terms of a function in x is given by 44x - x²sq. ft.
What is the area of a rectangle?
A rectangle is a closed geometric figure with opposite sides equal to each other. The area of this rectangle is given by the product of its length and width.
Calculating the area of a rectangular garden in terms of a function in x
Let us consider a variable x that denotes the length of a rectangular garden
Given perimeter of a rectangular garden is 88 ft with y as the width of a rectangular garden
Perimeter = 2×(length + breadth)
88 = 2(x + y)
44 = x + y
y = 44 - x
Area of a rectangular garden = xy
= x(44 - x)
= 44x - x² sq. ft
Hence, the area of a rectangular garden in terms of a function in x is given by 44x - x² sq. ft.

y= 1/16 is the solution of the equation where y is [tex]e^{-2ln4}[/tex]
The expression is given to be [tex]e^{-2ln4}[/tex]
The formula is given to be [tex]e^{lnx} =x\\[/tex]
also it is given that ln[tex]e^{x}[/tex]=x
Now to find and evaluate [tex]e^{-2ln4}[/tex]
let y=[tex]e^{-2ln4}[/tex]
taking ln both sides,
ln y = ln[tex]e^{-2ln4}[/tex]
ln y= -2 ln4
ln y= ln 4^-2

y = 4^-2
y=1/16
Thus , y= 1/16 is the solution of the equation

Landon was making snacks for his family for the week. He used 25/35 of a pound of peanuts. Additionally he use 1/7 of a pound of almonds. At the end of the week, he determined that 3/5 of the snacks were leftover. At the end of the week, how much snacks, in pounds, was used?
Landon used an amount of 4 / 7 of a pound of snacks for his family of the week.
How to estimate the amount of snacks spent per week
In this problem we must determine the total amount of snacks used by Landon in a period of a week, which is found by the summing fractions. Then, we must solve the following linear equation:
(3 / 5) · x = x - 25 / 35 - 1 / 7
(3 / 5) · x = x - 25 / 35 - 5 / 35
(3 / 5) · x = x - 20 / 35
x - (3 / 5) · x = 20 / 35
(2 / 5) · x = 20 / 35
7 · x = 10
x = 10 / 7
And the amount of snack used is determined by the following subtraction:
z = (2 / 5) · (10 / 7)
z = 20 /35
z = 4 / 7
Landon used an amount of 4 / 7 of a pound of snacks for his family of the week.

In the Student Shoppe, Jackie spent $1 less than twice what Gail spent. If together they spent $11, find the amount of money Gail spent.
Answer:
Gail spent $4 and Jackie spent $7
Step-by-step explanation:
Let j = Jackie
Let g - Gail
j = 2g -1 j + g = 11
substitute 2g - 1 for j in the second equation
j + g = 11
2g - 1 +g =11 Combine the g's
3g -1 = 11 Add 1 to both sides of the equation
3g = 12 Divide both sides by 3
g = 4
Plug 4 in for g to find j
j = 2g -1
j = 2(4) -1
j = 8 -1
j = 7
