Answer:
r=1
Step-by-step explanation:
3+2r=5
-3 -3
2r=2
r=1
Answer: R equals 1. Move the constant to the right and change it's sign. Subtract the numbers. Divide both sides of the equation by 2. So that leaves you with 1.

Write a function inches_to_ft that takes a number of inches x and returns the number of feet. One foot equals 12 inches.
Answer:
def inch_to_feet (x):
return 1/x
Step-by-step explanation:
Implementating the program Using python 3 :
def - - - > function declaration keyword
inch_to_feet - - > function name
x - - > argument which the function takes
The value returned is a conversion of x which is in inches to feets
1/12 feet = 1 inch
To see the value returned ;
We can run the code :
def inch_to_feet(x):
return (1/12)*x
b = inch_to_feet(12)
print(b)
The code above will print 1.

An auditorium is designed in such a manner that an additional seat is added to each row. If the theater has 46 rows and the last row contains 56 seats, then how many people could be seated in the auditorium?
Answer:
Step-by-step explanation:
Given that they give us how many seats are in the last row we know that each row contains 56 seats and we have 46 rows. If you multiply 56 by 46 you get 2,576. If a seat is added to each row there are 46 seats you must add to 2,576. This will make your answer 2,622

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
Answer:
A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.
Step-by-step explanation:
To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

Answer:
Step-by-step explanation:
If may buys an item that, after 10% sale, costs 18 dollars
let x be original price

on 20 of 22 Which equation describes the line with slope 8 that contains the point (-3, -6)? O A. y + 3 = 8(x+6) O B. y-3 = 8(x-6) c. y - 6 = 8(x-3) O D. y + 6 = 8(x + 3)¹
Answer:
Hi, I just wanted to say that I got this question a few days ago on my test!
I haven't gotten my grade yet and I dont know if I got it right but I hope you figure it out! Best of luck to you!
The equation of a line in point slope form is :
Y - y1 = m(x -x1)
M is the slope given as 8
Y1 and x1 are the x and y values of the given point:
Y - (-6) = 8(x - (-3))
Rewrite as:
Y + 6 = 8(x + 3)

Two triangles are similar. The smaller triangle has side lengths 10, 20, and 15 units. The larger triangle's longest side is 52 units. What is the perimeter of the larger triangle? first o answer get brainliest
Answer:
117
Step-by-step explanation:
So basically, how I figured it out is 20-15 is 1/4 of 20. So I had to find the 1/4 of 52 which is 13. But 15 is 3/4 of 20 so then you multiply 13 times 3 which is 39.
10 is half of 20. So you find half of 52. Which is 26.
52+39+26 is your equation.
Which adds up to 117. So 117 is your answer
I used 20 because in the smaller triangle 20 was the largest side like 52 in the biggest triangle.
Brainliest would be appreciated

[tex]1\cdot \text{foot} = 12\cdot \text{inches} \implies 5 \cdot\text{foot} =5\cdot 12 \cdot\text{inches} \implies 5 \cdot\text{foot} =60 \cdot\text{inches}[/tex]
tanner had $32.80 and spent 15% of his money on a book including tax. If he paid with a $5 bill, how much change did tanner get back?
Answer:
$0.08
Step-by-step explanation:
Find the cost of the book, by finding 15% of 32.80
32.80(0.15)
= 4.92
To find how much change he got back, subtract this from 5:
5 - 4.92
= 0.08
So, he got $0.08 back in change
Answer:
actually he got 23 cents back

The length of the longer leg of a right triangle is 4ft more than twice the length of the shorter leg. The length of the hypotenuse is 6ft more than twice the length of the shorter leg. Find the side lengths of the triangle.
a. Find the length of the shorter side
b. Find the length of the longer side
c. Find the length of the hypotenuse
d. Find the side lengths of the triangle.
Answer: Shorter side = 10 feet
Longer side = 24 feet
Hypotenuse = 26 feet
The side lengths of the triangle are 10ft, 24ft and 26ft.
Step-by-step explanation:
Let the length of the shorter leg be x.
The length of the longer leg of a right triangle is 4ft more than twice the length of the shorter leg. This will be: = 2x + 4
The length of the hypotenuse is 6ft more than twice the length of the shorter leg. This will be: = 2x + 6
Note that the square of the hypothenuse will be equal to the square of the other two sides. This will be:
x² + (2x + 4)² = (2x + 6)²
x² + (2x + 4)(2x + 4) = (2x + 6)(2x + 6)
x² + 4x² + 8x + 8x + 16 = 4x² + 12x + 12x + 36
x² + 4x² + 16x + 16 = 4x² + 24x + 36
5x² + 16x + 16 = 4x² + 24x + 36
Collect like terms
5x² - 4x² + 16x - 24x + 16 - 36 = 0
x² - 8x - 20 = 0
x² - 10x + 2x - 20 = 0
x(x - 10) + 2(x - 10) = 0
Therefore, x - 10 = 0
x = 10
a. length of the shorter side = 10ft
b. Length of the longer side = 2x + 4 = 2(10) + 4 = 20 + 4 = 24ft
c. length of the hypotenuse = 2x + 6 = 2(10) + 6 = 20 + 6 = 26ft
d. The side lengths of the triangle are 10ft, 24ft and 26ft.

2. in a class of 50 students, the number of females is 2 more than 5 times the number of males. How many males and females are there in the class?
Answer:
The number of male students is 8, while the number of female students is 42.
Step-by-step explanation:
To determine the number of male and female students in the class, knowing that in total there are 50 students, and that the number of female students is two more than five times the number of male students, the following equation must be performed:
X + (5X + 2) = 50
6X + 2 = 50
6X = 50 - 2
X = 48/6
X = 8
Thus, the number of male students is 8, while the number of female students is 42.
Currently there are 691,255 trees in a national forest. A park ranger discovered that an untreatable disease is killing the
trees at a rate of 1.5% every year.
Lett represent the number of years after the current date. Determine the inequality that can be used to model when there
will be no more than 621,859 trees, and then solve the inequality for t.
The inequality which will represent the disease killing of trees in the national forest is 691255[tex]0.985^{t}[/tex]<621859 and the value of t is t<7.
What is inequality?An inequality is just like an equation which is presented in greater than sign, less than signs. It also shows relationship between variables like an equation does.
How to form inequality?Total trees present in the beginning=691255
rate at which trees are killed by untreatable disease=1.5%
So the inequality can be formed as under:
691255[tex](1-0.015)^{t}[/tex]<621859
[tex](0.985)^{t}[/tex]<621859/691255
[tex](0.985)^{t}[/tex]<0.89960
[tex](0.985)^{t}[/tex]<[tex](0.985)^{7}[/tex]
By equating we find that t<7.
Hence if 691255 trees are present in the beginning then they will last for more than 7 years to reach 621859.

solve using elimination x+2y=4 -x-y=2
Answer:
x=-8 y=6
Step-by-step explanation:
Add the two equations together. This cancels the x and gets us y=6
Then substitute y in more the first equation which gets us -8
Answer: y = 6 x = -8
Step-by-step explanation:
X+2Y=4
-X-Y=2
(Combine like terms)
Y= 6
(Plug in 6 for y)
X+2(6)=4
X+12=4
X= -8
