Answer:
8x + 10 is the expression for our perimeter
Step-by-step explanation:
2x -5 - x - 5 = x - 10. So the length of the right side is x - 10.
2x + 15 - x = x + 15, so the length of the other missing side is x + 15.
Now we combine like terms and simplify to get the perimeter
(2x -5) + (x) + (x-5) + (x+15) + (x-10) + (2x + 15)
Simplified we get 8x + 10 as the expression for our perimeter
In parallelogram LMNO, MP = 21 m, LP = (y + 3) m, NP = (3y – 1) m, and
OP = (2x – 1) m.
Parallelogram L M N O is shown. Diagonals are drawn from point M to point O and from point L to point N and intersect at point P.
What are the values of x and y?
x = 10 m, y = 1 m
x = 10 m, y = 2 m
x = 11 m, y = 1 m
x = 11 m, y = 2 m
Answer:
x = 11 m, y = 2 m ⇒ D
Step-by-step explanation:
In the parallelogram, diagonals bisect each other
∵ LMNO is a parallelogram
∵ OM and LN are its diagonals
∵ OM ∩ LN at point P
→ By using the fact above
∴ P is the mid-point of OM and LN
∴ OP = MP and LP = NP
∵ OP = MP
∵ OP = 2x - 1
∵ MP = 21
∴ 2x - 1 = 21
→ Add 1 to both sides
∴ 2x = 22
→ Divide both sides by 2
∴ x = 11 m
∵ LP = NP
∵ LP = y + 3
∵ NP = 3y - 1
∴ y + 3 = 3y -1
→ Add 1 to both sides
∴ y + 4 = 3y
→ Subtract y from both sides
∴ 4 = 2y
→ Divide both sides by 2
∴ 2 = y
∴ y = 2 m

Find the area of a rectangle with a length of 5 feet and a width of 4 5/9 feet. Write the answer as a fraction and as a decimal. Use three consecutive points to show repeating decimals, if necessary
Answer:
22.7.....feet^2Step-by-step explanation:
Step one:
given data
we are told that the length is 5 feet
and also the width is given in fractional form as 4 5/9
let's convert to decimal 4+0.55= 4.555555555555555
the width is a repeating decimal hence width = 4.5...feet
Step two:
The expression for the area is
A= lenght * width
A= 5*4.5
A=22.7...feet ^2
The area of the rectangle is 22.7 feet^2

20+3m=5m What does m equal?
Answer:
M= 10
Step-by-step explanation:
I edited it so now it should be right
Answer:
m = 10
Step-by-step explanation:
20 + 3m = 5m
Subtract 20 from both sides
3m = 5m - 20
Subtract 5m on both sides
-2m = -20
Divide both side by -2
-2m/-2 = -20/-2
= m = 10

Which graph shows a function and its inverse?
A graph depicts the inverse function with the help of a vertical line test. The lines passes through the origin and have a slope. The line y = x is a reflection of the original path.
Example: f(x) = 2x + 5 = y. Then, g(y) = (y-5)/2 = x is the inverse of f(x). Reflecting over the y and x gives us the function of the inverse.Hence the option A is correct.

Five is the quotient of 120 divided by some number. What is the number? 20 24 115 125
Your answer is 24! If you work backwards and divide 120 by 5, you get 24. To check your work, multiply 24 by 5 to get 120. Hope this helps! Please mark brainliest and have an amazing rest of your day. Stay safe! xx
The number 24 divides 120 gives the Quotient 5.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
Quotient = 5
Dividend = 120
Divisor = x
So, Dividend = Divisor . Quotient
120 = x(5)
5x = 120
x= 120/5
x= 24.
Thus, the required number is 24.

Selma cannot remember her locker number! She knows that her locker number is prime, and that it is a factor of 435. What are all of Selma's possible locker numbers?
Answer:
Possible locker numbers for Selma are: 3, 5 and 29
Step-by-step explanation:
First of all, let us have a look at the definition of a prime number.
A prime number is a number which is divisible either by 1 or the number itself.
No other number divides the prime number other than 1 and the number itself.
Now, let us factorize the given number 435 and let us observe the what all possibilities are there.
[tex]435 = 3\times 145[/tex]
Factorizing 145 further:
[tex]435 = 3\times 5\times 29[/tex]
No further factors are possible.
Therefore 3, 5 and 29 are the prime factors of 435.
So, the answer is:
Possible locker numbers for Selma are: 3, 5 and 29

A police car is approaching a right-angled intersection from the north at 35 mph, and a speeding car is heading east at 30 mph. When the police car is 0.75 miles north of the intersection and the speeding car is 1 mile to the east, what is the rate that the distance between the police car and car is changing?
Answer:
The rate that the distance between the police car and car is changing = 3 m/s
Step-by-step explanation:
The given speed of the police car = 35 mph
The speed of the speeding car = 30 mph
The position of the police car = 0.75 miles north
The position of the speeding car = 1 miles east
The distance of the police car from the speeding car, d = √(0.75² + 1²) = 1.25
d² = x² + y²
2d·dd/dt = 2x·dx/dt + 2·y·dy/dt
Where;
dx/dt = 30 mph
dy/dt = -35 mph
x = 1
y = 0.75
Substituting gives;
2×1.25 ×dd/dt = 2×1×30 - 2×0.75×35
2×1.25 ×dd/dt = 7.5
dd/dt = 7.5/2.5 = 3
dd/dt = 3 m/s
The rate that the distance between the police car and car is changing = dd/dt = 3 m/s
Answer:
The answer is increasing by 3 mph

Hi. I need help with these questions.

Answer:
a = 3, b = 2Step-by-step explanation:
GivenP(x) = ax² + bx + 1P(1) = 6 and P(-1) = 2To find Values of a and bSolutionSubstitute the values of x:
P(1) = 6
6 = a(1)² + b(1) + 16 = a + b + 1a + b = 5P(-1) = 2
2 = a(-1)² + b(-1) + 12 = a - b + 1a - b = 1a = b + 1Substitute a in the previous equation:
a + b = 5b + 1 + b = 52b = 4b = 2Then finding a:
a = b + 1a = 2 + 1 a = 3So a = 3, b = 2
64 - (16/3)= 208/3
I need help understanding HOW the answer to this is 208/3. Please give an explanation ASAP!!
Answer:
64 - (-16/3) = 208/3
Step-by-step explanation:
I think the problem may be written incorrectly. For this to be correct, it must be 64- (-16/3) = 208/3.
To get 203/3 you have to find a common denominator because in order to subtract (or add) fractions, they must have the same denominator.
However, 64 does not have the same denominator as -16/3!!
We can write 64 as 64/1, and to give it the same denominator as -16/3, we need to multiply the denominator by 3
BUT we have to do the same thing to the numerator!!! We can't only change the denominator. If one changes, the other has to change too.
So lets multiply the numerator and denominator by 3. 64 x 3 = 192
1 x 3 = 3
Now we have 192/3
Subtracting a negative number is the same as adding. So instead we can write 192/3 + 16/3
Add 192 and 16 to get 208, so now you have 208/3

A. y = x
B. x = 4
C. y = 4
D. y = x +4
The equation of the line that is parallel to the y-axis is option B. x = 4
What are parallel lines:Parallel lines are two or more lines that are always the same distance apart and never intersect, even if they are extended infinitely in both directions.
In other words, they have the same slope but different y-intercepts, which means that their steepness or inclination is the same.
Note:
The equation of the line that is parallel to the x-axis is y = a. The equation of the line that is parallel to the y-axis is x =aBy the above observations
The equation of the line that is parallel to the y-axis is x = a
From the given options,
The equation of the line that is in the form of x = a is x = 4
