6x+5

Step-by-step explanation:

2x-5+x-5=3x-10+2x+15=5x+5+x=6x+5

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

Step-by-step explanation:

x-9=3

basically 3 + 9=12 so 12-9=3

The mathematical sentence expresses the information.

g - 9 = 3

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The number of gallons of gas that were in the tank minus 9 leaves 3 gallons.

The mathematical sentence expresses the information.

g - 9 = 3

Thus,

The expression is g - 9 = 3.

64 - (16/3)= 208/3

I need help understanding HOW the answer to this is 208/3. Please give an explanation ASAP!!

Answers

To make it easier divide 208/3, which is 69.3. Importantly, divide -16 by 3 which is 5.3. Now solve 64- (-5.3), which equals 69.3

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

Which graph shows a function and its inverse?

Answers

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.

Answers

Answer:

a = 3, b = 2

Step-by-step explanation:

GivenP(x) = ax² + bx + 1P(1) = 6 and P(-1) = 2To find Values of a and bSolution

Substitute the values of x:

P(1) = 6

6 = a(1)² + b(1) + 16 = a + b + 1a + b = 5

P(-1) = 2

2 = a(-1)² + b(-1) + 12 = a - b + 1a - b = 1a = b + 1

Substitute a in the previous equation:

a + b = 5b + 1 + b = 52b = 4b = 2

Then finding a:

a = b + 1a = 2 + 1 a = 3

So a = 3, b = 2

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

Answers

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

Answers

Answer:

22.7.....feet^2

Step-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

Answer:

m = 10

Step-by-step explanation:

20 + 3m = 5m

Subtract 20 from both sides

Subtract 5m on both sides

-2m = -20

Divide both side by -2

-2m/-2 = -20/-2

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?

Answers

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

Which equation represents a line parallel to the y-axis?
A. y = x
B. x = 4
C. y = 4
D. y = x +4

Answers

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 =a

By 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

Therefore,

The equation of the line that is parallel to the y-axis is option B. x = 4

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.
