1/5-3/4= 4/20-15/20= -11/20

Answer:

The answer is -11/20 aka b

Step-by-step explanation:

The value of the number for the expression seven is less than the quotient of a number and five is two​ is 45.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a number is seven less than the quotient of a number and five is two​.

The value of the unknown number will be calculated as,

x/5 - 7 = 2

x/5 = 9

x = 45

The common ratio is 1/2.

Given that

The sequence 200, 100, 50, 25.

The common ratio is determined by dividing the second term by the first term.

[tex]\rm Common \ ratio = \dfrac{Second \ Term }{First \ Term}[/tex]

Here, the second term is 100 and the first term is 200.

Then,

The common ratio is;

[tex]\rm Common \ ratio = \dfrac{Second \ Term }{First \ Term}\\\\\rm Common \ ratio = \dfrac{100}{200}[/tex]

[tex]\rm Common \ ratio = \dfrac{1}{2}[/tex]

The common ratio between third term 50 and second term 100 is;

[tex]\rm Common \ ratio = \dfrac{Second \ Term }{First \ Term}\\\\\rm Common \ ratio = \dfrac{50}{100}\\\\\rm Common \ ratio = \dfrac{1}{2}[/tex]

Hence, the common ratio is 1/2.

Answer:

y = 2/5x - 3

Step-by-step explanation:

First, we have to know what the slope is. Being perpendicular to -5/2, the slope becomes 2/5.

Then, you substitute the slope and given point into the equation to find the y-intercept.

y = 2/5x + b

(-5) = 2/5(-5) + b

(-5) = (-2) + b

b = -3

So, the equation is

y = 2/5x - 3

The equation of the line perpendicular to y = -5/2x + 1 that passes through the point (-5, -5) is y = 2/5x - 3.

We have the Equation,

y= -5/2x + 1

Here, the slope is -5/2.

Since perpendicular line have negative reciprocal of the slope of the given line.

So, the slope of the line perpendicular is 2/5.

Using point-slope form of the equation to find the equation of the perpendicular line.

The point-slope form is given by:

y - y1 = m(x - x1)

Using the point (-5, -5) and the slope 2/5,

y - (-5) = 2/5(x - (-5))

y + 5 = 2/5(x + 5)

y + 5 = 2/5x + 2

y = 2/5x - 3

Therefore, the equation of the line perpendicular to y = -5/2x + 1 that passes through the point (-5, -5) is y = 2/5x - 3.

Answer:

what is the name of the amount that is not constant

Step-by-step explanation:

Answer:

542

Step-by-step explanation:

-3, 2, 7, 12

-3 + x = 2 x = 5

2 + x = 7 x = 5

7 + x = 12 x = 5

If you want to find the 3rd term in the sequence and you start with the first number, then you do this:

-3 + (2 * 5) = -3 + (10) = 7

The same goes for the 110th term:

-3 + (109 * 5) = -3 + (545) = 542

The formula to find the nth term is:

f(n) = n(0) + (n-1) * 5

Suppose n(0) = -3 then

f(110) = -3 + {(110-1) * 5}

f(110) = -3 + {(109) * 5}

f(110) = -3 + (545) = 542

You can simplyfy f(n) = n(0) + (n-1) * 5

f(n) = n(0) + (n-1) * 5

f(n) = n(0) + (5n-5)

f(n) = n(0) + 5n - 5

f(110) = -3 + (5 * 110) - 5

f(110) = -3 -5 + (550)

f(110) = - 8 + 550

f(110) = 542

Answer:

129

Step-by-step explanation:

The sum of all angles in any quadrilateral is 360°

so, you can make the following equation:

71 + 48 + 112 + x = 360

231 + x = 360

Subtract 231 from both sides of the equation

231 + x - 231 = 360 - 231

x = 360 - 231

x = 129

Step-by-step explanation:

The given image is a trapezium. A trapezium is a quadilateral. Hence , it's sum of angles is 360°

To solve for x ;

[tex]71° + 48° + 112 ° + x° = 360° \\ 231 + x = 360 \\ x = 360 - 231 \\ x = 129[/tex]

the equation of the line is y = 3x - 5

Because of PEMDAS, Simplify 15x72 first. That will bring you to 1080. After that we add 6 to the 1080 because you always do Multiplication first. Your answer would be 1086 if you followed PEMDAS correctly.

PEMDAS:

1. Parentheses

2. Exponents

3. Multiplication

4. Division

5. Addition

6. Subtraction

That's the order of operations if you ever want to know what to do first.

====================================

Work Shown:

Plug in (x,y) = (3,0)

ax - 8y = 15

a(3) - 8y = 15 .... replace x with 3

3a - 8(0) = 15 ... replace y with 0

3a - 0 = 15

3a = 15

a = 15/3

a = 5

The equation updates to 3x - 8y = 15.
