Answer:

x = 16 degrees

Step-by-step explanation:

Since this is an isosceles triangle, both sides are the same. We then come up with the equation:

5x - 7 = 8x - 55

Next, we subtract 5x on both sides

5x - 7 = 8x - 55

-5x        -5x

____________

-7 = 3x - 55

Afterward, we add 55 on both sides:  

-7 = 3x - 55

+55      +55

___________

48 = 3x

Lastly, you divide 48 by 3 to get the answer 16!!

The expansion of ( 2x - y⁵)² using algebraic identity, as a polynomial is  4x² - 4xy⁵+ y¹⁰

Algebraic identities are the identities which aids in solving products or powers of algebraic expressions. Most common identities are :

(a+ b)² = a² + 2ab + b²

(a- b)² = a² - 2ab + b²

a² -b² = (a+ b) (a- b), where a and b can be variable or constants or algebraic expressions.

For expanding (2x - y⁵)²

Use identity (a-b)² = a²-2ab+b², let a = 2x and b = y⁵

Then, ( 2x - y⁵)² = (2x)² - 2(2x)( y⁵) + (y⁵)²

⇒  ( 2x - y⁵)²  = 4x² - 4xy⁵+ y¹⁰

Therefore, the standard form of  ( 2x - y⁵)² as a polynomial is  4x² - 4xy⁵+ y¹⁰

Answer:

y = 2x

Step-by-step explanation:

I am basing this off of your straight line that you drew.

Slope is found by using [tex]\frac{rise}{run}[/tex] . This means that you change in your y-axis divided by change in your x axis.

This can also be modeled by Δy/Δx

I used point (0,0) and the peak of the slope (100,200)

Your line starts at 0 and rises 200 and runs to the right 100.

Thus, you can write:

y = [tex]\frac{200}{100}[/tex] x

This simplifies to y = 2x

a=2cm. b=50cm. x=?

The number of Quarter coins that she has is 8 and the number of Dimes is 16.

It is given in the question that the woman has twice as many Dimes as the quarters in her purse.

We know that the value of Dimes is 0.10$ and the value of Quarters is

0.25 $

Let the number of Quarter coins is y and the number of Dimes coin be u.

According to the question above,

u = 2y  equation (i)

The total value z = 0.25y + 0.10u

Putting here the value of u from equation (i) we have,

z = 0.25y + 0.10(2y)

⇒ z = 0.25y + 0.20y

⇒ z = 0.45y equation (ii)

Now it has been mentioned that if the Dimes were Quarters and the Quarters were the Dimes, she would have $ 1.20 greater than she has now.

So we have,

z + 1.2 = 0.25u + 0.10y

Putting the value of u from above eqation (i),

z + 1.2 = 0.25(2y) + 0.10y

⇒ z + 1.2 = 0.50y + 0.10 y

⇒ z + 1.2 = 0.60y

Putting the value of z from equation (ii)

⇒ 0.45y + 1.2 = 0.60y

⇒ 0.45y - 0.60y = - 1.2

⇒ -0.15y = - 1.2

⇒ y = [tex]\frac{-1.2}{-0.15}[/tex]

⇒ y = 8

Therefore u = 2y

⇒ u = 2 x 8 = 16

Hence the number of Quarter coins is 8 and the number of Dimes is 16

Answer:

The answer is 35:19

Step-by-step explanation:

First what is a ratio?

A relationship between two quantities, normally expressed as the quotient of one divided by the other. For example, if a box contains six red marbles and four blue marbles, the ratio of red marbles to blue marbles is 6 to 4, also written 6:4. A ratio can also be expressed as a decimal or percentage.

So as a result

= There are 35 mangoes and 19 strawberries

And since we are comparing mangoes to strawberries

The answer would be

The graph of the inequality (x + y >1),  will be:

{(x^2+(y-1)^2-0.05)((x-1)^2+y^2-0.05)(x+y-1)=0 [-10, 10, -5, 5]} and we can shade right-side of the line.

As per the question statement, we are supposed to graph the inequality

x + y >1. So, first we solve for two points as an equation instead of an inequality to find the boundary line for the inequality.

For x = 0, y = 1 or (0,1)

For y = 0, x = 1 or (1,0)

So now we can graph the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.

The boundary line would be solid because the inequality contains "or equal to" clause.

Graph: {(x^2+(y-1)^2-0.05)((x-1)^2+y^2-0.05)(x+y-1)=0 [-10, 10, -5, 5]}

We can shade right-side of the line.

Because the inequality operator lacks a "or equal to" phrase, the boundary line will be altered to a dashed line.

Answer:  The equation is written as:   " 7x  +  28  =   8  −  3x " .
  The value for x , when the equation is solved, is:  " -2 ."

Step-by-step explanation:

Let the "unknown number" be represented by the variable, x ;

7 (times) the [sum of: (x + 4)] ; (is the same as):  8 [decreased by]:

  3(times)x ;  
Rewrite:    " 7(x + 4) = 8 − 3x ".   This is the written expression.

____
Now, if we wish to "solve for x" ;
Let's examine the 'left-hand side' of the equation:
     7(x + 4)  ;

Note the 'distributive property' of multiplication:
  a(b + c) = ab + ac ;

____
 So:  7(x + 4) = 7*x + 7*4 =  7x + 28 ;

Now, let's write the entire equation:
  7x + 28 = 8 − 3x  ;
Let's add 3x , and subtract 8 ;  from Each Side of the equation:

 7x + 28 + 3x − 8 = 8  + 3x − 8 ;

→ 7x + 3x + 28 − 8 = 8 − 3x + 3x;

 to get:
 10x + 20  = 0 ;

Now:  Subtract 20 from Each Side of the equation:
  10x + 20 − 20 = 0 − 20 ;

to get:
   10x = -20 ;  Now, divide both sides of the equation by 10 ;

to isolate x on one side of the equation; & to solve for x :

    10x/10 = -20/10 ;
to get:  " x = - 2 " .
____
Alternate method:
 10x + 20 = 0 ;

Divide the Entire Equation by 10 ;

(10x + 20) / 10 = 0____ ;

 to get:  (10x/10) + (20/10) = 0 ;

  →  x + 2 = 0  ;

Now subtract 2 from each side of the equation;

 to isolate x on one side of the equation; & to solve for x :

     x + 2 − 2 = 0 − 2 ;

to get:  " x  =  -2 " .

The relationship between x and y is y = 0.25x + 1.

Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form. One of the formulas used to get a line's equation is the slope-intercept formula. Y = mx + b is the slope-intercept formula for a line with slope m and y-intercept b. Any point on the line is (x, y) in this case.

Given,

A basket with 4 apples weighs 2 pounds.

Slope intercept form:

y = mx + b

Equation:

2 = 4m +b ..(1)

A basket with 12 apples weighs 4 pounds

4 = 12m + b ... (2)

Solving,

2 = 4m + b

4 = 12m + b

4 = 8m

Divide the second equation by 8:

2 = 4m + b

m = 0.25

b = 1

The relationship between x and y is y = 0.25x + 1.

The amount of money that June has is $40 and Maria has $400. The total amount is $440.

From the information, John has $400 June has 1/10 of that and June has 0.1 of Maria’s money.

Therefore the amount that June has will be:

= 0.1 × John's money

= 40

June has 0.1 of Maria’s money. Let Maria's money be x. Therefore, 0.1 × x = 40

0.1x = 40

Answer:

x = 45

y = 20

Step-by-step explanation:

Since the two horizontal lines are parallel

angles with measures of 6y and 3y are supplementary angles and add up to 180°

So 6y + 3y = 180
9y = 190

y = 20

Similary 2x and 90 are supplementary angles

2x + 90 = 180

2x = 90°

x = 45

Answer:

x=45 y=20

Step-by-step explanation:

you can tell x is 45 because is is a right angle and those are 90 degrees.

Answer:

x = 25 when y = 8

Step-by-step explanation:

If y is inversely proportional to square root of x we write it as
[tex]y \propto \dfrac{1}{\sqrt{x}}[/tex]

This is also equivalent to
[tex]y = k \dfrac{1}{\sqrt{x}} \;\;\;\;\ \text{ [1]}[/tex]

where k is a constant known as the constant of proportionality

Given y = 10 when x = 16 we can find k by substituting for y and x in [1]

[tex]\rightarrow 10 = k\dfrac{1}{\sqrt{16}}\\\\\rightarrow 10 = k \dfrac{1}{4}\\\\\drightarrow 40 = k \:\:\:\: \text{by multiplying both sides by 4}\\\\\text{which can be written as }\\\\k = 40\\[/tex]

So constant of proportionality k = 40

To find x when y = 8, substitute y and k in [1] to get
[tex]y = k \dfrac{1}{\sqrt{x}}\\\text{Multiply both sides by \sqrt{x} and divide by y at the same time to get}\\\\\sqrt{x} = \dfrac{k}{y}[/tex]

Dividing both sides by y and multiplying by √x gives us
[tex]\sqrt{x} = \dfrac{k}{y}\\\\\text{Substituting k = 40, y = 8}:\\\\\sqrt{x} = \dfrac{40}{8}\\\\\sqrt{x}= 5\\\\\text{Squaring both sides: }\\\\(\sqrt{x})^2 = 5^2\\\\x = 25 \;\;\;\text{since $(\sqrt{x})^2$ = x}[/tex]

The answer is

x = 20

Formulate y=k/x based on the following criteria.

Replace: 10= k/16

Change the sides so that k/16 = 10.

Subtract the coefficient of the variable from both sides of the equation: k = 10×16

Determine the quotient or product: k = 160

Replace with y = 160/x.

Replace with: 8 = 160/x

The denominator cannot be zero if the fraction is defined: as x ≠ 0

As the domain, append the inequality: 8= 160/x, x≠0

Divide the common denominator by both sides of the equation: 8x = 160x/x, x≠0

8x=160x/x, where x ≠ 0. Reduce the fraction.

By the variable's coefficient, multiply both sides of the equation (x=160÷8, x ≠ 0).
