which decimal is equivalent to 2/3?​

Answer:

x = -12.57

Step-by-step explanation:

2x + 45 - 56 = 9x + 54 + 23

2x - 11 = 9x + 77

-11 = 7x + 77

-88 = 7x

x = -12.57

Answer:

m∡BCA = 57°

Step-by-step explanation:

find 'x' by adding all expressions and setting them equal to 360°

9x+1 + tx+12 + 10x-37 = 360

24x = 384

x = 16

Substitute 16 into 10x-37

160 - 37 = 123

m∡BCA is supplemental with 123°, therefore it measures 57°

Answer: The selling cost for Stefan bicycle = $114 and

the selling cost of a helmet = $18.

The total cost for Jin is 120% of the money spent.

Let us assume purchasing cost of a bicycle = $x.

Purchasing cost of a halmet = $y.

For bicycle

120% of x is $114  

=>  1.20 × x = 114

Dividing both sides by 1.20, we get

x=$95.

For helmet.

120% of y is $18.

=> 1.20 × y = 18.

Dividing both sides by 1.20, we get

y = $15.

Therefore, Stefan spent originally to buy a bike $95 and $15 to buy a helmet.

$114 - 95 = $19

$18 - 15 = $3.

Therefore, he made $19 by selling the bicycle and $3 by selling the helmet to Jin.

Answer:

x = 65

Step-by-step explanation:

straight line = 180 degrees

so

180 - 165 = 25

90 + 25 = 115 degrees

180 - 115 = 65 degrees

so

x = 65

Answer:

= 8n^2 +26n +6

Step-by-step explanation:

(4n+1)(2n+6)

= 8n^2 + 24n +2n +6

= 8n^2 +26n +6

The product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

To multiply the polynomials (4n+1)(2n+6), you can use the distributive property.

(4n+1)(2n+6) = 4n x 2n + 4n x 6 + 1 x 2n + 1 x 6

Applying the distributive property and simplifying each term:

= 8n² + 24n + 2n + 6

Combining like terms:

= 8n² + 26n + 6

Therefore, the product of the polynomials (4n+1)(2n+6) is 8n² + 26n + 6.

The expression showing the number of students in the drama club the next year is 15+d.

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given that, there are 20 students in a drama club,

5 of them will leave in next year, and d students will join,

We are asked to construct an expression to represent the total number of students in the drama club next year.

So, the present number of students in the club = 20

After next year = 20-5 = 15

After the joining = 15+d

Hence the expression showing the number of students in the drama club the next year is 15+d.

Step-by-step explanation:

I hope that is useful for you :)

Answer:

For example 1/1, 2/3 and 4/3

Step-by-step explanation:

There is a great way to generate rational numbers between other rational numbers using:

[tex]\textrm{If:~~~~~~} \frac{a}{b} < \frac{c}{d}\vspace{7pt}\\\textrm{Then:~} \frac{a}{b} < \frac{a+c}{b+d} < \frac{c}{d}[/tex]

So we know that (1+3)/(2+2) is between 1/2 and 3/2 without checking.

(1+3)/(2+2) = 1/1, so we got our first rational number.

Lets continue by finding numbers between 1/2 and 1/1; and 1/1 and 3/2

(1+1)/(2+1) = 2/3

(1+3)/(1+2) = 4/3

We could also look for a number between 1/2 and 2/3 and find

(1+2)/(2+3) = 3/5

And so on, so forth :)

According to graph, the coordinates of the vertex of the parabola are (-4,-4).

"A parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped."

"The vertex of a parabola is the point at the intersection of the parabola and its line of symmetry. For a parabola whose equation is given in standard form, the vertex will be the minimum (lowest point) of the graph and the maximum (highest point) of the graph.
