Solve for X If you have 2x+3

Mathematics
1 answer:
daser333 [38]3 years ago
5 0

Answer:

in the explanation

Step-by-step explanation:

According to the triangle midsegment theorem (if these points are midpoints),

2x + 3 is two times longer than 7, meaning it's 14.

2x+3=14

2x=11

x = 11/2

If there is an option for not enough info given, that should be right as it doesn't actually say that they are midpoints

By applying the law of sines.

\frac{GH}{sin \ J} =  \frac{GJ}{sin \ H}

Given:
<span>GJ = 10 , ∠J =45° , ∠H = 31°

∴ </span><span>\frac{GH}{sin \ 45} =  \frac{10}{sin \ 31}

∴ GH = 10 * sin 45° / sin 31° ≈ 13.7 m

Observa las dimensiones del siguiente portarretrato, y escribe la expresión que determina el área disponible para la fotografía
777dan777 [17]

Answer:

<h2>D</h2>

Step-by-step explanation:

The dimensions of the portrait are attached.

The total area of the portrait is represented by its width 5+x and its length x+1.

We know by definition that the area of a rectangle is

A= w \times l

Where w is the width and l is the length.

Using the given expressiones, we have

A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5

Therefore, the right answer is D.

ABC Bookstore sells packages of books that include both new and used books. New books cost $20 and used books cost $8. The books
evablogger [386]

Answer:

There are 14 new books and 22 old books in the package.

Step-by-step explanation:

New books cost $20 and used books cost $8. The bookstore wants to sell packages that have 36 books total, and the store charges $456 for each package.

If the number of new books in the package is x and that of old books in the package is y, then we can write two simultaneous equations as

x + y = 36 ........... (1) and

20x + 8y = 456

⇒ 5x + 2y = 114 ............ (2)

Now, solving equations (1) and (2) we get,

5x + 2(36 - x) = 114

⇒ 3x + 72 = 114

⇒ 3x = 42

⇒ x = 14

Then, y = 36 - x = 22.

Therefore, there are 14 new books and 22 old books in the package. (Answer)
