5x - 3y = 11 ⇒ 5x - 3y = 11  ⇒   5x - 3y = 11
  x - 2y = 2   ⇒ -5(x - 3y) = 2 ⇒ <u>-5x + 15y = 2</u>
                                                           <u>12y</u> = <u>13</u>
                                                            12     12
                                                             y = 1 1/12
                                                 5x - 3(1 1/12) = 11
                                                 5x - 3 1/4 = 11
                                                <u>      +3 1/4    +3 1/4</u>
                                                            <u> 5x</u> = <u>14 1/4</u>
                                                              5          5
                                                               x = 2 17/20
                                                 (x, y) = (2 17/20, 1 1/12)

Can someone help me, im so confused and dont know where to begin how do i find x please help :(
drek231 [11]

I would say D :)

You can see the lines on the side of the triangle which means congruent, so you can see that both angles inside are the same. A triangle is 180°, so subtract 30° and divide that answer by two. You'll get 75°.

I love to help with geometry, so I'll help if you need anything else!

Indique la propuesta correcta con respecto a los instrumentos de medida: a) El Voltímetro A.C. Mide valor medio b) El Voltímetro
Gre4nikov [31]

Answer:

Las propuestas correctas son;

a) Voltímetro de CA Mide el valor medio

La magnitud del voltaje de corriente alterna varía periódicamente con el tiempo, dentro de un rango dado

El voltímetro de CA proporciona la lectura y, por lo tanto, mide el valor medio del voltaje, el voltaje pico o el R.M.S. valor de la tensión

b) El voltímetro de CC mide el valor máximo

Los valores de voltaje de un circuito de corriente de CC se fijan con el tiempo y, por lo tanto, el voltímetro de CC mide los voltajes máximos en el circuito.

c) El amperímetro de CA mide el valor medio

Similar a la medición de voltaje de CA, el amperímetro de CA mide el valor de corriente medio

d) El A.C. mide el valor efectivo

La raíz cuadrada media o R.M.S. valor es el valor medido por un R.M.S. Medidor de A.C.

e) El D.C. se conecta en paralelo

Todos los voltímetros se colocan en paralelo con el circuito desde el que se va a medir el voltaje.

Sin embargo, un amperímetro de CC está conectado en serie

one teacher wants to give each student 7/8 of a slice of pizza. If the teacher has 7 slices of pizza then how many students will
Crazy boy [7]

Answer:

The teacher can hand out pizza to 8 students.

Step-by-step explanation:

To find how many slices of pizza the teacher can hand out , you can divide 7 by 7/8 and round down the nearest whole number.

7 ÷ 7/8 = 8

8 is already a whole number. No need to round down.

The teacher can hand out pizza to 8 students.

To place an ad in the Harrisonburg newspaper it cost $100 for each 1/8 of a page used. How much would an advertisement cost if i
larisa86 [58]

Answer:

It would cost <u>$600</u> for an advertisement of  \frac{3}{4}  of a page.

Step-by-step explanation:

Given:

To place an ad in the Harrisonburg newspaper it cost $100 for each 1/8 of a page used.

Now, to find the cost of an advertisement 3/4 of a page.

So, to get the cost we use unitary method:

<em>If,  </em>\frac{1}{8}<em> of a page used cost = $100.</em>

<em>Then, 1 page used cost = </em>100\div \frac{1}{8}<em> = </em>\$800.<em />

<em>Thus,  </em>\frac{3}{4}<em>  of a page used cost</em> = 800\times \frac{3}{4} =\frac{2400}{4}=\$600.

Therefore, it would cost $600 for an advertisement of  \frac{3}{4}  of a page.
