Answer:

The cost of both shirts and jeans after discount is $71

Step-by-step explanation:

Given as :

The number of shirts bought = 3

The number of pair of jeans bought = 2

The cost of each shirt before discount = $12

The cost of each pair of jeans before discount = $19

The discount on total cost = $3

Let The total cost paid = $A

Now, According to question

Total cost of items = number of shirts bought × cost of each shirt before discount + number of pair of jeans bought × cost of each pair of jeans before discount

Or, A = 3 × $12 + 2 × $19

Or, A = $36 + $38

Or, A = $74

Again

Discount of $3 is applied on total cost

So, The cost of items after discount = $74 - $3

Or, The cost of items after discount = $71

Hence, The cost of both shirts and jeans after discount is $71 Answer

3/4(12x−8)+3=10−1/2(6x+2)

Aleonysh [2.5K]

Answer:

$x=1$

Step-by-step explanation:

$\frac{3}{4}(12x-8)+3=10-\frac{1}{2}(6x+2)$

$(9x-6)+3=10-(3x+1)$

$9x-6+3=10-3x-1$

$9x-3=9-3x$

$9x=12-3x$

$12x=12$

$x=1$

Un paracaidista que pesa 70 N es lanzado de un avión. halla su masa

77julia77 [94]

Answer:

La masa del paracaidista es 7.14 Kg

Step-by-step explanation:

Peso y Masa

La masa de un objeto es una medida de la cantidad de material que el objeto posee. Sus unidades más comunes son el Kg, gr, lb, Ton.

El peso de un objeto de masa m es la fuerza con la cual la Tierra atrae al objeto a través de la aceleración de gravedad g. Sus unidades son iguales a las de cualquier fuerza, es decir, Nw, Kgf, Dina. Su fórmula es:

P=m.g

Si tenemos el peso P=70 N, podemos calcular la masa, despejándola de la fórmula:

$\displaystyle m=\frac{P}{g}$

Sustituyendo los valores:

$\displaystyle m=\frac{70}{9.8}=7.14\ Kg$

La masa del paracaidista es 7.14 Kg

Find the length of each side of the triangle determined by the three points P1,P2, and P3. State whether the triangle is an isos

Tanya [424]

Answer:

The triangle is both an Isosceles triangle and a right triangle.

Step-by-step explanation:

Given the vertices of a triangle.

$P_{1} = (- 1, 4)$

$P_{2} = (6, 2)$ and

$P_{3} = (4, - 5)$

We find the distance between all the points to determine the length of each side of the triangle.

Distance between any two points, say, $(x_1, y_1)$ and $(x_2, y_2)$ is:

$\sqrt{\bigg ( \textbf{x}_{\textbf{2}} \hspace{1mm} \textbf{- x}_{\textbf{1}} \bigg )^{\textbf{2}} \textbf{+} \bigg( \textbf{y}_{\textbf{2}} \hspace{1mm} \textbf{- y}_{\textbf{1}} \bigg)^ {\textbf{2}}$
