Answer:
A = 197 tons
B = 84 tons
Step-by-step explanation:
Given Equations: A + B = 281 A - B = 113
A = 113 + B
113 + B + B = 281
2B = 281 - 113
2B = 168
B = 84
A = 113 + 84
A = 197

Answer:
2.5
Step-by-step explanation:
Add up the 5s of the left side first and you will get 25. Then you add up the 5s on the otherside and you will get 10. Subtract the 10 from the 25 to get 15. Finally, divide 15 by 6 to get the weight of each triangle, 2.5
1: 5 x 5 = 25
2: 5 x 2 = 10
3: 25 - 10 = 15
4: 15/6 = 2.5
The weight of each triangle is 2.5
Have an amazing day!
PLEASE RATE!!
Answer: 2.5
Step-by-step explanation:
What we know:
Both sides need to be equal, and one side already has a constant defined value.
That value is 25 (units)
How to solve:
By using a simple algebraic equation, we can find the value of a triangle's weight. X will represent a square's weight, and y will represent a triangle's weight.
Process:
Set up equation 5x = 2x + 6y
Substitute 5(5) = 2(5) + 6y
Simplify 25 = 10 + 6y
Cancel out -10 -10
15 = 6y
Separate variable /6 /6
Solve 2.5 = y
Solution: y (triangle weight) = 2.5
You can check this by adding 2.5 6 times (15) to 5 2 times (10). This will equal 25, which would balance out the other side

Answer:
ø=14.48⁰ and. y=75.52⁰
Explanation:
angle thetha = 14.48⁰
sinø=opposite/hypotenuse
sinø=12/48
ø=sin¹(12/48)
ø=14.48
y=180⁰-(14.48⁰+90⁰)
y=75.52⁰

Answer:
y = 37
Step-by-step explanation:
the 3 angles lie on a straight line and sum to 180°
sum the 3 angles and equate to 180
y + 29 + 40 + 2y = 180 , that is
3y + 69 = 180 ( subtract 69 from both sides )
3y = 111 ( divide both sides by 3 )
y = 37

Step-by-step explanation: julie spent 36 dollars in the dress while mindy spent 32 dollars
Julie spend [tex]\$4[/tex] more money than Mindy on the dress.
What is off/Discount?Off/Discount is an amount that is subtracted from the regular price of an item.
The original price of dress [tex]= \$39.99[/tex]
Julie buys the dress for [tex]10\%[/tex] off at its original price.
So,
Julie buys the dress for [tex]= 39.99-(39.99*\frac{10}{100} )[/tex]
[tex]= \$35.991[/tex]
Mindy buys the same dress for [tex]20\%[/tex] off at its original price.
Mindy buys the same dress for [tex]= 39.99-(39.99*\frac{20}{100} )[/tex]
[tex]=\$31.992[/tex]
So,
Julie spend more money than Mindy on the dress [tex]=35.991-31.992[/tex]

Una compañía de transporte público cobra " "x" " por transportar cierta mercancía 20 kilómetros y " "z" " por transportar la misma mercancía 25 kilómetros. A) Determine la relación entre la tarifa total y la distancia recorrida, suponiendo que es lineal. B) ¿Cuál es la tarifa mínima por transportar esta mercancía? C) ¿Cuál es la cuota por cada kilómetro que la mercancía es transportada?" x = $190. 00 z = $242. 0. Prueba con las sugerencias que aparecen más abajo o introduce una consulta nueva
Utilizando los dos puntos dados, veremos que la relacion lineal es:
A) y = ($10.4 /km)*x -$18A) y = ($10.4 /km)*x -$18B) -$7.6C) $10.4 /km¿Como encontrar la relacion lineal?Una ecuación lineal se escribe como:
y = a*x + b
donde a es la pendiente y b es la ordenada al origen.
Sí sabemos que una linea pasa por los puntos (x₁, y₁) y (x₂, y₂), entonces la pendiente va a ser:
a = (y₂ - y₁)/(x₂ - x₁).
Aca tenemos los dos puntos:
(20km, $190)
(25 km, $242)
Entonces la pendiente será:
a = ($242 - $190)/(25km - 20km) = $10.4 /km
y = ($10.4 /km)*x + b
Para obtener el valor de b, usamos uno de los puntos. Evaluando en x = 20km deberiamos obtener y = $190, entonces:
$190 = ($10.4 /km)*20km + b
$190 = $208 + b
$190 - $208 = b = -$18
Entonces la ecuación es:
y = ($10.4 /km)*x -$18
B) La tarifa minima es lo que obtenemos con x = 1 km, entonces es:
y = ($10.4 /km)*1 km - $18 = -$7.6
Notar que da un valor negativo, lo que indica que la relación quizas no es lineal.
C) La cuota por kilometro es la pendiente de la relación lineal, en este caso será: $10.4 /km.

Answer:
x=5
Step-by-step explanation:
An isosceles trapezoid has two pairs of congruent base angles. This means angle F has to equal angle E. So we have 2x^2+21=3x^2-4. Move the variables to one side and we get 25=x^2. Square root both sides and we get two values x=5 and x=-5. Since angles cannot necessarily be negative, we only want the positive value. In this case x=5.
