6x+8y=20 4x-6y=12 please​

Answer»

Answer:

6x+8y=20

simplifying

6x + -8y = 20 Solving 6x + -8y = 20 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '8y' to each side of the equation. 6x + -8y + 8y = 20 + 8y COMBINE like terms: -8y + 8y = 0 6x + 0 = 20 + 8y 6x = 20 + 8y Divide each side by '6'. x = 3.333333333 + 1.333333333y Simplifying x = 3.333333333 + 1.333333333y

4x-6y=12

First, SUBTRACT 6y from each side of the equation to ISOLATE the x term while keeping the equation balanced:

4x+6y−6y=12−6y

4x+0=12−6y

4x=12−6y

Now, divide each side by 4 to solve for x while keeping the equation balanced:

4x4=12−6y4

4x4=12−6y4

x=12−6y4

Or

x=124−64y

x=3−2×32×2y

x=3−2×32×2y

x=3−32y

The total surface area of a closed cone is 176 CM square if its radius is 4 cm find its slantheight​

Answer»

S O L U T I O N :

Given,

  • Total SURFACE area of a closed cone is 176 cm².

  • Radius (R) of a closed cone is 4 cm.

To Find,

  • The slant height (l) of a closed cone.

Explanation,

We know that,

Total surface area of a cone = πr(l + r)

[ Put the values ]

=> 176 = 3.14 × 4 (l + 4)

=> 176 = 12.56(l + 4)

=> 176 = 12.56l + 50.24

=> 176 - 50.24 = 12.56l

=> 125.76 = 12.56l

=> l = 125.76/12.56

=> l = 10 cm

THEREFORE,

The slant height of a closed cone is 10 cm.

The cost of 2 kg of apples and 1 kg of grapes is Rs 360 and the cost of 1 Kg of apples and 3kg of grapes is Rs.380. Form linear equation to represent this situation.please anybody help its urgent

Answer»

ANSWER:

ANSWER

X 65 55 45 35

y 20 40 60 80

Let the cost of 1 kg of APPLES be x and that of 1 kg be y

So the algebraic representation can be as follows:

2x+y=160

4x+2y=300⇒2x+y=150

The situation can be represented graphically by plotting these two equations.

2x+y=160⇒y=160−2x

x 70 60 50 40

y=160−2x 20 40 60 80

2x+y=150⇒y=150−2x

x 65 55 45 35

y=150−2x 20 40 60 80

We can see that the lines do not intersect anywhere, i.e. they are parallel. Hence we can not arrive at a solution.

15. Find the area of triangle whose vertices are (2, 3), (– 1, 0) and (2, – 4).​

Answer»

Answer :

  • AREA of the triangle is 10.5cm².

Given :

  • VERTICES of a triangle are (2 , 3), (-1 , 0), (2 , -4).

To Find :

  • Area of the triangle.

Solution :

Let

ABC be the triangle in which

  1. A = (2 , 3)
  2. B = (-1 , 0)
  3. C = (2 , -4)

Here

  • x1 = 2
  • x2 = -1
  • x3 = 2
  • y1 = 3
  • Y2 = 0
  • y3 = -4

As we know that

Area of a triangle is

  • ½ [x1 (y2 - y3) + x2 (y3 - y1) + x3 (y1 - y2)

Put the values in the formula

Now,

According to question :

→ 1/2 [ 2 {0 - (-4)} + (-1) {(-4) - 3} + 2 {3 - 0) ]

→ 1/2 [ 2 × 4 + (-1) × (-7) + 2 × 3 ]

→ 1/2 [ 8 + 7 + 6 ]

→ 1/2 × 21

→ 21/2

10.5cm²

Hence, the area of the triangle is 10.5cm².
