x+y=94 -> y=94-x
x-y=12
Substitute: x-(94-x)=12
Distribute: x-94+x=12
Simplify: 2x=106
Solve: x=53

Plug x back into equation
x-y=12
53-y=12
y=41

x= 53, y=41

Second Question:

Find the Surface area of the following figure below

Answers

Answer:

495

Step-by-step explanation:

Base area = 11*11 = 121

Lateral area = (11*4)*17/2 = 11*2*17 = 374

121+374=495

And pyramid consists of 4 triangles and 1 square. To find the surface area of the figure you need to find the area for those shapes. The formula for area for those shapes are.
Triangle area is A = 1/2*B*H (B meaning base and h meaning height)
Rectangle area is A = L * W (L meaning length and W meaning width)
So the you have triangles with a base of 11 and height of 17 so 11*17*(1/2). That value times 4 because there are 4 of them so you get. 374 meters^2
Then you have the rectangle which is 11*11 so 121 add that to 374 and you get 495 meters^2 so the surface area is 495 meters^2 if I did it correctly.

3x+4y=-12 x-y=10 using elimination no links or download

Answers

Answer:

x = 4, y = -6

Step-by-step explanation:

Elimination Method

3x + 4y = -12 ---- (1)

x-y = 10 ---- (2)

(2) x 4:

4(x) 4(-y) = 4(10)

4x - 4y = 40 ---- (3)

(1) + (3):

3x + 4y + (4x - 4y) = -12 + 40

3x + 4y + 4x - 4y = 28

7x = 28

x = 28/7

x = 4

Sub x = 4 into (2):

(4) - y = 10

-y = 10 - 4

-y = 6

y = -6

A bag contains white, blue and red ping-pong balls in the ratio 8 : 3 : 2. There are 10 balls. If 10 white and 10 blue balls are removed from the bag, the new ratio is ?

Answers

Answer:

the new ratio of white, red and blue balls is 6:2:1

Step-by-step explanation:

The computation of the new ratio is shown below:

If you have 10 red balls, so the blue balls is in proportion of 3:2 that means 15 would be the blue balls. In addition to this, the while balls is in proportion 8:2 = 4:1 so there is a 40 white balls

Now if 10 white and 10 blue balls would be eliminated

So there is 30 white, 10 red, 5 blue bals

Also

30 = 5 × 6

And,

10 = 5 × 2

so the new ratio of white, red and blue balls is 6:2:1

La proposición es verdadera para todos los valores de b
Todos los reales

After simplifying the inequality we get 6 < 28 which is true. Hence the given statement is true.

An inequality is a mathematical statement that uses the inequality symbol to indicate the relationship between two expressions. Both sides of an inequality sign have different expressions.

It signifies that the expression on the left should be more or smaller than the expression on the right, or vice versa. Literal inequalities occur when the relationship between two algebraic expressions is defined using inequality symbols.

The given inequality is:

3(2 - b) < 10 - 3(b-6)

Distribute the number inside the bracket,

6 - 3b < 10 - 3b + 18

Add 3n on both sides,

6 < 10 + 18

Simplifying it,

6<28

Hence,

Answer:

Step-by-step explanation:

Ok so the volume formula is:

V = π×r² × h/3

π (pi) = 3.14

² = power of two so that number times that number

Example:

3² = 3 × 3 = 9

To find the radius since the diameter is given divide by 2:

14 / 2 = 7

Next we solve the equation:
