Answer:

33

Step-by-step explanation:

6x - 3y

=> x = 5, y = -1 Substitute in the above equation,

=> 6(5) - 3(-1)

=> 6(5) + 3

=> 30 + 3

=> 33

the perimeter of an equilateral triangle is 150cm. If the length of the altitude of the triangle is x√3cm, what is the value of
jenyasd209 [6]

Answer:

X = 25

Step-by-step explanation:

To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.

Perimeter of an equilaterial triangle = 3 * s

S = side length

Perimeter = 150cm

150 = 3s

S = 150 / 3

S = 50cm

The side lengths are 50cm each since they are all equal.

To find x,

We have to divide the triangle equally into two different part.

Check the first attachment for better illustration on how the equilaterial triangle is.

Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.

From the right angle triangle, we can use pythagorean theorem to solve for x

a² = b² + c²

a = 50cm

b = 25cm

c = x√(3)

50² = [x√(3)]² + 25²

2500 = x² * 3 + 625

2500 - 625 = 3x²

1875 = 3x²

X² = 1875 / 3

X² = 625

X = √(625)

X = 25

The sum of two numbers is 43 and the difference is 19. what are the numbers?
Burka [1]
You can solve this via algebra, lets say the numbers are x and y.
x + y = 43 and x - y = 19

You can re-arrange one of the equations to get

x = 43 - y Then substitute this into the other equation, so instead of x you put this:

(43 - y) - y = 19
43 - 2y = 19
-2y = 19 - 43
-2y = -24
-y = -12
so y = 12
then you can do 43 - 12 = 31 to get both of the numbers.
so the numbers are 31 and 12
