Step-by-step explanation:
to find mean
add all numbers, then divide by how many set they given
to find median
you need to arrange them ascending order
then what is the number in the middle
to find mode
find what most repeated number
Well, if
{bx - 6y = 18 and {2x - 3y = 9, you might want to try elimination
Multiply second equation by -2: bx - 6y = 18 and -2(2x - 3y = 9)
Simplified: bx - 6y = 18 and -4x + 6y = -18
Now if you add them you get: -4x + bx = 0
Then simplified: bx = 4x
divide by x: b = 4
Your final solution is b = 4.
Hope that helps!
Answer:
x=20 cm
Step-by-step explanation:
Let x be the length of equal sides.
Area of triangle=
We have to find the values of x.
We know that
Area of right triangle=
Where b=Base of triangle
h=Height of triangle
Using the formula
Area of right triangle=





Hence, the value of x=20 cm
