Answer: Option D, 8/12
Answer:
60
Step-by-step explanation:
Let the original number be x.
According to the question we can write as (2/3)x+20x
On rearranging x−(2/3)x=20
Now taking the L.C.M od 1 and 3 is 3
(3x−2x)/3=20
x/3=20
Again by transposing x=60
So the original number is 60
Answer:
b.
Step-by-step explanation:
(5x^5 + 4) - (2x^3+9)+(6x^5-x^3)
5x^5 + 4 - 2x^3 - 9 + 6x^5 - x^3
5x^5 + 6x^5 = 11x^5
-2x^3 - x^3 = -3x^3
+4 -9 = -5
Answer:
<h2>x = 2</h2>
Step-by-step explanation:
We know that 5 times x has to be greater than 9, since the equation's outcome is not negative. We know that 1 + 9 = 10, so 5 times x must equal 10.
5 x 2 = 10
5 x 2 - 9 = 1
Therefore, x = 2
Im not sure wym but i think the answer is 20
