Answer:
x = 14
Step-by-step explanation:
Given
5(x - 10) = 20 ( divide both sides by 5 )
x - 10 = 4 ( add 10 to both sides )
x = 14
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
The cube root 80 = cube root 8 * cube root 10 = 2 cube root 10
as a decimal this is 2*2.1544 = = 4.31 to nearest hundredth
