If you distribute -5 to the things in the parenthesis you would get 10k-20 which is the same as -5(-2k+4)
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:
Step-by-step explanation:
1. ¹/₃ × π × r² × l:so 33.9.29cm³
2. π × r² × l:so π x 2² x 3.5=43.98ft³
3.¹/₃ × π × r² × l, to get the radius from diameter you divide the diameter by 2 so it would look like: ¹/₃ × π x 4² x 12= 201.06in³
4.352cm³
5. cone: 1/3 πr²h
Cylinder: πr²h
cone : 33 Cylinder = 3 x 33 = 99 in³
