Given:
15 is decreased by three times a number, the result is 21.
To find:
The equation for the given statement and solve it.
Solution:
Let n be the unknown number. Then,
Three times of a number =
15 is decreased by three times a number =
It is given given that the result after subtraction is 21. So,
Divide both sides by -3.
Therefore, the required equation is and its solution is . Hence, the correct option is (a).
Answer:
13 cm
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the side length )
Given
V = 2197, that is
s³ = 2197 ( take the cube root of both sides )
s = = 13 cm
