B I’m pretty sure okay bye
K added to 10 gives you 4 times the value of K.
If you wanted to solve the expression:
Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k
If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.
We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
Answer:
900
Step-by-step explanation:
Since water piper is a cylinder shape, the equation to calculate the volume of a cylinder is:
Volume = radius* radius * 3.14 * height
volume = 5 * 5 * 3.14 * 7
Volume = 25 * 3.14 * 7
Volume = 25 * 21.98
Volume = 549.5
The volume of water take to fill the pipe is 549.5 cubic centimeter.
