16*7.96=127.36
127.36ft of steel will be required.
We can follow the following steps to make an equation and solve it.
Step 1:
five less than 13 means we have to subtract 5 from 13
so it becomes 13-5
Step 2:
A number y is five less than thirteen.
Now in algebraic expressions, "is" stands for "="
So we have:

Step 3:
Solving the equation to find y.

Subtracting 5 from 13, we get :
y=8
Answer:
For the given equation the solution is y=8.
If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
The flow must be a data, but for the volume of the tank we need mathematics.
For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
V = pi * r ^ 2 * h
327.68, 262.144, 209.7152
Multiple the number by 0.8 to get the next number in the series
#1: The sum of q and 5
#2: Twelve times x
Please do as many as you can by yourself and ask questions about those that are hard for you.
