An open cylindrical tank is 150 feet in diameter and 180 feet high. The lateral surface area of the tank (no top and no bottom) is to be painted with paint that covers 225 square feet per gallon. When filled each cubic foot of the tank holds approximately 7.5 gallons of gasoline valued at $2.75 per gallon.
A. Find the number of gallons of paint required for a single coat of paint.
B. Find the total value of the gasoline in the filled tank

Classify the linear equation for each system:
a) Line 1: $y = \frac{- 1}{4} x - 4$
Line 2: $x + 4 y = - 16$
b) Line 1: $y = - 2 x + 6$
Line 2: $y = \frac{1}{2} x + 1$
c) Line 1: $y = \frac{2}{3} x + 3$
Line 2: $y = \frac{2}{3} x + 4$
I) This system of equations is:
1) consistent independent
2) consistent dependent
3) inconsistent
II) This means the system has:
1) a unique solution
2) no solution
3) infinitely many solutions

Contrary to a popular belief, equation in math also contains things like inequalities and expressions that require logic and verbal explanations. This is where equation help becomes useful as you look at the answers below. See equation problems submitted by students like you and explore the answers. It will help you to understand the logic as you approach equation algebra and study expressions examples. These are not as complex as they may seem once you learn how to connect expressions and equations and understand them as a finite combination of symbols, depending on use.
