Suppose you have $75 to spend on gas for your whole trip. you know that gas costs $3.40 per gallon. how many gallons of gas can you buy with $75? write an equation to solve the problem. round your answer to the nearest tenth of a gallon.

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
