The easiest way to find percent is to make the percent into a decimal and multiply. Move the decimal to places to the left to make 4.30, and multiplied by 90 equals 387, so 430 percent of 90 is 387.
When the sign of the number with the greatest absolute value is positive
150 divided by 25 equals 6. 6 times 3 equals 18. This means that you will spend $18 on gas each week.
1.) Austin would get 2.3 pounds per dollar.
2.) A customer would get 15 minutes of bike time per dollar.
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
