The total water usage for a city is 15,000 gallons each day. Of that total, 19% is for personal use and 44% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 10,500 | |
| 8,000 | |
| 3,300 | |
| 3,750 |
44% of the water consumption is industrial use and 19% is personal use so (44% - 19%) = 25% more water is used for industrial purposes. 15,000 gallons are consumed daily so industry consumes \( \frac{25}{100} \) x 15,000 gallons = 3,750 gallons.

The __________ is the greatest factor that divides two integers.
least common multiple |
|
greatest common multiple |
|
greatest common factor |
|
absolute value |
The greatest common factor (GCF) is the greatest factor that divides two integers.
Solve 5 + (5 + 4) ÷ 2 x 2 - 22
| 10 | |
| \(\frac{1}{3}\) | |
| 1 | |
| 1\(\frac{2}{5}\) |
Use PEMDAS (Parentheses, Exponents, Multipy/Divide, Add/Subtract):
5 + (5 + 4) ÷ 2 x 2 - 22
P: 5 + (9) ÷ 2 x 2 - 22
E: 5 + 9 ÷ 2 x 2 - 4
MD: 5 + \( \frac{9}{2} \) x 2 - 4
MD: 5 + \( \frac{18}{2} \) - 4
AS: \( \frac{10}{2} \) + \( \frac{18}{2} \) - 4
AS: \( \frac{28}{2} \) - 4
AS: \( \frac{28 - 8}{2} \)
\( \frac{20}{2} \)
