1/2 = 3/6
5 gallons of water changed it to 5/6, so that would mean 2/6 would be 5 gallons worth.
5 x 3 = 15.
Hope this helps.
Answer: OPTION A
Step-by-step explanation:
You can convert 30 kilograms to grams (
), then:
![(30\ kilograms)(\frac{1,000\ grams}{1\ kilogram})=30,000\ grams](https://tex.z-dn.net/?f=%2830%5C%20kilograms%29%28%5Cfrac%7B1%2C000%5C%20grams%7D%7B1%5C%20kilogram%7D%29%3D30%2C000%5C%20grams)
Then, if a book in the bookcase has a mass of 400 grams and you need to find the number of books of the same mass that would take to equal the mass of the bookcase, you can divide the weight of the bookcase (in grams) by the weigth of one of these books.
Therefore:
![books=\frac{30,000\ grams}{400\ grams}\\\\books=75](https://tex.z-dn.net/?f=books%3D%5Cfrac%7B30%2C000%5C%20grams%7D%7B400%5C%20grams%7D%5C%5C%5C%5Cbooks%3D75)
Answer/Step-by-step explanation:
STATEMENT ====> REASONS
1. m<AOB = 180° ==> 1. Definition of straight angle
2. m<AOF + m<FOG + m<GOB = m<AOB ==> 2. Angle Addition Postulate
3. (5x - 15)° + 90° + 2x = 180° ==> 3. Substitution
4. Solve as algebra to get x
5x - 15 + 90 + 2x = 180
Collect like terms
5x + 2x - 15 + 90 = 180
7x + 75 = 180
Subtract 75 from both sides
7x + 75 - 75= 180 - 75
7x = 105
Divide both sides by 7
7x/7 = 105/7
x = 15 ===> 4. Algebra
Answer:

Step-by-step explanation:
i used a couculator i dont have a explination
Average = Sum of numbers / Number of numbers
Average = (5 + 2 + 7 + 5.5 + 3.5 + 4 + 5 + 4.5 + 4) / 9
Average = 40.5 /9
Average = 4.5
Average = 4.5 hours.
