This is be cause when you simplify to y=.. for 4y=3x and 8y=6x, they both turn out to be y=3/4x. The constant of proportionality is 3/4 because both equations simplify to have that as a constant.

Kathy can add less than or equal to 7 books to her suitcase.
To cross off the first two choices(A&B), you input a number above 7 and then multiply it by 1 3/4 . Add it to 37 1/2 and it will be more than 50, meaning it will not fit since the suitcase can’t have more than 50 pounds in it.
To cross off C, you would multiply 1 3/4 by 7 and get 12.25. Add 12.25 to 37 1/2 and you will get 49.75 . This result would mean that you can have less than 7 books or just 7 books, leaving the answer to be D.

Answer: 1/3 chance
Explanation: If you have a 1/6 chance of rolling a four, and then you role two die, you now have two 1/6 chances, meaning you have 1/6 + 1/6, AKA, 1/3 chance
I hope this helped!

Answer:A=8-1/57=455/57=7.98
Step-by-step explanation:
1. We need to get rid of all the denominator in this equation.
- This can be done by multiplying left and right sides by the LCD.
- In the problem: 12/x = 8, the LCD is X.
12/x = 8 is now 12 = x * 8
1a. 8 * x = 8x
Now, your answer is 3/2, but It's improper. Let's convert it into a mixed number.
Subtract 3 by 2.
3 - 2 = 1
3/2 = 1 1/2
Therefore, your answer is 1 1/2. Also, the answer is 1.5.
