Alright, so if the red jelly beans are x and the yellow jelly beans are y, then
(3/4)y=x. In addition, (4/5)(y-6)=x-3. Plugging 3y/4 into the equation, we get
4y/5-24/5=3y/4-3. Adding 24/5 to both sides and subtracting 3y/4 from both, we get 4y/5-3y/4=24/5-3. Multiplying 4y/5 by 4/4, 3y/4 by 5/5, etc to get a denominator of 20 we get 16y/20-15y/20=96/20-60/20. Multiplying both sides by 20, we get 16y-15y=96-60 and y=36
Answer:
None of the answers are correct.
Step-by-step explanation:
Maria's answer is incorrect:
1. "-1" is the y-intercept. 3x/4 is your rise/run.
2. Start from -1 on the y-axis.
3. Go up 3 units above, then 4 units to the right.
<u>4. This leads up to being not on the line.</u>

Peter's answer is incorrect:
1. "-1" is the y-intercept. -4x/3 is your rise/run.
2. Start from -1 on the y-axis.
3. Go down 4 units below, then 3 units to the right.
<u>4. This leads up to being not on the line.</u>

Step-by-step explanation:
42/48
Simply divide, so, 42/2 = 21, and 48/2 = 24
21/3 = 7, and 24/3 = 8
7/8 = 42/48
Simplified form would be : 7/8
