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:
Step 3
Step-by-step explanation:
She made her first mistake in Step 3.
This is because 4/7 is actually less than 5/3.
Step 1 and 2 are mathematically accurate.
1/2 is less than 1.
So, since 4/7 is only greater than 1/2 and not greater than 1 as compared to 5/3 which is actually greater than 1, she should have concluded that 4/7 is less than 5/3.
Therefore, Step 3 contains the mistake.
Answer:
false
Step-by-step explanation:
20 - 1 = 1 + 17
Simplify each side.
19 = 18
Since 19 = 18 is a false statement, the equation is false.
