2 quarters,4 nickels, and 7 dimes 50+20+70=140 she has 1.40$"
3(4x - 2) = 2(6x - 3)
First, expand. / Your problem should look like: 12x - 6 = 12x - 6
Second, since both sides are equal, there and infinite solutions.
Answer: B) infinite solutions.
Answer:
Indirect variation
Step-by-step explanation:
If two variables change in inverse proportion, then it is called indirect variation.
xy = k where k is a constant.
5*2 = 10
10*1 =10
![15*\dfrac{2}{3}=5*2=10\\\\\\20*\dfrac{1}{2}=10](https://tex.z-dn.net/?f=15%2A%5Cdfrac%7B2%7D%7B3%7D%3D5%2A2%3D10%5C%5C%5C%5C%5C%5C20%2A%5Cdfrac%7B1%7D%7B2%7D%3D10)
So, this is indirect variation.
1/3 = 4/12
(4/12 + 11/12) * 2/3
= 15/12 * 2/3
15/ 12 can also be written as 5/4
5/4 * 2/3 = 10/12
10/12 can be simplified into 5/6
Therefore, the answer is 5/6
