Hi!!! yall's are so cute! I love iron man wish you the best!
Answer:
multiply by the reciprocal
Step-by-step explanation:
when you divide fractions, you can use the method KCF or keep change flip. you would keep the first fraction as it is, change the division sign to a multiplication sign, and find the reciprocal of the second fraction. finally, you multiply both the numerators and the denominators together and you get your answer
Answer:
Hey there!
8 is the correct answer.
It is 16 times greater than the digit to it's right.
Let me know if this helps :)

Answer:
First equation: 1/2
Second equation: -1/3
Step-by-step explanation:
We get the following equations:
first equation
2nd equation
Then, to obtain opposite terms for the x variable, we need to identify the coefficient of the x for the 1st equation and the 2nd equation as:
The coefficient for x in the 1st equation is
and the coefficient for x in the 2nd equation is ![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Finally, we need to multiply 1st equation with the coefficient of the 2nd equation and multiply the 2nd equation with the negative of the coefficient of the 1st equation.
We multiply by the negative of the coefficient of the 1st equation because we need to find opposite terms for x.
So, the first equation is equal to:
The second equation is:
![(\frac{1}{2}x+\frac{3}{4}y)*\frac{-1}{3} =-3*\frac{-1}{3} \\\frac{-1}{6}x+\frac{-1}{4}y=1](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7Dx%2B%5Cfrac%7B3%7D%7B4%7Dy%29%2A%5Cfrac%7B-1%7D%7B3%7D%20%3D-3%2A%5Cfrac%7B-1%7D%7B3%7D%20%5C%5C%5Cfrac%7B-1%7D%7B6%7Dx%2B%5Cfrac%7B-1%7D%7B4%7Dy%3D1)
Now, the coefficients for x, 1/6 and -1/6, are opposite terms.
