hope it helps! :3 let me know if you need help with other algebraic equations!
Answer:
21/4
Step-by-step explanation:
7 + 3²(12-8)
=> 7 + 9(4)
=> 7 + 36
=> 42
Equation:-
42 / (2x4)
=> 42/8
=> 21/4
I think it's 0 since anything multiplied by 0 is, well, 0! No matter what the sign is. I believe the correct answer is 0 :)
8) This is <u>inverse </u>variation because you can multiply both sides by 3 to get y = 6/x. In this case, it matches up with y = k/x and k = 6.
============================================
10) This is <u>not </u>direct variation, nor inverse variation. We cannot write it in either y = kx or y = k/x form
============================================
12) This is <u>inverse</u> variation. Rewrite 5/(2x) as (5/2)/x or 2.5/x; note how 5/2 = 2.5, so in this case k = 2.5
============================================
14) This is <u>direct</u> variation. Multiply both sides by 4, and do a bit of rearranging and you should end up with y = (20/3)x, so we see it matches up with y = kx and k = 20/3.
============================================
16) Cross multiply to get xy = 16, then divide both sides by x to end up with y = 16/x. This equation is in the form y = k/x with k = 16, so it is actually an inverse variation equation.
Answer:
4 parfaits
Step-by-step explanation:
Given that,
Allison has a 1/2 cup of yogurt for making fruit parfait recipe 1/8 Cup of yogurt.
We need to find how many parfait can she make.
Let she can make x parfait.
![x=\dfrac{\dfrac{1}{2}}{\dfrac{1}{8}}\\\\=\dfrac{1}{2}\times \dfrac{8}{1}\\\\=4](https://tex.z-dn.net/?f=x%3D%5Cdfrac%7B%5Cdfrac%7B1%7D%7B2%7D%7D%7B%5Cdfrac%7B1%7D%7B8%7D%7D%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cdfrac%7B8%7D%7B1%7D%5C%5C%5C%5C%3D4)
Hence, she can make 4 parfaits.
