Try this way:
Note,
1. that 16/2=8 it means 10/2=5.
2. that 10*3=30, it means 16*3=48
Finally for whole table:
================
forks: 16 8 48
================
spoons: 10 5 30
================
Answer:
the answer is D 1/27
Step-by-step explanation:
The <em>xy</em>-plane has a normal vector of 〈0, 0, 1〉, and any plane parallel to it will have the same normal vector.
Then the equation of the plane through (6, 3, 2) that is parallel to the <em>xy</em>-plane has equation
〈<em>x</em> - 6, <em>y</em> - 3, <em>z</em> - 2〉 • 〈0, 0, 1〉 = 0
==> <em>z</em> - 2 = 0
==> <em>z</em> = 2
X+20 because x= origanal amount +20 more
