Answer:
1 slice will be left because there are 16 slices and 15 guests
Step-by-step explanation:
This is the concept of algebra, to get the slope of the line we need to rewrite the equation in slope intercept form y=mx+c, where m=slope, c=y-intercept.
Therefore re-writing our expression in slope-intercept form we get:
7x-3y=10
-3y=-7x+10
y=7/3x-10/3
The slope=7/3
hence we conclude that the slope of the line perpendicular to this is -3/7
Start by making the denominators equal.
1/3 becomes 4/12
1/6 becomes 2/12
and you have 5/12.
Add together to get 10/12.
Once simplified, the answer should be 5/6.
