Answer:
$1
Step-by-step explanation:
6/$2 = 3/$1
For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1
Circle's Standard Form Equation:

First you need to substitute the C (0,-2) in the equation, where: Xo = 0 and Yo = -2;

Now you substitute the Point (3,-5) values in the last expression, where: X = 3 and Y = -5;

Now you get the R^2 value and substitute in the equation that you found putting the C values on it:

Here is your standard form equation of the circle.
Answer:
6 glasses.
Step-by-step explanation:
Mark drank a total of 10 glasses of water and iced tea yesterday.
Each glass of water contained 8 ounces.
Each glass of iced tea contained 12 ounces.
All together he drank 96 ounces.
Given a system of simultaneous equations:
x + y = 10
8x + 12y = 96
This depicts that there are x glasses of water and y glasses of iced tea.
Solving the simultaneous equations:
x + y = 10 ... (i)
8x + 12y = 96 ... (ii)
Multiplying (i) by 8 and (ii) by 1 gives;
8x + 8y = 80 ... (i)
8x + 12y = 96 ... (ii)
Subtracting (i) from (ii) gives;
4y = 16 , y = 16/4 = 4
So mark drank 4 glasses of iced tea and 10 - 4 = 6 glasses of water.
