Answer:
n = y/(r+s)
Step-by-step explanation:
(rn+sn) / y = 1
Multiply each side by y
(rn+sn) / y *y= 1*y
rn+sn = y
Factor out n
n(r+s) = y
Divide each side by (r+s)
n(r+s) / (r+s) = y/(r+s)
n = y/(r+s)
its the second option because it is clearly shown and described on the screen
Answer:
$1200
Step-by-step explanation:
On an annual basis, Susie will be paying ($300×12) = $3600 the first year, and ($50×12) = $600 more each year after. The average rent over the 5-year period will be the rent in year 3, or $3600 +2×600 = $4800.
Susie's total rent for the period is ...
$4800×5 = $24,000
and Bailey's total commission will be ...
0.05 × $24,000 = $1200
_____
The sequence of annual rents is an arithmetic sequence with first term 3600 and common difference 600. The total of n terms of an arithmetic sequence will be ...
sum = (2·a1 +d(n -1))×(n/2)
= (2·3600 +600(5-1))(5/2) = 24000 . . . for n=5
This is the average term multiplied by the number of terms. When the number of terms is odd, the average term is the middle one (term 3 when there are 5 terms).

Problem 12
Comment
A cyclic quadrilateral (a 4 angled quadrilateral where all 4 corners touch the circumference of a circle), has the property that opposite angles add up to 180 degrees.
Formula
4x + 9 + 3x + 3 = 180 Collect like terms
Solution
4x + 3x + 9 + 3 = 180 Combine
7x + 12 = 180 Subtract 12 from both sides
7x + 12 -12 = 180 - 12 Combine
7x = 168 Divide by 7
7x/7 = 168/7
x = 24
Answer
x = 24
Problem 13
Comment
Same comment as was given for problem 12
Formula
3x + 2 + 3x - 32 = 180 Collect like terms
Solution
3x + 3x +2 - 32 = 180 Combine
6x - 30 = 180 Add 30 to both sides
6x -30+30 = 180 + 30
6x = 210 Divide by 6
6x/6 = 210/6
x = 35
Answer
x = 35
