2 in 83628 is the tenths and 208 is the hundreds
It is 5:9 in simplest form
Answer:
<h3> 81 is your answer.☺</h3>
Step-by-step explanation:
a = 3, b = 5, and c = 6
c^2 + 3a × b
6^2 + 3(3) × 5
36+9×5
36+45
81 => Ans
Hope this helps

Problem 7: Correct
Problem 8: Correct
Problem 9: Correct
The steps are below if you are curious
===========================================================================================
Problem 7
S = 180*(n-2)
2340 = 180*(n-2)
2340/180 = n-2
13 = n-2
n-2 = 13
n = 13+2
n = 15
I'm using n in place of lowercase s, but the idea is the same. If anything, it is better to use n for the number of sides since S already stands for the sum of the interior angles. I'm not sure why your teacher decided to swap things like that.
===========================================================================================
Problem 8
First find y
y+116 = 180
y+116-116 = 180-116
y = 64
which is then used to find x. The quadrilateral angles add up to 180*(n-2) = 180*(4-2) = 360 degrees
Add up the 4 angles, set the sum equal to 360, solve for x
x+y+125+72 = 360
x+64+125+72 = 360 ... substitution (plug in y = 64)
x+261 = 360
x+261-261 = 360-261
x = 99
===========================================================================================
Problem 9
With any polygon, the sum of the exterior angles is always 360 degrees
The first two exterior angles add to 264. The missing exterior angle is x
x+264 = 360
x+264-264 = 360-264
x = 96
Janine = J = 15
Leah = L = ?
L = J + 6
L = 15 + 6
L = 21
So Leah spent $21
