x = 18.
Step-by-step explanation:
x + 9.5 = 27.5
Subtract 9.5 from both sides:
x = 27.5 - 9.5
x = 18 (answer).
Answer:
y = 1500 - 200x
Step-by-step explanation:
y would be the amount of water remaining in the pool
x would be the amount of hours that have passed.
So the only change I made was to convert 400 every 2 hrs to 200 every hour.
makes sense?
The sum of the measures of the angles of a polygon of n sides is 180(n - 2).
Set that expression equal to 1800 and solve for n, the number of sides.
180(n - 2) = 1800
Divide both sides by 180
n - 2 = 10
Add 2 to both sides
n = 12
The polygon has 10 sides.
