Answer:
w=108
Step-by-step explanation:
Using the formula
P=2(l+w)
Solving for w
w=P
/2﹣l = 240
/2﹣12 = 108
First step
5.(2x-8)
= (5.2x) + (5. (-8) )
=10x + (-45)
note :(+) . (-) = (-)
so + (-45)= (-45)
Add 15 to this equation
= 10x -40 +15= -15
=10x -25= -15
Leave x alone and make it positive
By the way, if you put (-25) in the right term, this number's notation (I mean -) will change
Namely
= 10x= (-15)+25
=10x= 10
x=1
Hope it helps :)
P.s. I dont know mathematical terms that's why i couldn't explain it properly but i tried to help as far as i can :)
Answer:
Center (7,2); Radius - Square Root of 10
Step-by-step explanation:
Equation for a Cricle:
(x−h)^2 + (y−k)^2 = r^2
Where:
h = x-coordinate of the center of the circle
k = y-coordinate of the center of the circle
r = radius of the circle
For this problem, your h = 7, k = 2, and r = square root of 10
In an hour, 80 people could ride the ferris wheel. So, that means in 3 hours 240 people could ride it.
