Answer:
2/3 [3x - 15] =x-10
open the brackets first
[2/3 x3x] -[2/3 x15 =x - 15
2x - 10 =x - 10
put the like terms together
2x -x =-10 +10
x=0
Step-by-step explanation:
Nayeon and her aunt hiked 154 meters before they had lunch and after they had lunch, they hiked 84 more meters. all together they hiked 238 meters. The dad and sister hiked 167 meters before they had lunch and after they had lunch, they hiked 62 more meters. all together they hiked 329 meters. The difference in meters between Nayeon and her aunt and her dad and her sister (before lunch) is 13 meters.
328/4=82
82(7)=574
574 liters of Petrolyn oil is the answer.
Hope this helps!
Answer: 65.94 square meters
This value is approximate since pi = 3.14 is approximate
------------------------------------------------------------------
Work Shown:
Area of circle = pi*(radius)^2
A = pi*r^2
Area of smaller circle = pi*2^2 <<--- replace r with 2; which is the smaller radius
Area of smaller circle = 4*pi
Area of larger circle = pi*5^2 <<--- replace r with 5 (since 3+2 = 5); which is the larger radius
Area of larger circle = 25*pi
Area of shaded region = (area of larger circle)-(area of smaller circle)
Area of shaded region = 25*pi - 4*pi
Area of shaded region = 21*pi
Area of shaded region = 21*3.14 <<--- replace pi with 3.14 (approximate)
Area of shaded region = 65.94 square meters
