Mean Absolute Deviation I'm pretty sure. Hope this helped, have a great day! :D
Answer:
x= -5/2
Step-by-step explanation:
4 - (2x+4)=5
4-2x-4=5
-2x=5
x=-5/2
Each person would receive 1.5625 pounds of berries.
Answer:
86 milkshakes and 63 ice cream were sold
Step-by-step explanation:
Let the amount of milkshake sold be x
Let the amount of ice cream sold be y
If she sold 149 milkshakes and ice cream cones then;
x+y = 149 ... 1
If the milkshakes sold for $4 and the ice cream cones for $3, with total amount #533 collected then;
4x + 3y = 533 ....2
Solve both equations simultaneously
x+y = 149 ... 1 * 4
4x + 3y = 533 ....2 * 1
________________________
4x+4y = 596
4x+3y = 533
Subtract
4y-3y = 596-533
y = 63
since x +y = 149
x+63 = 149
x = 149 - 63
x = 86
Hence 86 milkshakes and 63 ice cream were sold
Answer:20π
Step-by-step explanation:
equation of the circle
(x+3)² + (y-5)² = r²
now, (-9, -3) lies on it
So, (-9+3)² + (-3-5)² =r²
36+ 64 = r² =100
hence, r =10
So, circumference = 2πr = 20π
