Answer:
9 boxes are packed and 10 brownies are left over.
Step-by-step explanation:
Carrie made 127 brownies and packed 13 in each box.
The number of boxes packed are , 127/13= 9 10/13
Which means that 9 boxes were packed and 10 brownies were left over.
(x - h)^2 + (y - k)^2 = r^2
x^2 + (y + 6)^2 = 100
we can rewrite this as
(x-0)^2 + (y - -6)^2 = 10^2
the center is (0,-6) and the radius is 10
Answer:
x=124.75
Step-by-step explanation:
Sum of angles of a triangle=180°
(x-40)+(x-20)+(1/2- 10)=180°
(x-40)+(x-20)+(−9.5)=180°
x-40+x-20−9.5=180°
x+x-40-20-9.5=180°
2x−69.5=180°
2x=180°+69.5
2x=249.5
2x/2=249.5/2
x=124.75
