Step-by-step explanation:
16 kg= 8 hours (divide by 8 to find 1 hour how many kg)
2kg=1 hour ( multiply by 9 as we need to find 18 kg
so 9 hours=18kg
So it'll take 9 hours for 18 kg of dough to be made
Hope this helps!!!
Have a nice day:)

You know that two expressions are equivalent when if you substitute in your values and simply the expressions, they have the same answer.
Answer:
all work is shown and pictured
Answer:
C.
Step-by-step explanation:
WE need to convert the given equations into the standard form
(x - a)^2 + (y - b)^2 = r^2 where r = the radius.
x^2 + y^2 + 12x - 20y+ 132 = 0
(x + 6)^2 - 36 + (y - 10)^2 - 100 = -132
(x + 6)^2 + (y - 10)^2 = -132 + 36 + 100 = 4
giving a radius of 2
x^2 + y^2 + 12x - 20y + 55 = 0
will give a right hand side of -55 + 36 + 100 = 81 giving radius 9.
x^2 + y^2 - 12x+ 20y + 127 = 0
- gives right hand side of -127 + 36 + 100 = 9 giving a radius of 3.
