Move 50x to the opposite sude so 50x-200>-75
move 200 over so 50x> 125
divide so x>2.5
The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
#2 Answer: x=4
if 5^2 = 25 than 2^2=x
It means that x=4
#8 Answer: 3
let the space for number be 0 than
420*6 = 2520
next stage is to find the remainder:
2538-2520=18
than 18/6 = 3.
The missing number is 3
7/8 of a gallon
2/3=16/24
7/12=14/24
2 1/8=51/24
14+16=30
51-30=21
so your final answer is 21/24 or 7/8
