Step-by-step explanation:
let x represent the bus
6x + 21 = 195
6x = 195 - 21
6x =174
x = 29
Answer:
x(85/100)
Step-by-step explanation:
100-15 = 85
x(85/100)
Are you trying to make an algebraic equation?
x = # of trees
y = gal of water
It would be 30x = y
You can do this by completing the square on x and y terms:
x^ - 10x + y^2 + 6y + 18 = 0
(x - 5)^2 -25 + (y + 3)^2 - 9 + 18 = 0
(x - 5)^2 + (y + 3)^2 = -18 + 9 + 25 = 16
so radius = sqrt16 = 4 answer
