In Martha's gumball machine the ratio of the number of orange to green to pink gumballs is 6 : 5 : 9. If the number of pink gumballs minus the number of green gumballs is 52, how many gumballs are coloured orange?

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

hm let me think hm think think hm think yes
