Predict the next number in the sequence: 1, 4, 16, 64… 512

244

384

256

Step-by-step explanation:

Notice that:

1 * 4 = 4,

4 * 4 = 16,

16 * 4 = 64.

Each term is 4 times of the previous term.

Hence the next term would be 64 * 4 = 256.

10

step-by-step explanation:

7+3=10

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
