A marine biologist discovered species with a diameter of 0.00085 inches. Express this measurement using scientific notation.

8.5 or 8.50

Step-by-step explanation:

Move the decimal to the right four times, it will be in the middle of the 8 and 5.

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
