A42-inch board is to be cut into three pieces so that the second is twice as long as the first piece and the third is 4 times as long as the first piece. if x represents the length of the first piece, find the lengths of all three pieces

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

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

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
