Maurice has completed 64 pages of the research paper he is writing. That is 80% of the required length of the paper. What is the required length of the paper?

80 pages

Step-by-step explanation:

Let the required length of paper = x

Hence:

80% of x = 64 pages

80/100 × x = 64 pages

80x /100 = 64 pages

Cross Multiply

80x = 100 × 64 pages

x = 6400/80

x = 80 pages

Therefore, the required length of the paper = 80 pages

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
