Answer:

Step-by-step explanation:

j=d-27

d=2j-2, using j from above makes this equation become

d=2(d-27)-2

d=2d-54-2

d=2d-56

-d=-56

d=56, since j=d-27

j=56-27

j=29

So John is 29 and Dre is 56

Answer:

The small tire would make about  127 rotations.

The large tire would make about  38 rotations.

b. Would you rather ride a bicycle made with two large wheels or two small wheels? Explain.

Two large wheels. Because the larger wheel makes a smoother ride and you spend less energy in order to move, compared to smaller wheels. Also, the larger the diameter, the further it can travel over one revolution.

A bicycle with would allow you to travel farther with each rotation of the pedal.

The larger one. Because in one rotation the larger wheel moves 188.49 inches and the smaller one 56.55 inches.

C= 188.49\text{inches}

C= 56.55\text{inches}

Step-by-step explanation:

- Big wheel 60 inches

- Small wheel 18 inches.

a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.

Considering: C=\pi d

Large tire:

C=60\pi

C= 188.49\text{inches}

$C=\frac{188.49}{12} = 15.7 \text{feet}$

$\frac{600 }{15.7} = 38 \text{rotations}$

Small tire:

C=18\pi

C= 56.55\text{inches}

$C=\frac{56.55}{12} = 4.71 \text{feet}$

$\frac{600 }{4.71} = 127 \text{rotations}$
