Walk = x + 6
Bike = x
Driven = x

x + x + x + 6 = 24
combine like terms

3x + 6 = 24
subtract 6 from both sides 

3x = 18
divide both sides by 3 to isolate x

x = 6

Walk = x + 6 = 6 + 6 = 12

12 students walk to school.

olga_2 [115]

Answer:

87.125\pi in^{2} or 87\frac{1}{8}\pi  in^{2}

Step-by-step explanation:

Given Surface Area of Cylinder = 2\pi rh+2\pi r^{2},

and also given r = 4.25 inches and h = 6 inches.

Let's Substitute r and h into the formula to find the total surface area.

Surface Area of Cylinder = 2\pi (4.25)(6)+2\pi (4.25)^{2} \\=51\pi +36.125\pi \\=87.125\pi in^{2}  or 87\frac{1}{8} \pi in^{2}
