Answer: 91 students ride the bus
For this problem, you can set up a proportion where:
w = those who walk to school
r = those who ride the bus to school
Then include the ratio (1:7) as a fraction (1/7) and the value that is known (13).
Cross multiply (create an "x").
Answer:
The correct answer is B.) (4x - 7 + 5x + 5) and (9x + 12).
We shall use the unitary method.
We shall convert the scale factor for 1 inch.
Here the scale factor given is 1/4 in : 32 ft.
This means 1/4 inches on the drawing represents 32 ft of the original.
Hence 1 inch shall represent
= 32 × 4 = 128 ft
So for 9.25 in it shall represent
=9.25 × 128
= 1,184 feet
The actual length of the cruise ship is 1,184 ft.
