Answer:
book 25; pen 8
Step-by-step explanation:
If we let b and p represent the cost of a book and a pen, respectively, then the two purchases can be written as ...
7b +4p = 207
5b +5p = 165
Multiply the second equation by 4/5 and subtract the result from the first equation:
(7b +4p) -4/5(5b +5p) = (207) -4/5(165)
3b = 75 . . . . simplify
b = 25 . . . . . divide by 3
Dividing the second equation by 5 gives ...
b + p = 33
Solving for p, we have ...
p = 33 -b = 33 -25 = 8
The cost of an exercise book is 25; the cost of a pen is 8.
The formula for circumference is πd.
Diameter is 2r.
5 x 2 = 10
Use 3.14 for π.
10 x 3.14 = 31.4 yards

Divide the actual distance of the scale by the map distance of the scale, which is 15/0.25 = 60. This shows that the scale is 1 cm:60 miles.
If the distance between two cities on a map is 6.8 cm, multiply by 60 to get the real distance between the two cities in miles, which is 408 miles.
408 miles
