Question 86621: The problem I am struggling with is as follows:
part a. If one inch on a map represents 35 miles, how many miles are represented by 3 inches? 10 inches? n inches?
This is what I have done so far:
35 miles to 1 inch = x miles to 3 inches
35:1 = x:3 (cross multiply)
x = 105
35 miles to 1 inch = x miles to 10 inches
35:1 = x:10 (cross multiply)
x = 350
35 miles to 1 inch = x miles to n inches
35:1 = x:n (cross multiply)
x = 35n
part b. Los Angeles is about 1000 miles from Portland. About how many inches apart would Portland and Los Angeles be on this map?
Don't have any clue how to set this problem.
Thank you for your help.
Sincerely,

Question 86619: The problem I need help with is as follows:
A family uses 5 gallons of milk every 3 weeks. At that rate, how many gallons of milk will they need to purchase in a year's time?
This is what I have tried --
5 gallons : 3 weeks = x gallons : 52 weeks
5/3 = x/52 (cross multiply)
3x = 260 (divide by 3)
x = 86.6 or 87 gallons
Thank you for any help.

Question 95417: the length of a rectangle is 8 more than twice the width. The ratio of length to width is 12 to 5. Find the length and the width of the rectangle.
(I tried solving it as 12/5 = 2x+8/2x. I then cross multiplied and got 5(2x+8)=12(2x). I used the distributive property to get 5 times 2x+40=12 times 2x. I do not know how to solve past there though.)

Question 95412: The ratio of the areas of two triangles is 8 to 5. The altitude of one triangle is 5 centimeters more than the altitude of the other while the bases are each equal to 10 centimeters. Find the altitude of each triangle.
(I have tried to convert the area into an altitude so both sides will be equal, but I am not sure what to do to solve it like that.)
