The ratio of adults to children in a movie theater is 7:2. If there are 26 children in the theater, how many adults are there?

Strike441 [17]

Answer: 91. I find the easiest method for questions like this about ratios is to multiply the side of the ratio you are given a value for, in this case the right hand side (children), by a number so it equals the value given. This was 2x13 to equal 26. Then, to find the value of the other side, the adults, you must multiply the left hand side by the same number used on the right hand side. 7x13 equals 91.

Oliver works at a book store.He packed 20 identical paperbacks and 9 identical textbooks in a box .The total mass of the book wa

Natasha_Volkova [10]

Let x be the mass of the paperbacks and y be the mass of the textbook.

20x + 9y = 44.4 ----------- (1)
25x + 10y = 51 -------------(2)

(1) x 10:
200x + 90y = 444 --------(1a)

(2) x 9:
225x + 90y = 459 --------(2a)

(2a) - (1a):
25x = 15
x = 0.6 -------- sub into (1)

20 (0.6) + 9y = 44.4
12 + 9y = 44.4
9y = 44.4 - 12
9y = 32.4
y = 3.6

So the paperback's mass is 0.6 pounds and textbook is 3.6 pounds
