timmy has 180 marbles, some plain and some colored. if there are 32 plain more marbles than colored, how many colored marbles does he have?

Answers

180=x+x+32 180 is equal to x(amount of colored marbles) plus x+32 (amount of plain marbles)
180=2x+32
-32+180=2x
148/2=x
74=x

74 colored marbles and 106 plain

74 (180 - 32) / 2 because if there are 32 more than the other part, it is n + (n+32)

An animal shelter has a ratio of dogs to cats that's 3:2. If there are 30 cats at the shelter, how manydogs are there?
A. 15
B. 90
C. 20
D. 45

Answers

In the question "An animal shelter has a ratio of dogs to cats that's 3:2. If there are 30 cats at the shelter, how many dogs are there" the correct answer is 45 (option D). To solve the problem, let the number of dogs be x, then dogs / cats = 3 / 2 = x / 30. i.e. 2x = 3(30) = 90. x = 90 / 2 = 45. Therefore, there are 45 dogs in the animal shelter.

An animal shelter has a ratio of dogs to cats that's 3:2. If there are 30 cats at the shelter, 45 dogs are there . 3/2 = x/30 , x= 30*3/2 =45
