Kurt has a collection of 155 United States and Canadian stamps. He has 1.5 times as many United States stamps as Canadian stamps

stealth61 [152]

Kurt has 93 United States stamps in his collection

Step-by-step explanation:

The given is:

Kurt has a collection of 155 United States and Canadian stamps
He has 1.5 times as many United States stamps as Canadian stamps

We need to find how many United States stamps Kurt has in his collection

Assume that kart has x Canadian stamps

∵ kart has x Canadian stamps

∵ He has 1.5 times as many United States stamps as Canadian stamps

- That means the number of United States stamps is 1.5 times

the number of the Canadian stamps

∴ The number of the United States stamps = 1.5 x

∵ Kurt has a collection of 155 United States and Canadian stamps

- Add the two numbers of stamps and equate the answer by 155

∴ x + 1.5 x = 155

- Add like terms

∴ 2.5 x = 155

- Divide both sides by 2.5

∴ x = 62

∵ The number of United States stamps = 1.5 x

∴ The number of United States stamps = 1.5(62)

∴ The number of United States stamps = 93 stamps

Kurt has 93 United States stamps in his collection

PLEASE!! I NEED HELP

elixir [45]

Answer:

Option A, $\frac{1}{7}$

Step-by-step explanation:

Step 1: Determine the numbers that are multiples of 3

8 → Not a multiple of 3

9 → Multiple of 3

14 → Not a multiple of 3

19 → Not a multiple of 3

25 → Not a multiple of 3

34 → Not a multiple of 3

38 → Not a multiple of 3

Step 2: Determine the probability of chosing a multiple of 3

Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:

$\frac{(1\ multiple\ of\ 3)}{7\ total\ numbers}$

$\frac{1}{7}$

Answer: Option A, $\frac{1}{7}$
