Which of the following phrases could represent the expression k - 4? a number subtracted from four four less a number a number d

Hey!

Your answers are:

- 4 less than a number

- A number decreased by 4

Let k represent "a number". "k" is a variable, and variables are unknown.

-4 is subtracting 4. That means you're subtracting 4 from a number. -4 also means that the number is decreasing by 4. Therefore, those 2 are your answers.

<em>I hope this helps!</em>

Answer:

22 tickets

Step-by-step explanation:

I assume you're asking about question 2

To find a fraction of a whole number you divide by the bottom number and multiply by the top number. If 2/3 are kids tickets then 1/3 are adult tickets so you divide by 3 and multiply by 1

$66 \div 3 = 22 \times 1 = 22$
