You increase the size of a page by 50%. Then you decrease it by 50%. What is the size of the page now?

Answers

We can't tell what size the page is now, because you never told us
what size it was before all the shenanigans started. All you gave us
was a couple of ratios.

And you didn't even tell us WHAT was increased and decreased ...
was it the length of the sides, or was it the area of the page ?
__________________________________________

If it was the length of the sides ...

Let's say the page was 8" high and 4" wide.

Increase lengths by 50% :   Now it's 12" high and 6" wide.

Decrease lengths by 50% :   Now it's 6" high and 3" wide.

   The sides are now 3/4 as long as they started out,
   and the area is 9/16 of what it started out.

The answer is smaller than started with

To win a game, you need at least 45 points. Each question is worth 3 points. Write and solve an inequality that represents the number of questions you need to answer correctly to win the game.

Answers

Answer:

$3x\geq 45$ ; At-least 15 questions.

Step-by-step explanation:

Let x represent the number of questions you need to answer correctly..

We have been given that each question is worth 3 points. The points earned from answering x right questions would be $3x$ .

Since we need at-least 45 points to win the game, so points earned from answering x questions would be greater than or equal to 45. We can represent this information in an equation as:

$3x\geq 45$

$(3x)/(3)\geq (45)/(3)$
